Features
A single dashboard for sending agreements, tracking signatures, and storing signed copies — built for the people who actually do the work.
Click the field, drop it on the page. Signatures, initials, dates, text. If you can use email, you can use ctSignature.
Set up your standard NDA, contract, or onboarding form once. Reuse it forever — just change the recipient.
Send to one person or a chain of ten. Sequential or all-at-once, with per-recipient fields and live status.
We email the signer the link, nudge them if they forget, and notify you the moment they sign. You don't lift a finger.
Your logo, your colors, your name on the signing page. Recipients see your business — ctSignature stays out of the way.
Every view, click, and signature time-stamped with IP, device, and a tamper-proof hash. Pull it as a PDF whenever you need it.
How it works
Drop any PDF onto the dashboard. Sign agreements, NDAs, offer letters, lease addenda — whatever you've got.
Drag fields onto the document — signatures, initials, dates, text. One recipient or many.
Recipients sign in their browser — no account needed. You get an email and a signed PDF the moment they're done.

Security
Every signature is bound to its document with a cryptographic hash, captured against an immutable audit log, and protected by tenant-scoped access control.
A clean REST API, signed webhooks, and embedded signing are included on Pro and Enterprise — for the day someone wants to wire ctSignature into your CRM or app. Most customers never touch them. That's fine too.
