When a signature is captured onto an invoice, it is stored in System Five.
To see the saved signatures in a specific invoice, you just need to open the invoice, click on the options button at the top of the screen and select View Document Signatures.
Here you can view all captured signatures or reprint a copy of the invoice with the relevant signature.
If the invoice was changed and re-printed, there should be more than one signature saved, and they can be viewed and re-printed from here.
To reprint the invoice you will need to select the invoice with the correct signature or date, then click the View button.
This will open the saved invoice with the captured signature in a PDF format, then you can reprint the invoice from the PDF.
