Manager.io alternatives: reconcile the books with an accountant

For Manager.io alternatives, use synthetic but realistic records and seek qualified local accounting review.

• Import accounts, contacts, opening balances, invoices, and payments.
• Test partial payments, credit notes, inventory if used, and period closing.
• Reconcile trial balance, receivables, tax reports, and currencies.
• Check permissions, audit history, backup, and export.
• Run parallel records before making a new system authoritative.

A similar invoice screen cannot establish accounting correctness. Every balance difference needs an explanation before cutover.
