Check your books at the end of the month
Use a practical review order before sharing reports or deciding the month is complete.
A month-end review checks whether the month’s records are complete and consistent. This checklist does not automatically close or lock an accounting period.
Work through the records first
Section titled “Work through the records first”- Confirm the company and month you are reviewing.
- Review missing bank activity, unreviewed rows, and duplicate imports. Match existing records before categorizing new activity.
- Reconcile bank and card accounts to their statements.
- Review unpaid invoices and bills, partial payments, and credits. Investigate amounts that should have been settled.
- Review customer deposits and other unapplied amounts separately from ordinary unpaid invoices.
- Check inventory quantities and source transactions if you track stock.
- Review sales tax for the period where applicable.
For example, a $500 customer receipt in the bank does not prove a $500 invoice has been settled correctly if the receipt is still unapplied or was categorized as another sale.
Review the reports together
Section titled “Review the reports together”Run Profit and Loss, Balance Sheet, and Trial Balance. Confirm the dates and accounting method before comparing them with prior reports. Review A/R Aging Summary and A/P Aging Summary for outstanding balances.
Follow unusual balances back to their source records. Negative balances, large changes, and old credits are review prompts, not automatic proof of an error.
Correct the cause, then rerun
Section titled “Correct the cause, then rerun”Fix a duplicate, missing payment link, incorrect date, or misclassified source transaction through its allowed workflow. Do not post an arbitrary journal simply to make a report agree.
Accruals, depreciation, prepaid expenses, and revenue recognition may require accountant-reviewed adjustments. This checklist does not imply those calculations happen automatically.
Keep a review record
Section titled “Keep a review record”Save the reports with their dates and basis, reconciliation evidence, and a short list of unresolved items. Share these with your accountant. If the company uses period locks, agree who may close or reopen periods before changing prior-month activity.
Worked month-end check
Section titled “Worked month-end check”This simplified example uses accrual accounting, no tax, fees, inventory, or opening receivables/payables, and illustrative amounts:
| Event | What to record | Result to check |
|---|---|---|
| Earn $1,000 and invoice the customer | Invoice | Revenue $1,000; A/R $1,000 |
| Receive $700 against it | Customer payment | Cash +$700; A/R $300 |
| Receive a $400 bill for this month’s services | Vendor bill | Expense $400; A/P $400 |
| Pay $250 against the bill | Bill payment | Cash −$250; A/P $150 |
Expected results for this example are $600 profit, $450 net cash increase, $300 receivable, and $150 payable. Match bank activity to the two existing payments, reconcile to the statement, and check the reports using the same dates. Adding bank income and expenses again would count the money twice.
Once the review is complete, close the period. These amounts illustrate how the records connect; they are not a transaction test performed in your company.
Use the Audit Log to investigate who changed a record and compare the change with the current ledger.
