Send documents. Get signatures. Track everything.
One tool for writing, sending, signing, and tracking documents.
E-Signatures
Collect legally-binding signatures from anyone, on any device. Signers don't need a ZSign account.
- Signers draw, type, or upload their signature — whatever they prefer
- Add multiple signers and control who signs first
- Send the same document to dozens of recipients at once
- Unsigned documents get automatic reminders so you don't have to chase
- Every signature is backed by a full audit trail: timestamps, IPs, and devices
Document Editor
Write proposals, contracts, and agreements directly in ZSign. No need to draft somewhere else and upload a PDF.
- Format with headings, lists, bold, italic, and inline code
- Drop in tables, images, pricing tables, and content blocks wherever you need them
- Use variables like {{client.name}} that auto-fill for each recipient
- Drag signature, date, and form fields exactly where they belong
- Let AI write the first draft so you can focus on editing
- Track changes and version history so you can review every edit
Templates
Skip the blank page. Pick a template, tweak it, or let AI generate one from a short description.
- Pick from 37+ templates for contracts, NDAs, proposals, invoices, and more
- Turn any document you write into a reusable template
- Describe what you need and let AI generate a template for you
- Variables auto-fill from your contact data — no copy-pasting
Workflows
Automate the steps between drafting and signing so nothing falls through the cracks.
- Require internal sign-off before the document goes to your client
- Set a reminder schedule and stop manually following up
- Documents expire on the date you choose, with optional auto-void
- Control whether signers go in sequence or sign in parallel
Analytics
See what happens after you hit send. Track opens, views, and completions across all your documents.
- Get notified the moment someone opens or signs your document
- See which sections your recipient spent the most time reading
- Track your team's completion rates and average turnaround time
- Export to CSV or push events to your CRM via webhooks
In-Document Payments
Collect payments right inside the document your client is signing. No separate invoice needed.
- Add a payment block to any document — clients pay when they sign
- Powered by Stripe: credit cards, debit cards, and more
- Set fixed amounts or let clients choose from pricing options
- Payment confirmation is recorded in the document's audit trail
PDF Upload & Overlay
Already have a PDF? Upload it and add signature fields, form fields, and text on top.
- Upload any PDF and place signature fields exactly where you need them
- Add text fields, checkboxes, date pickers, and dropdowns over your PDF
- Completed documents download as a signed PDF with embedded audit trail
- Or skip the PDF entirely and write natively in ZSign's editor
