All invoices that have been exported to the accounting system can be found in a single list of exported invoices. From this list you can also move invoices back to the "to be exported list" if necessary, to re-export them to the accounting system.
1. Open the Export submenu of the Invoicing module to find the list of exported invoices. Here you can do the following:
View the exported invoices.
Restore an exported invoice to the list of "to be exported invoices".
2. Invoices that return to the export list can then be exported.
