Getting a document signed electronically

Compaxit lets you send any PDF to someone to sign online, and gives you back a signed copy with a completion certificate. It is separate from filing anything at Companies House — this is your own document signing, for things like a shareholders’ agreement, an NDA or a letter of engagement.

Two ways to sign

You can either hold a person’s signature once and reuse it whenever you produce that company’s documents, or send a specific document out to be read and signed. Both live on a company’s Signatures tab.

Sending a document for signature

• Upload the PDF and give it a title, then choose who signs — anyone on the register, or a name you enter.
• Share the secure link or QR code with the signatory. It is one-time and expires after 14 days; no account is needed.
• The signatory opens the link, reads the document on screen, confirms they have read it, and signs — drawn with a finger or mouse, or typed.

What you get back

Once signed, the request is marked received and a signed PDF becomes available to download. It is the original document with a completion certificate appended, recording the signatory, their capacity, the date and time (in UTC), the signer’s IP address and a document fingerprint (SHA-256) that binds the certificate to the exact file that was signed. Every request stays listed on the Signatures tab, so you can retrieve the signed copy at any time.
