Frequently asked questions

The evaluation schedule depends on security review, legal scope, integrations, procurement gates, and POC complexity. Agree on evidence requirements and test scenarios first, then set milestones from that plan.

ISO 27001 RFC 3161 21 CFR Part 11

Compliance standards and certifications change over time. Verify each vendor's current trust-centre report, certificate scope, audit period and product-specific controls before purchase. eSign.AI claims in this page should be confirmed against current product documentation.

Vendor scorecard with evidence

A score is useful only when each point has an owner and proof. Use the same workflow for every vendor and record pass, hold or reject instead of filling unknowns with assumptions.

	Area	Proof to keep
Legal and market route	Written route for the target document and market	Current legal/product source and test record
Signing and evidence	Signer journey and retrievable completed record	Exported sample evidence package
Integration	API, webhook and failure handling	Proof-of-concept result and owner
Commercial scope	Users, volume, support, implementation and retention	Dated quote and exclusions

How eSign.AI should be evaluated

Use eSign.AI as a candidate when its tested signing workflow meets the buyer's written acceptance criteria. The recommendation should name the tested document, market, integration, evidence result and remaining risks.
