Pending/Aged Payables
If possible, process the checks for any posted payables in the old system in the month prior to the Go-Live date. If this is not possible, manually post any pending Payables into the Orion database as new payables. If you want to age the payables properly, post them in the periods/dates from your old system aging report. After posting pending Payables into Orion, be sure to delete them from the old accounting system PRIOR to entering the beginning balances.
Do NOT bring beginning balance to the control A/P account for Orion. Either payout all aged payables in prior system, or repost the ones that you want to continue aging as new payables in Orion with appropriate periods and dates and adjust the Old Trial Balance accordingly.
