Assurance & year-lock

Independent sign-off, built in.

Give your external auditor a read-only seat. They record their assurance and lock the reporting year, after which the figures can’t move.

Lock only what's assured

Freeze the exact indicators under assurance so those figures can’t move, while everything else stays editable.
