Turn month-end from a scramble into a repeatable routine.

1. Gather the source records
Collect statements for bank accounts, cards, loans, and payment processors. Add sales reports, vendor invoices, payroll summaries, and explanations for unusual transactions. Keep a list of missing items so the close does not silently depend on incomplete information.
2. Reconcile before interpreting
Match statement balances to the books and investigate differences. A bank feed is a data source, not a completed reconciliation. Check transfers between accounts so they are not mistaken for income or expenses. Review old uncleared transactions instead of carrying them forward indefinitely.
3. Review the balance sheet
Look beyond the income statement. Ask whether receivables are collectible, vendor balances are complete, loan balances agree with statements, and owner activity is recorded consistently. An unexplained balance is a question to resolve, not simply a number to accept.
4. Write down what changed
Compare the period with the budget or a meaningful prior period. Identify unusual sales, cost changes, one-time purchases, and timing differences. A short commentary can be more useful than an extra page of ratios. Assign an owner and a resolution date to open questions.
5. Preserve the completed period
Keep the agreed reports and supporting schedules together, record any unresolved limitations, and define how later adjustments will be approved. The checklist should be small enough to use consistently and detailed enough to make responsibilities clear.
