What QuickBooks is good at
QuickBooks is a long-established SMB accounting platform with US origins and a broad global footprint. It is mature in the things you would expect of a multi-decade accounting tool: a wide chart of accounts, payroll add-ons in markets it serves natively, an ecosystem of integrations, and recognition from accountants who have used it for years.
For businesses already running on QuickBooks — particularly those with operations or accountants outside of South Africa — it is a perfectly reasonable place to keep the books.
