From your accountant account, you can easily link your entrepreneurs' Billit client files with Winbooks and import your client files into your accounting software at fixed times (or whenever you want). You can easily add client files to Billit by importing them from Winbooks. If your entrepreneurs have linked their bank accounts to Billit via Billbank or KBC, you can also have the CODA files from their client files imported into Winbooks. Winbooks correctly reads the UBL invoices that Billit imports (via Virtual Invoice), and you can easily process them in Winbooks.
To connect Billit to Wings, you need the BillSync application. BillSync makes sure the documents end up in the right place on your computer/server.
