What does closing an accounting period do?
It marks a date range as closed so ordinary transactions cannot continue changing a period that has already been reviewed.

Month-end close is the point where “we will fix it later” becomes a reporting problem.
Closing a period means deciding that the accounting records for a defined date range are complete enough to rely on. The work is less about pressing a close button and more about resolving the loose ends before the period is locked.
A useful close process checks whether transactions belong in the right period, journals are posted and balanced, customer and supplier balances make sense, bank activity has been reviewed and material currency issues are understood.
The exact checklist depends on the business, but the principle is stable: resolve known exceptions before making the period harder to change.
01
Start with the period boundary
Confirm the start and end dates being closed and decide how late-arriving transactions will be handled. A transaction dated in the closed month can change reports even if someone enters it weeks later.
Clear cutoff rules reduce arguments about whether a late invoice, bill or journal belongs in the old period or the new one.
02
Review journals before locking the period
Draft or unposted journals can signal incomplete accounting work. Posted journals should balance and have enough description to explain why they exist.
Fixing an unexplained journal is easier before the period closes than after managers have already used the reports.
03
Check customer invoices and receivables
Review overdue invoices, credits, unapplied or partial payments and unusual old balances. The objective is not to collect every invoice before close, but to make sure the receivable position reflects the records the business actually has.
Large or unusual adjustments deserve explanation before the reporting period is treated as finished.
04
Review supplier bills and payables
Check bills awaiting review, overdue supplier balances and purchasing mismatches that could affect the liability position. Receiving activity may also create obligations before the final supplier bill arrives.
A clean close distinguishes genuine timing differences from records that are simply missing.
05
Review bank reconciliation status
Imported statement activity should be matched or explained enough that unexplained differences do not hide inside the cash balance. Unmatched lines and exceptions deserve attention before the period is considered ready.
The goal is not a perfect-looking percentage; it is confidence that significant bank activity has an accounting explanation.
06
Resolve material currency exceptions
Foreign-currency invoices, supplier bills and payments can create exchange differences. Missing or inconsistent rates can also distort base-currency reporting.
Review significant exceptions before close rather than discovering them later in a balance that no longer ties back to the source transaction.
07
Close only after the readiness questions are answered
Once the team is satisfied, closing the period prevents ordinary posting into dates that have already been reported. That protects the reports from casual late changes.
Reopening or correcting a closed period should therefore be deliberate and traceable rather than the default way to finish forgotten work.
Month-end close checklist

- Draft and unposted journals reviewed.
- Posted journals balanced.
- Receivables and credits reviewed.
- Supplier bills and overdue payables reviewed.
- Bank reconciliation exceptions reviewed.
- Material foreign-currency issues reviewed.
- Reports checked before the period is locked.
- Any later correction follows a deliberate process.
