Month-End Close
Month-end close is the routine of reconciling every bank account, categorizing everything still uncategorized, reviewing the profit and loss statement, and then locking the period through its last day.
In short
Reconcile, categorize, review, lock — in that order. Doing this every month, right when statements arrive, is what keeps a discrepancy a two-minute fix instead of something buried under a hundred later transactions.
Also called: monthly close, month end
Month-end close is the name for the routine performed at the end of an accounting period, ending in that period being locked. It is a sequence rather than an action, and the term refers to the whole sequence, not to the lock at the end of it.
The order is the substance of the concept. Verification comes before sealing: the accounts are reconciled and everything outstanding is categorized while corrections are still cheap, and only then is the period closed. Reversing that order is not a variation on the routine, it defeats it — a lock applied to numbers nobody checked seals in whatever was wrong.
It is a discipline rather than a requirement. Nothing forces a close, and books that are never locked still produce correct reports. What locking buys is that a figure already given to someone else cannot quietly change afterwards.
Distinguish it from closing the books, which in some software means posting year-end entries that zero the income and expense accounts. No such entries exist here; the close is the routine and the lock is its last step.
What people get wrong
- Locking a period before reconciling it — reconciliation is meant to come first, so any discrepancy is caught while it's still fixable in place.
- Skipping the P&L review step and treating "reconciled" as the same thing as "ready to lock" — reconciliation only checks bank balances, not whether categorization looks reasonable overall.
- Letting month-end close slip to a quarterly or occasional habit — the value comes largely from catching small errors while they're still small.
Common questions
- What order should month-end close happen in?
- Reconcile every account first, categorize what's left, review the P&L, and only then lock the period through its last day — locking is the last step, not the first.
- Why reconcile before locking instead of after?
- Because reconciliation surfaces problems while they're still fixable in place. Locking first just means a later-discovered discrepancy has to be corrected with a reversing entry instead.
