Client Signs via Email Code
Your client opens a secure link, enters a 6-digit code sent to their email to verify identity, and signs.

Both parties receive the stamped PDF, an official Certificate of Completion, and a private verification link.
Why pay monthly for tools you rarely open?
Most independent professionals, freelancers, and small businesses sign occasional agreements. SignProof delivers airtight legal evidence with zero monthly commitments.
Stop the monthly subscription drain
Pay only when you have a contract to seal
Mainstream e-signature providers charge $30 to $50 every month. If you only sign six documents a year, that totals $360 annually—that is $60 per signature.
Purchase credits once and use them whenever needed. Credits never expire.
If a signer declines or a request expires unsigned, your credit returns immediately to your balance.
Real evidence, not just an image
Legal audit packages that stand up to scrutiny
Basic tools merely stamp a PNG image of cursive text onto a document. In a dispute, they offer little proof of identity or evidence that the text was not edited afterward.
Signers must verify control of their inbox with a six digit challenge code prior to signing.
Every completion produces an unalterable certificate. Any post signing modification breaks the seal immediately.

Frequently asked questions
Straightforward answers regarding legal validity, cryptographic evidence, and credit economics.
Do you offer custom plans for teams or high volume?
Yes. Email [email protected] with your expected monthly volume and we will set up a custom plan. You receive a redeem code that adds the agreed credits to your account from Settings.
Are SignProof signatures legally binding?
Yes. SignProof creates legally binding electronic signatures recognized under the US ESIGN Act, UETA, and European Union eIDAS regulations. Every signed agreement includes confirmed signer email identity, precise UTC timestamps, a full audit trail, and a cryptographic tamper evident seal.
Do clients need to create an account or download an app?
No. Your clients never need to install software or register for an account. They simply click the secure link in their email, enter a six digit access code sent to their inbox to confirm their identity, and sign directly in their browser on any device.
Do purchased signature credits ever expire?
No. Purchased credits remain in your account permanently until you use them. There are no monthly resets, no annual expirations, and no recurring charges.
What happens if a signer declines or does not sign?
You never lose a credit on an uncompleted agreement. When you send a signature request, 1 credit is temporarily reserved. If the signer declines, if you cancel the request, or if it expires unsigned, your credit is automatically refunded to your balance.
How does third party verification work?
Every completed agreement includes a Certificate of Completion with a unique verification link. Anyone holding the document (such as clients, banks, or legal counsel) can verify its exact authenticity online without needing an account or software.
How do I verify a signed PDF?
Use our free PDF verifier — no account needed. Go to Verify PDF in the app header (or Free PDF verifier in the footer), upload the PDF, and we'll check its SHA-256 fingerprint against the original signing record to confirm it's the exact file that was signed and hasn't been altered. Your file is hashed in memory and never stored.
Why is pay as you go better than a monthly subscription?
Most independent professionals and small businesses only send a few contracts each quarter. Paying $30 to $50 every month means wasting hundreds of dollars on idle software. With SignProof, you pay only for what you actually use with zero monthly overhead.
