Digital Signature On Invoice

Customers often need to acknowledge an invoice. This module adds a signature field to invoices and vendor bills so the signer can draw it on screen. The signer name and time are saved next to it. Accountants and sales staff use it with the Invoicing app. It replaces paper acknowledgements with an electronic record.

   Open the signature tab

   The invoice form shows a Customer Signature tab, and a Vendor Signature tab on bills. The user opens the tab that matches the document type. It is available on posted and draft documents.
