How invoices reach SignSolid: inbox scanning, forwarding, upload, and supplier portals

Capturing invoices

What SignSolid looks for in your connected mailbox, and what it ignores.

How inbox scanning works

Every workspace gets its own address. Anything you send it becomes an invoice.

Forward invoices to your capture address

Add an invoice yourself. SignSolid reads and files it just like an emailed one.

Upload an invoice manually

SignSolid processed the invoice but was not confident about a field, so it is asking you.
