How a contract moves through ZSign
Every contract follows a clear path with full visibility at each stage.
Draft
Write or import your contract. Use templates for NDAs, service agreements, and employment contracts. Add dynamic variables that auto-fill per recipient.
Review
Share the draft with internal stakeholders. Reviewers can comment and suggest changes directly in the document before it goes out.
Approve
Route the contract through sequential or parallel approval chains. Legal, finance, or management sign off with one click. You see exactly where it sits in the pipeline.
Send for signature
Once approved, send the contract to external signers. Each recipient gets a unique link by email. Set expiration dates and automatic reminders.
Sign and archive
Signers review and sign from any device — no account needed. The signed PDF with embedded signatures and a full audit trail is available immediately.
Built for contract operations
Draft, approve, sign, and archive — without leaving ZSign.
Contract templates
Start from NDAs, service agreements, employment contracts, and more. Save your own as reusable templates.
Approval workflows
Sequential or parallel approval chains. Approvers get email notifications with one-click approve or reject.
Audit trail
Every action is logged with timestamps, IP addresses, and device info. Export the full trail as a PDF certificate.
Expiration and reminders
Set contract expiration dates and automatic reminder sequences so nothing goes unsigned.
Document integrity
Contracts are hashed at the time of signing. Any post-signature tampering is detectable.
Compliance
ESIGN Act and UETA compliant in the US. eIDAS Basic Electronic Signature in the EU. Every signature carries the same legal standing as pen on paper.
Cryptographically defensible, not just “logged”
Most e-sign tools log events. We chain them. Every audit-log row carries a SHA-256 hash linked to the previous row — removing or modifying any past event breaks the chain visibly. The signed PDF's bytes are also hashed at delivery and re-verified nightly to catch silent corruption. When counsel asks for the file, you hand them an evidence bundle that survives discovery.
- SHA-256 hash chain across every audit event — tampering is detectable, not just suspected
- IP, device, user-agent, and ERCD consent version captured at each step
- Final signed-PDF bytes hashed at delivery, re-verified nightly for bit-rot
- 7-year compliance archive (WORM Object Lock) — no one can delete or overwrite
- Byte-deterministic evidence-export bundle: manifest + audit-log JSONL + Certificate of Completion
