This is complex. In May client had a QB challenge and several previously written checks were missing from the system. We thought we had identified them all. However, there was one $8300 check is written monthly and the fact that one was missing did not come into light until July bank reconciliation. Each month the amount was reconciled not coordinating with the check number. With a closer look it became clear that check 8184 was not in the register. A bill was set to pay with that check number. The vendor does not show in the A/P aging detail as outstanding. Cash is overstated though as I have an unmatched bank transaction. I need to credit cash, but I am unclear what to debit. A debit to accounts payable will cause AP to be out of balance. Any experience on how to rectify would be greatly appreciated.
