A quick walkthrough of how ctSignature™ handles document upload, field placement, signing, and the audit trail.
Everything you need to start sending today.
A complete signing app — not a toolkit you have to assemble. Sign up, upload a PDF, place fields, and send.
Visual field placement
Drag-and-drop signature, initials, name, date, and stamp fields onto any PDF. No code required.
Reusable templates
Set up a document once and reuse the layout for any recipient — perfect for repeatable contracts.
Multi-signer workflows
Independent signing orders and per-signer field assignments. Sequential, parallel, or hybrid.
Tamper-evident audit trail
Cryptographic document hashing and per-action audit logs — proof that what was signed hasn't changed.
ESIGN / UETA-aligned
Signing workflows designed for ESIGN/UETA — consent capture, signer intent, audit trail, and retainable signed records.
Your brand, not ours
White-label sender brand on signing pages and email notifications. Strict multi-tenant data isolation.
Two ways to pay. Pick what fits your volume.
A monthly subscription if you send documents regularly and want team access. Prepaid credit packs if you only sign occasionally and it's just you. Either way, the same product.
- You send documents on a steady, predictable cadence.
- You need more than one user on the account.
- You want webhooks, templates, or embedded signing.
- Your effective cost per document drops faster with volume.
- It's just you on the account.
- You sign documents occasionally, not every week.
- You don't want a recurring subscription.
- You'd rather pay once and use credits over time.
