Enterprise eSignature Vendor Evaluation Checklist

How to use this checklist

This checklist covers the critical evaluation areas for enterprise e-signature platforms. Use it to create a structured RFP or to compare shortlisted vendors side by side. Assign weights based on your priorities.

SOC 2 Type II attestation
Data residency options for required regions
Encryption at rest and in transit (AES-256, TLS 1.2+)
Private key stored in HSM (FIPS 140-2 Level 3+)
Penetration test reports available (annually)
GDPR / PIPL / CCPA compliance documented
Industry-specific: HIPAA, PCI DSS if needed

Signature and identity

SES, AES, QES all available
QES coverage in all operating jurisdictions
eKYC (document + selfie) support
National eID integration (Singpass, iAM Smart, etc.)
Qualified electronic seal (QSeal) support
Trusted timestamping (RFC 3161) included
LTV / PAdES LT or LTA support
Configurable signature tier per document type

API and automation

REST API with comprehensive endpoints
Webhook notifications for real-time status
Bulk send (1000+ envelopes per batch)
Template management with merge fields
Conditional routing based on data fields
Rate limits adequate for your volume
SDKs in your preferred languages
Sandbox / test environment available

User experience and support

Signer UI in all required languages
Mobile-optimised signing flow
Offline signing capability (if needed)
Dashboard with envelope status tracking
Bulk download of signed documents
24/7 support or adequate coverage hours
Dedicated account manager (enterprise)
Implementation services available

Where eSign.AI fits

Against this checklist, eSign.AI scores 2/2 on: ISO 27001, SOC 2, HSM-protected keys, SES/AES/QES support, national eID integration (6+ APAC countries), trusted timestamping, PAdES B-LT, REST API with webhooks, bulk send, template management, conditional routing, 16-language UI, and mobile signing. Data residency covers China (PIPL), Singapore (ASEAN), and EU (eIDAS). For APAC-focused enterprises, eSign.AI fills the compliance gaps that global-only platforms leave open.

Vendor evaluation scorecard: weighted scoring template

Use this weighted scoring framework to compare vendors objectively.

Compliance weight (30%)

ISO 27001 (3 pts), SOC 2 Type II (3 pts), eIDAS QTSP partnership (3 pts), APAC CA partnerships per country (1 pt each, max 8), China PIPL data residency (3 pts), 21 CFR Part 11 validation (2 pts). Maximum compliance score: 22 pts. Weight: 30% of total.

Integration weight (25%)

REST API (2 pts), webhook reliability (3 pts), HRIS connectors (2 pts each, max 6), CRM connectors (2 pts each, max 4), ERP connectors (2 pts each, max 4), SSO protocols supported (1 pt each: SAML, OIDC, SCIM). Maximum integration score: 21 pts. Weight: 25% of total.

Scalability weight (20%)

Max envelopes per bulk batch (1 pt per 1,000), API rate limit (1 pt per 500/hour), data residency regions (3 pts each, max 12), signer language coverage (1 pt per language, max 16), uptime SLA (5 pts for 99.9%, 10 pts for 99.99%). Maximum scalability score: varies.

Frequently asked questions

The evaluation schedule depends on security review, legal scope, integrations, procurement gates, and POC complexity. Set milestones only after the evaluation team agrees on evidence requirements and test scenarios.

How to verify the decision before purchase

Treat comparison claims as dated evidence, not permanent product facts. Use the same test cases and commercial assumptions for every shortlisted vendor.

Request documentary evidence

Collect current product documentation, trust-centre reports, hosting and subprocessor details, API limits, certificate-provider information, and a written list of included and excluded capabilities.

Run representative transactions

Test the required countries, signer identities, document types, failure paths, audit export, independent signature validation, webhook retries, and administrator controls with production-like samples.

Compare a dated three-year TCO

Model the same seats, envelopes, identity checks, certificate transactions, storage, API volume, support, implementation, renewal terms, and exit costs. Record the quote and review date.
