Contracts that look like contracts.

Page numbers, dotted signature lines, audit-hash stamps, versioning, status chips — the chrome of paperwork made digital. The aesthetic is the value prop. Sales teams who send these look credible to the buyer on the other side of the contract.

The pieces, load-bearing.

No bento grids. Read one, then the next.

Write contracts in ZSign.

A real document editor — not a PDF uploader. Templates, variables, conditional clauses, pricing tables. Paste from Word or Google Docs and the formatting actually survives — heading styles, lists, even nested numbering. Most e-sign editors mangle it.

Track every open, every signature.

Per-recipient tracking links, time-on-page, scroll depth on long contracts, and a full audit trail. You'll know your contract is being read before you follow up.

ZSign tracking and analytics
Tracking

Sign on a phone, in a browser.

Most signers are on mobile. Large touch targets, fullscreen signature pad with undo, iPhone safe-area aware, the right soft keyboard for every field. No app install. No account. No zoom dance.

Defensible, not just logged.

Every audit-log row carries a SHA-256 hash linked to the previous row — removing or modifying any past event breaks the chain. Final signed-PDF bytes are re-verified nightly to catch silent corruption. 7-year compliance archive in WORM-mode storage. The evidence bundle is what your counsel asks for in discovery.
