What this does

Opening balances are a dated set of balances, usually from your prior trial balance on the conversion date. Open customer invoices and vendor bills should be entered individually so they can be paid and aged.

Any difference posts to Opening balance equity, which should be zero (or moved to retained earnings) once everything is entered.

Before you start

  • Get a trial balance, AR aging, and AP aging from your old system as of the conversion date.
  • Pick a conversion date — usually a month or year end.
