Simple signing. Cryptographic proof.

Your customers sign straight from an email, verified on their phone. Every contract is sealed with a timestamp and a SHA-256 fingerprint.

Sign is part of Nurion Work: €39 per person per month, with Mail, Chat, Drive, Docs, Sheet and Board.

It automatically finds where to sign.

Upload any PDF. Sign finds the signature lines, the place and date lines and the parties named in the contract, and suggests who signs where. You check it and save it as a template.

You set the order.

Put every party on one contract, in the order you choose. Each signer gets their link by email or text message as soon as the one before has signed, and you always see who is still due. At the end, one sealed contract covers everyone.

Simple, or with an ID.

Most contracts need only a code. When you must know exactly who signed, the signer also uploads a photo of their identity document.

Your agent can start it too.

Ask the agent you connect to send a contract and it does the rest: picks the template, adds the signers in order, sends the links and tells you when the last signature is in.
