Pre-Migration Checklist

  • Reconcile all bank accounts up to the conversion date
  • Lodge all outstanding BAS and IAS returns
  • Finalise and lodge STP report for the current pay period
  • Export key reports (P&L, Balance Sheet, Trial Balance) as PDFs
  • Back up your data to an external drive and cloud storage
  • Notify your BAS agent or bookkeeper about the planned switch date
Caution: Mid-Year Migration & STP ImplicationsSwitching software mid-financial year introduces risk around Single Touch Payroll (STP) reporting. If you migrate between 1 Jul and 30 Jun, you must finalise an STP event in your old system before cutting over, then lodge a “Year to Date” event in the new system with carried-forward figures.
