There are two ways of how you can start receiving e-invoices.
1) To receive an e-invoice from the other company within PayTraq, you can use PayTraq Direct. In this case both you and your supplier should be using PayTraq
2) To receive an e-invoice from the other company outside PayTraq, you can use the integration with one of e-invoice operators. In this case your supplier can be using any other accounting program.
All e-invoices will be delivered directly into your Purchase Inbox.
