Two ways to bring your books across
Most companies switch with a snapshot of their books and keep working without a break. If you want your full history inside Mast, our team migrates it for you.
Start with a snapshot
Do it yourself in minutes. The setup wizard guides you through your chart of accounts, opening balances, open invoices, and master data, and you work in Mast from day one.
- Trial balance and open items, guided by the setup wizard
- Open invoices and bills carry over, so payment matching keeps working
- Customers, suppliers, and products imported via Excel
Full-history migration
Our team transfers your complete posted history into Mast, original documents included, from Bexio, Abacus, WinBIZ, Banana, Crésus, and others. A paid service, scoped with you before anything moves.
- Your posted years, carried over entry by entry
- Original documents included: PDFs, receipts, attachments
- Bank transaction history as an optional add-on
In both cases, your previous system remains the legal archive for the periods booked there. Keep it accessible for the legal retention period; from cutover on, the work happens in Mast.
