The contract is the link.
The signature comes back as one.
Fill in an invoice, a quote or an agreement and send it as a link. Whoever signs does it in their browser and sends a link back. Your browser checks it against the exact document you sent, then puts the signed PDF together. No account, no server, nothing stored anywhere but here.
Fill it in
Invoices, quotes, a mutual NDA, a services agreement, an offer letter, receipts, sign-offs, releases and change orders. Formulas add up the money.
Send the link
The whole document travels inside the link, and each signer gets their own.
They sign in their browser
Their browser redraws the document and checks it matches yours before they can sign.
Keep the proof
The signed PDF ends with a certificate and carries its own evidence, checkable by anyone.
