Banana Accounting is judged by whether books remain correct and usable, not by the number of dashboard cards. Choose a closed test period with opening balances, invoices, adjustments, and the reports your accountant signs off. Enter or import the same transactions into a candidate and reconcile totals account by account.
Inspect tax codes, currencies, attachments, audit trail, and the ability to correct a mistake without obscuring the original entry. Export both the transaction data and final reports for archival use. Before switching an active business, confirm local reporting requirements with your accountant and plan a clean period boundary for the cutover.
