Signed invoice in the app

Updated 07.10.2026

Once the customer signs, the invoice is marked as signed and locked in AdBooks. In this guide, you see where the signatures and the signing trail are.

1. Signed invoice in the list

  1. In the invoice list, the signed invoice is labeled as signed and locked.
  2. Click More next to the invoice, then Preview.

2. Locked document

  1. At the top, it says the customer signed the document and that it is locked.
  2. A signed invoice can no longer be edited.

3. Signatures and signing trail

  1. At the bottom of the invoice are the issuer's and the customer's signatures, with the date and time of signing.
  2. The Signature audit trail records every step: link, view, code and signature.
  3. Done. You can now collect payment for the signed invoice.
