Sent over the Pactivo API — signers finish on a hosted page, no account needed.

The signature is the easy part. The proof is what your file needs.

No more chasing

A signer signs on their phone in seconds. Automatic reminders mean you stop being the chaser.

Proof you can hand over

Each letter seals into a PDF carrying a PAdES digital signature and an RFC-3161 timestamp — evidence a reviewer can check, not take on trust.

Audit that files itself

Every letter carries a sealed, shareable trail — no folder of PDFs, no “where did we save that”.

What good looks like

Engagement letters used to sit unsigned for a fortnight. Now they come back the same afternoon, with the sealed trail already attached.

Close your engagement letters faster.
