What is

What is e-signature software?

Drag-and-drop fields, route signers, court-enforceable certificates.

E-signature software is a SaaS tool that lets users drag signature fields onto a document, route through one or more signers, collect signatures from a browser, and attach a tamper-evident certificate.

Definition

e-signature software

E-signature software lets senders drag signature fields onto a document, route through signers (sequential, parallel, or in-person), collect signatures from any browser, and attach a tamper-evident certificate of completion. Court-enforceable under eIDAS (EU), ESIGN and UETA (US), and 21 CFR Part 11 (life sciences).

What it is

The core elements.

Drag-drop fields (signature, initial, date, text, checkbox, radio).
Sequential, parallel, or in-person routing modes.
Email + magic-link signer flow — no account required.
Tamper-evident certificate with name, email, IP, device, consent timestamp, doc hash.
Templates with variables and conditional clauses for bulk send.

Why it matters

What changes when you use it.

Court-enforceable signatures with audit trail.
Faster cycle times — sign in 30 seconds instead of mailing.
Routing automation — no manual hand-offs between signers.
Compliance — eIDAS, ESIGN, UETA, 21 CFR Part 11.

How it works

In a typical workflow.

Upload a PDF.
Drag signature, initial, date, and text fields onto each page.
Add signers in the order they should sign.
Send — each signer gets an email with a sign link.
Done envelope returns with certificate of completion attached.

Common questions

About e-signature software

Is e-signature software legally binding?

Yes, in most jurisdictions. eIDAS (EU), ESIGN and UETA (US), 21 CFR Part 11 (life sciences) — all recognize properly-implemented e-signatures as binding.

Can recipients sign without an account?

Yes. Standard flow uses a magic link from email — recipient clicks, signs in their browser, no account needed.

What about bulk send?

Use a template with variables, upload a CSV with one row per recipient. Each signer gets their own envelope and audit trail.
