From your accountant account, you can easily link your entrepreneurs' Billit client files with Visual Books and import your client files into your accounting software at fixed times (or whenever you want). Visual Books correctly reads the UBL invoices that Billit imports, and you can easily process them in Visual Books.
To connect Billit to Visual Books, you need the BillSync application. BillSync makes sure the documents end up in the right place on your computer/server.
