Choose the migration boundary before exporting anything
Decide the last date the old ledger will be authoritative and the first date the new system will accept live transactions. A clean month-end or year-end can simplify the cutover, but operational needs may require a midyear move.
Document who can post to the old system during transition. Two active ledgers create duplicate entries quickly.
Preserve both balances and detail
Export the chart of accounts, trial balances, general ledger, customer and vendor lists, open invoices, open bills, fixed assets, payroll support, bank reconciliations, tax reports, attachments, and any custom dimensions used for management reporting.
Do not assume a summary opening balance is enough if the business needs historical customer, vendor, project, department, or tax detail later.
Validate the new ledger before going live
Compare the old and new balance sheets and profit and loss statements at the cutoff date. Reconcile cash, receivables, payables, debt, equity, payroll liabilities, and tax balances independently.
Test one customer invoice, vendor bill, bank feed, payment, payroll journal, and reporting workflow before the team starts normal operations.
Archive the old system deliberately
Keep read-only exports and source documents even if the old subscription is cancelled. Record how long portal access will remain available and who owns the archive.
A good migration ends with a signed reconciliation showing that the new opening position matches the old closing position. That record is what lets future accountants trust the conversion.
Questions buyers usually ask
What is the best time to switch accounting software?
A month-end or year-end can simplify the cutoff, but the best date is one the business can control operationally while preserving a clear old-system closing balance and new-system opening balance.
Should historical transactions be migrated or only opening balances?
It depends on reporting and audit needs. Some companies can use opening balances plus a permanent archive, while others need transaction-level history, customer detail, vendor detail, or project dimensions in the new system.

Contact InstitutionSmall-business bookkeeping is the system that turns sales, expenses, payroll, debt, taxes, and owner activity into reliable financial statements. Here is how to build it so the books remain useful all year, not only at tax time.
A month-end close turns a live transaction feed into reviewed financial statements. This 10-step workflow covers transaction cutoff, reconciliations, payroll, receivables, debt, adjustments, analytical review, and a clean final reporting package.
A reliable monthly close is not a pile of categorized transactions. It is a repeatable process that reconciles source accounts, resolves exceptions, reviews the balance sheet, publishes statements, and gives operators a stable version of the month.
