Reversal vs reversing entry

A reversal is a new entry that cancels a posted entry that was wrong, leaving both in the ledger; a reversing entry is a planned reversal of a month-end accrual on the first day of the next period, so the real bill can be booked normally.

Each, defined

Reversal

An offsetting entry that undoes a posted entry.

Reversal in the glossary

Reversing entry

An entry dated the first day of the next period that exactly offsets a period-end accrual, so the real invoice can be coded normally without double-counting.

How they relate

Posted entries are never edited or deleted. When one is wrong, a reversal posts the same lines on opposite sides, dated in an open period, and the correction follows. The audit trail keeps all three.

A reversing entry is not a correction. It is part of the accrual routine: the month-end estimate is undone on day one so the vendor's invoice can be entered without double-counting.

Questions

Why reverse instead of editing?
Because posted entries are evidence. Editing one destroys the record of what the books said when they were reported.
Are all adjusting entries reversed?
Usually not. Depreciation and prepaid releases follow a schedule and are not reversed.
