Electronic signature with the evidence around it: documents are sent as envelopes, signed in a tracked session, and sealed with a certificate of completion that stands up in a dispute.
Do not build this if a contract's enforceability matters to you. What you are paying for is not the signing flow — it is that the audit trail, the certificate handling and the identity checks have been through legal review in many jurisdictions, and that the company will stand behind them if a signature is challenged. That standing is the product. WHEN TO KEEP PAYING - Contracts of real value, or anything a lawyer would want to defend - Customers or regulators who ask which standard your signatures meet - Qualified electronic signatures in the EU, which require a certified trust service provider — you cannot self-certify into that category WHEN TO BUILD - Internal approvals, low-value agreements, and anything where a clear record is enough. The full shape is covered under Documenso and SignWell elsewhere in this catalogue WHAT MATTERS IF YOU DO BUILD IT - **An append-only audit trail**: created, sent, delivered, opened, each page viewed, each field completed, signed, declined, downloaded — each with a UTC timestamp, a salted address hash and a coarse user agent. Enforced by a trigger, never edited - The trail rendered as a page appended to the finished document, with the hash of what each person actually saw. A signature without that page is a picture of a name - A document-level digital signature so any later change is detectable, with a timestamp from an RFC 3161 authority so it stays verifiable after the certificate expires - Long random tokens per recipient, no accounts, and optional extra authentication with the method recorded - Backups covering the documents as well as the database, with a tested restore. Losing a signed contract is not an outage, it is a loss THE SENTENCE TO KEEP Write in your README that this proves the document has not changed since sealing and records who did what and when — and that whether it satisfies a particular law in a particular country is a question for a lawyer. Do not let that sentence be removed later. THE ONE-LINE VERSION Build it for internal paperwork. Buy it for anything you might have to defend.
What you lose
- An audit trail that holds up in a dispute: identity checks, timestamps, IP records and a certificate of completion
- Compliance with eIDAS and the ESIGN Act, evidenced rather than asserted
- Qualified and advanced electronic signatures where the law requires them
- Long-term validation, so a signature is still verifiable a decade later
- The fact that the other side already trusts the envelope when it arrives
If you would rather not build
- SignWell — paid, cheaper, similar scope for small teams

Why this verdict
our own opinion · changed only by a person
18/100
Verdict no at 18: stamping a PDF is easy and the evidence chain is buildable, but the product is legal standing, not software. If a signature is ever disputed, what matters is whose certificate sealed it and whether the process meets the standard — and that is bought, not coded.
