In procurement, electronic signature is often treated as the final administrative step after negotiations are complete. The buyer uploads the contract, adds the signatories and sends the document for signature.

In practice, electronic contract signing is also a legal, security and governance process.

A fast signature workflow creates little value if the wrong version is signed, the person signing lacks authority, the chosen signature method is unsuitable or the evidence cannot be retrieved when a dispute occurs.

This article explains how electronic signatures are used in procurement, how electronic and digital signatures differ, what buyers should check before sending a contract for signature, and how to choose a signature method that reflects the risk of the transaction.

Important: This article provides general procurement guidance. Electronic-signature requirements vary between jurisdictions and document types. Obtain appropriate legal advice for regulated, unusual, high-value or cross-border transactions.

Quick answer

An electronic signature is a method through which a person indicates agreement or approval electronically.

Electronic signatures can make procurement contracting faster and easier, but the buyer must still confirm:

• The correct contract version is being signed.
• The signatories can be identified.
• Each signatory has authority to represent the relevant legal entity.
• The chosen signature method is legally and commercially appropriate.
• The signed document and supporting evidence can be retained and retrieved.

In the EU, an electronic signature cannot be rejected as evidence solely because it is electronic. However, only a qualified electronic signature automatically has the equivalent legal effect of a handwritten signature under eIDAS.

What is an electronic signature?

An electronic signature is the broad concept of using electronic data or an electronic process to indicate that a person intends to sign, approve or accept something.

Depending on the circumstances and applicable law, an electronic signature may involve:

• Typing a name into a document.
• Clicking an approval or acceptance button.
• Drawing a signature on a touchscreen.
• Signing through a link sent to an email address.
• Confirming identity through multi-factor authentication.
• Using a certificate-based digital signature.
• Using an advanced or qualified electronic signature.

The visible image of a handwritten signature is not necessarily the most important part of the process.

From a procurement perspective, the stronger evidence usually comes from the complete signing record. This may show:

• Which document was presented.
• Who received the signature request.
• How the person was authenticated.
• When the document was opened and signed.
• Whether the document changed after signature.
• Which certificate or signing method was used.
• Which IP address, device or identity service was involved.
• Whether all required signatories completed the process.

The buyer should therefore think of electronic signature as an evidence process, not simply as an image placed on a PDF.

Electronic signature and digital signature are not the same thing

The terms electronic signature and digital signature are often used as if they mean the same thing. They are related, but they describe different concepts.

Electronic signature

Electronic signature is the wider legal and business concept. It describes an electronic action through which a person indicates an intention to sign or approve a document.

Digital signature

A digital signature is a technical method based on cryptography. It can help verify the source of a signed document, detect later changes and connect a signature to a digital certificate or identity.

A digital signature can therefore support an electronic signature, but not every electronic signature uses digital-signature technology.

Government of Canada guidance similarly distinguishes the broad electronic-signature concept from digital signatures that use cryptographic methods and public-key infrastructure.

For buyers, the practical distinction is important:

The electronic signature represents the act of approval. The digital-signature technology helps produce and protect evidence of that act.

Why procurement teams use electronic signatures

Electronic signatures can create significant practical advantages during contract execution.

Faster contract completion

Paper documents may need to be printed, posted, scanned and circulated between several locations. An electronic workflow can allow internal and external signatories to complete the process without handling physical documents.

This is particularly useful when:

• The supplier is located in another country.
• Several internal approvals are required.
• Multiple supplier representatives must sign.
• The agreement contains several separate documents.
• A contract must be completed before a defined implementation date.

Better visibility

A controlled workflow can show which party has signed, which signature is outstanding and whether a request has expired.

The buyer can follow up based on the actual contract status rather than sending repeated emails asking whether the document has been signed.

Stronger document control

A well-configured signing process reduces the risk that different parties sign different versions.

The final contract package can be locked before signature and distributed consistently to all signatories.

Improved auditability

The signature platform may create an evidence record containing events, timestamps, authentication details and information about the signed document.

This can support:

• Internal audit.
• Contract compliance.
• Dispute management.
• Supplier governance.
• Regulatory reviews.
• Confirmation that delegation-of-authority rules were followed.

Easier contract handover

When electronic signature is integrated with a contract repository or contract lifecycle management process, the signed agreement can be transferred directly into contract management.

The contract owner can then receive the final agreement together with key dates, obligations, deliverables and renewal information.

Are electronic signatures legally binding?

Electronic signatures are recognised in many legal systems, but “electronic signatures are legally binding” is too broad a statement to use without qualification.

The correct question is usually not:

Is electronic signature legal?

A better set of questions is:

• Is an electronic signature permitted for this document?
• Does the chosen method identify the signer sufficiently?
• Is there evidence of the signer’s intention?
• Did the person have authority to bind the organisation?
• Can the integrity of the signed document be demonstrated?
• Are there witnessing, notarisation or form requirements?
• Can the record be retained and reproduced?
• Do the parties consent to using the electronic method?
• Which jurisdiction and governing law apply?

European Union

Under eIDAS, an electronic signature cannot be denied legal effect or admissibility as evidence solely because it is electronic or because it does not meet the requirements for a qualified electronic signature.

However, only a qualified electronic signature automatically has the equivalent legal effect of a handwritten signature.

The eIDAS framework was amended by Regulation (EU) 2024/1183 as part of the European Digital Identity Framework. Buyers working with EU contracts should therefore refer to eIDAS as amended, together with applicable national and sector-specific rules.

United States

The US Electronic Signatures in Global and National Commerce Act establishes that a contract or signature generally cannot be denied legal effect solely because it is electronic.

However, the legislation also contains conditions relating to records and specific exceptions. Other federal and state requirements may apply depending on the transaction and document.

Canada

Canada has a federal electronic-signature framework, while provinces and territories also have legislation governing electronic commerce and electronic transactions.

The appropriate method may depend on the legal requirement, transaction risk and required level of assurance. Government of Canada guidance describes several types of electronic authorisation that provide different levels of assurance.

Australia

Australian Commonwealth guidance explains that electronic signatures are valid for most Commonwealth processes, provided relevant requirements are met. The method should identify the signer and indicate the signer’s intention, and consent or specific exemptions may need to be considered.

The practical procurement conclusion

Electronic-signature laws commonly support electronic transactions, but they do not remove the need for procurement and legal teams to assess:

• Jurisdiction.
• Contract type.
• Formal requirements.
• Identity risk.
• Authority.
• Document integrity.
• Evidence retention.
• Cross-border recognition.

A platform provider’s statement that its solution is “legally binding” should not replace the organisation’s own legal and risk assessment.

Simple, advanced and qualified electronic signatures under eIDAS

For procurement professionals operating in the EU, it is useful to understand the three commonly discussed electronic-signature levels.

Simple electronic signature

“Simple electronic signature” is a commonly used expression for an electronic signature that does not meet the requirements for an advanced or qualified electronic signature.

Examples may include:

• A typed name.
• A scanned signature.
• Clicking an acceptance button.
• A basic email-link signing workflow.

A simple electronic signature may still be legally relevant and admissible as evidence. However, the strength of the evidence depends on the process, context and supporting information.

Advanced electronic signature

An advanced electronic signature must meet specific eIDAS requirements. It must be:

• Uniquely linked to the signatory.
• Capable of identifying the signatory.
• Created using data that the signatory can use under their control with a high level of confidence.
• Linked to the signed data so that subsequent changes can be detected.

An advanced electronic signature therefore provides stronger controls around identity, control and document integrity.

Qualified electronic signature

A qualified electronic signature is an advanced electronic signature that is created using a qualified signature-creation device and is based on a qualified certificate.

Under eIDAS, a qualified electronic signature has the equivalent legal effect of a handwritten signature.

Qualified electronic signatures are provided through qualified trust services. The EU/EEA Trusted List Browser can be used to verify qualified trust service providers and the qualified services they offer.

Does procurement always need a qualified electronic signature?

No.

Requiring the strongest available signature for every agreement may increase cost and make the process unnecessarily difficult for buyers and suppliers.

The signature level should reflect:

• Legal requirements.
• Contract value.
• Commercial exposure.
• Regulatory sensitivity.
• Jurisdiction.
• Identity risk.
• Risk of a later dispute.
• Consequences if the signature is challenged.
• Availability of an appropriate identity method.

The appropriate decision should be made through a risk-based company policy supported by legal, information-security and procurement expertise.

Signer identity is not the same as signing authority

One of the most important procurement controls is also one of the easiest to overlook.

A signing platform may provide good evidence that a particular individual completed the signature process. That does not automatically prove that the individual had authority to commit the supplier.

For example, the platform may verify that the signer is Jane Smith. Procurement must still determine whether Jane Smith is authorised to sign a five-year contract on behalf of Supplier AB.

Before signature, the buyer should confirm:

• The correct supplier legal entity.
• The organisation number or company-registration details.
• The signatory’s role.
• The signatory’s authority under the supplier’s governance arrangements.
• Whether a power of attorney is required.
• Whether two signatories are required.
• Whether contract value affects the authority level.
• Whether the buyer’s own signatory has sufficient internal authority.

The same distinction applies internally.

Approval and signature are separate controls:

• Approval confirms that relevant stakeholders accept the contract.
• Signature formally expresses the organisation’s agreement through an authorised representative.

A procurement manager, legal counsel, budget owner and business stakeholder may approve a contract, while another executive or authorised representative signs it.

The electronic-signature workflow should not be used to bypass internal approval requirements.

Where electronic signature fits in the procurement process

Electronic signature belongs mainly in the final part of the source-to-contract process.

A controlled process may contain the following stages.

1. Contract finalisation

The buyer confirms that negotiations are complete and that the contract accurately reflects the agreed commercial and operational position.

This includes checking:

• Main agreement.
• Price appendices.
• Specifications.
• Statement of work.
• Service levels.
• Data-processing terms.
• General terms and conditions.
• Supplier commitments.
• Implementation plan.
• Any agreed deviations.

2. Internal approval

Relevant functions approve the final agreement according to company policy.

Depending on the contract, this may include:

• Business owner.
• Procurement.
• Legal.
• Finance.
• Information security.
• Data protection.
• Quality.
• Compliance.
• Senior management.

3. Signature-method decision

The contract is assigned an appropriate electronic-signature method based on legal and commercial risk.

4. Signature preparation

The buyer or contract administrator:

• Uploads the final approved documents.
• Confirms the legal entities.
• Adds the authorised signatories.
• Defines the signing order.
• Selects authentication requirements.
• Adds any required witnessing process.
• Checks the final package before sending it.

5. Signature and validation

The parties sign the contract.

The responsible person then verifies that:

• All required signatures are present.
• The signature status is valid.
• The document has not been altered.
• Any certificates can be validated.
• The correct legal entities signed.
• The evidence record is complete.

6. Archiving

The signed contract and associated evidence are stored according to the organisation’s retention and records-management requirements.

Do not assume that permanent access through the provider’s online portal is sufficient.

The organisation should be able to retain and retrieve:

• The signed document.
• All appendices.
• The audit or evidence record.
• Relevant certificates.
• Validation information.
• Approval documentation.
• Powers of attorney where applicable.

7. Contract handover

Signature is not the end of the procurement process.

The contract should be handed over to the contract owner with:

• Roles and responsibilities.
• Deliverables.
• Milestones.
• Prices.
• Service levels.
• Reporting requirements.
• Risk controls.
• Renewal dates.
• Termination dates.
• Supplier-performance measures.

Use a risk-based signature policy

A practical electronic-signature policy should not require the same method for every transaction.

The following model is an illustration. Each organisation should adapt it to its legal environment and risk appetite.

Tier 1: Lower-risk transactions

This tier may include routine, low-value and uncomplicated documents where a simple electronic-signature process is accepted by company policy and applicable law.

Possible controls include:

• Verified business email.
• Clear signing statement.
• Controlled final document.
• Basic audit history.
• Central storage.
• Appropriate retention.

Examples might include low-risk acknowledgements or routine contract changes with limited financial or legal exposure.

Tier 2: Standard supplier contracts

This tier may cover regular commercial contracts with meaningful value or operational importance.

Possible controls include:

• Multi-factor authentication.
• Stronger signer identification.
• Tamper-evident documents.
• Detailed evidence record.
• Signing-order control.
• Automated archiving.
• Document-integrity verification.
• Confirmation of signing authority.

Tier 3: High-risk or regulated contracts

This tier may include strategic, high-value, regulated, cross-border or otherwise sensitive agreements.

Possible controls include:

• Legal review of the signature method.
• Advanced or qualified electronic signature where appropriate.
• Strong identity proofing.
• Certificate validation.
• Qualified trust services where required.
• Long-term validation or preservation.
• Enhanced evidence retention.
• Formal verification of signing authority.

NIST’s Digital Identity Guidelines provide a structured approach to identity proofing, authentication and federation at different assurance levels. Although written for US government digital systems, the assurance-based thinking is useful when procurement, legal and security teams assess electronic-signature risks.

Buyer checklist before sending a contract for electronic signature

Before sending the document, confirm the following.

Contract package

• The contract has completed negotiation.
• All approved changes have been included.
• All appendices are attached.
• References between the agreement and appendices are correct.
• No unresolved comments or tracked changes remain.
• The file names and version numbers are clear.
• The document uploaded for signature is the approved final version.

Parties and authority

• The correct buyer legal entity is named.
• The correct supplier legal entity is named.
• Registration information is correct.
• The supplier signatory has appropriate authority.
• The buyer signatory has appropriate authority.
• Any power of attorney has been obtained.
• Dual-signature requirements have been considered.

Internal governance

• Business approval is documented.
• Procurement approval is documented.
• Legal approval is documented where required.
• Financial approval is documented.
• Information-security and privacy reviews are complete where applicable.
• Delegation-of-authority requirements have been followed.

Signature method

• Electronic signature is permitted for the document.
• The selected authentication method matches the risk.
• Witnessing or notarisation requirements have been checked.
• Cross-border requirements have been considered.
• The signing order is correct.
• Signatories know what action is required.

Evidence and retention

• The platform will create sufficient evidence.
• The signed contract can be exported.
• The evidence record can be exported.
• Certificate and validation data can be retained where relevant.
• The contract will be stored in the official repository.
• The retention period has been defined.
• Continued access does not depend entirely on the provider’s portal.

Handover

• The contract owner has been identified.
• Key dates will be registered.
• Supplier obligations will be communicated.
• Performance measures will be activated.
• Implementation activities have been agreed.

Practical example: An international supplier agreement

A tactical buyer has completed negotiations with a new software supplier.

The agreement has a three-year term and includes:

• Subscription fees.
• Implementation services.
• Personal-data processing.
• Service levels.
• Information-security obligations.
• Liability provisions.
• Renewal and termination conditions.

The supplier is established in another EU country.

The buyer should not begin by simply uploading the contract into the organisation’s default signing platform.

A controlled approach would be:

Step 1: Confirm the contract package

The buyer checks that the main agreement, data-processing agreement, service description, price schedule and security appendix are all final.

Step 2: Complete internal approval

The business owner, procurement, legal, finance, information security and data-protection functions complete their required reviews.

Step 3: Confirm the parties

The buyer checks the supplier’s legal company name and registration details.

Step 4: Confirm authority

The supplier identifies its authorised signatory. The buyer checks whether evidence of authority or a power of attorney is required.

Step 5: Select the signature method

Legal, security and procurement assess the risk and determine whether the standard company method is sufficient or whether an advanced or qualified electronic signature is appropriate.

Step 6: Sign and validate

The authorised representatives sign. The completed signature and evidence are checked before the contract is marked as executed.

Step 7: Archive and implement

The full contract package and evidence are stored in the contract repository. Key obligations and dates are transferred to the contract-management process.

The value of electronic signature in this example is not only speed. It creates a structured bridge between negotiation, approval, execution and contract management.

Common mistakes in electronic contract execution

Mistake 1: Treating the signature image as the evidence

A visible handwritten-style image does not necessarily establish identity, authority or document integrity.

Review the complete signing process and evidence record.

Mistake 2: Sending the contract before approval is complete

Electronic-signature tools make it easy to send documents quickly. That speed can become a control weakness when buyers begin signature before legal, financial or business approval is complete.

Mistake 3: Signing an incomplete contract package

A signed main agreement may refer to specifications, prices or service levels that were never attached.

The buyer should confirm the completeness of the entire package before signature.

Mistake 4: Confusing identity with authority

Knowing who signed does not prove that the person was authorised to bind the organisation.

Mistake 5: Using one signature method for every contract

A routine amendment and a high-value strategic agreement do not necessarily need the same assurance level.

Mistake 6: Assuming every electronic signature is equivalent to handwriting

Under eIDAS, only a qualified electronic signature automatically has the equivalent legal effect of a handwritten signature. Other electronic signatures may still be valid and admissible, but the legal effect must not be overstated.

Mistake 7: Keeping only the signed PDF

The audit record, certificates, approval evidence and validation data may be important later.

Mistake 8: Relying permanently on the provider portal

The organisation may lose access when a subscription ends, a provider changes its service or the company migrates to another system.

Exportability and independent retention are essential.

Mistake 9: Ignoring data protection

Electronic-signature providers may process names, email addresses, identifiers, authentication data and technical event information.

Where GDPR applies, organisations should address processor obligations and use technical and organisational measures appropriate to the processing risk.

Mistake 10: Treating signature as the end of the contract process

The value expected from the supplier begins after the contract has been signed.

The executed agreement must be handed over, implemented and actively managed.

How this connects to the tactical procurement role

Electronic signature is mainly connected to the tactical procurement role because tactical buyers and category managers are often responsible for bringing a sourcing activity from negotiation to a completed contract.

The tactical buyer may be responsible for:

• Coordinating the final agreement.
• Managing internal approvals.
• Confirming the final commercial position.
• Checking the contracting parties.
• Starting the signature workflow.
• Following up outstanding signatures.
• Ensuring that the executed agreement is archived.
• Handing the contract over to the business and contract owner.

Procurement management has a supporting role.

Management should define:

• Electronic-signature policy.
• Delegation-of-authority rules.
• Risk levels.
• Approved systems.
• Contract-approval requirements.
• Records-management expectations.
• Ownership of the signature process.
• Measures for compliance and adoption.

Operative procurement may use electronic approvals and digital acceptance processes in purchase-to-pay activities, but the formal execution of negotiated supplier contracts usually sits primarily within tactical procurement and source-to-contract.

Where this fits in the procurement process

Electronic signature belongs in the negotiation and contracting stage of the sourcing process.

It connects particularly to:

• Final contract preparation.
• Internal review and approval.
• Contract award.
• Signature.
• Contract storage.
• Implementation handover.
• Contract management.

The electronic-signature process should connect to the wider procurement framework rather than operate as an isolated administrative activity.

Frequently asked questions

What is an electronic signature in procurement?

An electronic signature is an electronic method through which a person indicates agreement with a procurement document, such as a supplier contract, amendment, statement of work or commercial agreement.

Are electronic signatures legally binding for procurement contracts?

Electronic signatures are recognised in many jurisdictions, but the answer depends on the document, jurisdiction, signature method and circumstances.

Buyers should not assume that every method is suitable for every contract.

What is the difference between an electronic signature and a digital signature?

Electronic signature is the wider legal and business concept of signing electronically.

A digital signature is a cryptographic method that can support identity verification, document integrity and signature evidence.

What is the difference between an advanced and qualified electronic signature?

An advanced electronic signature must meet eIDAS requirements relating to its connection to the signatory, identification, signatory control and detection of document changes.

A qualified electronic signature adds a qualified certificate and qualified signature-creation device. Under eIDAS, it has the equivalent legal effect of a handwritten signature.

Does electronic signature prove that a supplier representative has signing authority?

Not necessarily.

The signature process may identify the individual, but procurement must separately establish whether the individual is authorised to represent and bind the supplier’s legal entity.

When should procurement require stronger authentication?

Stronger authentication should be considered when the financial, regulatory, operational or dispute risk is higher.

The decision should follow a documented risk-based policy.

Should procurement retain the signature audit trail?

Yes. The organisation should normally retain the signed contract together with the relevant evidence record, certificates, approvals and validation information according to its legal and records-management requirements.

Can international supplier contracts be signed electronically?

Many can, but cross-border contracts require additional care.

The buyer should consider the governing law, location of the parties, document type, recognition of the signature method and any formal national requirements.

Is a scanned handwritten signature an electronic signature?

It may constitute a form of electronic signature, depending on the applicable law and circumstances.

However, a scanned image may provide weaker evidence than a controlled signing workflow with authentication, timestamps and document-integrity controls.

Is electronic signature the final step in procurement?

No.

After signature, the contract must be validated, archived, handed over, implemented and managed.

Conclusion

Electronic signatures can make procurement contracting faster, more transparent and easier to manage.

However, speed should not replace control.

A professional electronic-signature process confirms:

• What was signed.
• Who signed.
• Whether the person had authority.
• Whether the final document remained intact.
• Whether the method was appropriate.
• Whether the evidence can be retained.
• Whether the completed contract entered contract management.

For tactical buyers, electronic signature is therefore not merely a software function. It is part of the governance that turns a sourcing decision into an enforceable, traceable and manageable supplier agreement.

Extra reading: How to source and select an electronic-signature provider

Selecting an electronic-signature provider should be treated as a sourcing project rather than a simple software purchase.

The process should begin with the organisation’s contracts, risks and users—not with provider demonstrations or lists of popular brands.

Start by defining the business need

Document why the organisation is considering a new solution.

Typical needs may include:

• Long contract cycle times.
• Too much manual follow-up.
• Weak contract-version control.
• Limited signing evidence.
• Inconsistent authentication.
• Poor integration with contract storage.
• Difficulty supporting international signatories.
• Lack of a standard company process.
• Existing tools that buyers or suppliers do not use.

Define measurable objectives, such as:

• Reduced time from approval to completed signature.
• Increased use of the approved workflow.
• Fewer incorrectly signed agreements.
• Complete evidence records.
• Automated transfer to the contract repository.
• Improved supplier and user experience.

Form a cross-functional sourcing team

The provider will process contracts, identities, personal data and legally relevant evidence. Procurement should therefore avoid selecting the solution alone.

The project team may include:

• Procurement.
• Legal.
• Information security.
• Data protection.
• IT.
• Records management.
• Contract management.
• Business representatives.
• Internal audit.
• Finance.

Each function should contribute requirements and participate in the risk assessment.

Define the required use cases

Do not evaluate providers against a vague need for “electronic signature.”

Describe the workflows the system must support.

Examples include:

• Standard supplier contracts.
• High-value strategic agreements.
• Contract amendments.
• Statements of work.
• Data-processing agreements.
• Non-disclosure agreements.
• Multi-party agreements.
• International contracts.
• Documents requiring witnesses.
• Internal approval followed by external signature.
• Bulk signing of standard documents.
• Mobile signing.
• Signing by users without platform accounts.

The use cases determine which functions and signature methods are actually necessary.

Create structured requirements

Legal and geographic requirements

Consider:

• Countries and jurisdictions.
• Supported electronic-signature levels.
• Advanced and qualified electronic signatures.
• Qualified certificates.
• Witnessing and notarisation support.
• Cross-border recognition.
• Evidence available for disputes.
• Long-term validation.
• Language support.

For EU-qualified services, verify the provider and the specific qualified service through the official EU/EEA Trusted Lists. Do not rely only on a general marketing statement that the provider is “eIDAS compliant.”

Identity and authentication requirements

Consider:

• Email authentication.
• One-time passcodes.
• Multi-factor authentication.
• Electronic identity services.
• Identity-document checks.
• Bank or national electronic identification.
• Certificate-based authentication.
• Authentication assurance levels.
• Controls preventing unauthorised forwarding.
• Signer access logs.

Identity-proofing and authentication requirements should reflect the risk of the contracts involved. NIST SP 800-63-4 provides an authoritative assurance-based framework that can support this assessment.

Signature and evidence requirements

Consider:

• Simple, advanced and qualified electronic signatures.
• Digital certificates.
• Trusted timestamps.
• Document-integrity controls.
• Audit records.
• Evidence certificates.
• Signature validation.
• Evidence export.
• Long-term verification.
• Independent verification outside the platform.

Workflow requirements

Consider:

• Sequential signing.
• Parallel signing.
• Multiple legal entities.
• Multiple signatories.
• Internal approval.
• External signature.
• Delegation.
• Reminders.
• Expiry dates.
• Reassignment controls.
• Contract templates.
• Signing fields.
• Signing through mobile devices.

Privacy and security requirements

Consider:

• Data-processing agreement.
• Subprocessors.
• Data-storage locations.
• International data transfers.
• Encryption.
• Access control.
• Security logging.
• Incident management.
• Breach notification.
• Data deletion.
• Vulnerability management.
• Independent assurance reports.
• Business continuity.
• Disaster recovery.

When GDPR applies, the agreement should address processor requirements and appropriate technical and organisational security measures.

Integration requirements

Consider integration with:

• E-sourcing.
• Contract lifecycle management.
• Document management.
• Enterprise resource planning.
• Customer relationship management.
• Identity and access management.
• Single sign-on.
• Company directories.
• Archiving systems.
• Workflow automation.
• Reporting tools.

Also assess the provider’s APIs and the ability to transfer documents, metadata and evidence into other systems.

Commercial and service requirements

Consider:

• Pricing per user.
• Pricing per document or transaction.
• External-signer charges.
• Fees for advanced identity checks.
• Qualified-signature fees.
• Storage charges.
• Implementation costs.
• Integration costs.
• Support levels.
• Availability commitments.
• Service credits.
• Training.
• Exit assistance.
• Price-adjustment mechanisms.

Use an RFI, RFP or RFQ appropriate to the market

An RFI can be useful when the organisation needs to understand available signature methods, geographic coverage or integration models.

An RFP is suitable when the need is complex and suppliers must explain their proposed solution, implementation approach and risk controls.

An RFQ may be sufficient when requirements are standardised and the organisation already understands the available solutions.

The sourcing document should provide realistic transaction volumes, countries, user groups, integrations and contract types. Without this information, suppliers cannot provide comparable commercial proposals.

Build a balanced evaluation model

An illustrative evaluation model could be:

• Legal and geographic capability: 20%
• Security and data protection: 20%
• Identity, signature and evidence functionality: 20%
• Workflow and integration: 15%
• User and supplier experience: 10%
• Implementation and support: 10%
• Commercial model and total cost: 5%

The weighting should be adapted to the organisation’s risk and priorities.

Mandatory requirements should be separated from scored requirements.

For example, the ability to meet a required legal signature level or security requirement may be pass/fail rather than something a supplier can compensate for through a lower price.

Test the solution with real scenarios

A scripted demonstration is more useful than a general sales presentation.

Ask shortlisted providers to demonstrate realistic workflows, such as:

1. A standard domestic supplier agreement.
2. A cross-border contract requiring stronger identification.
3. A contract with two internal approvers and two supplier signatories.
4. An amendment linked to an existing agreement.
5. Export and independent storage of the signed document and evidence.
6. Validation of a signature several years after completion.
7. Migration or retrieval after the subscription has ended.

The pilot should include buyers, administrators, signatories, suppliers, IT and legal users where relevant.

Evaluate not only whether the workflow works, but also whether ordinary users understand it.

Complete supplier due diligence

Before award, review:

• Company ownership and financial stability.
• Information-security controls.
• Data-protection arrangements.
• Subprocessors.
• Service availability.
• Business continuity.
• Incident history.
• Insurance.
• Regulatory status.
• Qualified trust service status where relevant.
• Product roadmap.
• Customer references.
• Exit and portability arrangements.

Contract for the full service lifecycle

The supplier contract should address:

• Scope and service description.
• Availability and support.
• Security obligations.
• Personal-data processing.
• Subprocessor changes.
• Incident and breach notification.
• Evidence retention.
• Data ownership.
• Audit rights.
• Regulatory cooperation.
• Business continuity.
• Change control.
• Price adjustments.
• Termination assistance.
• Data and document export.
• Secure deletion.
• Continued validation of existing signatures.
• Exit and migration.

The contract should also define what happens to signed documents, evidence records and validation services when the agreement with the provider ends.

Plan implementation before award

Provider selection creates no value unless the organisation establishes a usable process.

The implementation plan should cover:

• Contract categories included in the rollout.
• Signature-risk policy.
• Roles and responsibilities.
• Approval workflows.
• System integration.
• Contract templates.
• User access.
• Training.
• Supplier communication.
• Helpdesk support.
• Records management.
• Reporting.
• Adoption measures.
• Continuous improvement.

The related LHTS article on selecting an e-sourcing provider emphasises that adoption and process design matter more than simply comparing provider lists. The same principle applies to electronic signatures.

Measure both usage and control quality after implementation.

Useful measures may include:

• Percentage of eligible contracts signed through the approved platform.
• Average time from approval to signature.
