What a monthly close actually includes, and why it matters

If your bookkeeper sends you a profit and loss each month, you might assume the books are "done." But a set of reports is only as reliable as the work behind it. That work is the monthly close: a fixed set of steps that confirms every number before anyone relies on it.

Here is what a proper close includes.

1. Every transaction is recorded. Bank and card feeds are complete for the month, and bills, invoices and other activity outside the bank are entered too.
2. Transactions are categorized correctly. Each one is coded to the right income or expense account. Miscoded transactions are the most common reason a P&L looks wrong.
3. Every account is reconciled. Each bank, credit card and loan balance in the books is matched to its statement. If they differ, the difference is found and fixed, not plugged.
4. Payables and receivables are reviewed. The aging reports show who owes you and whom you owe. Old items are investigated: an invoice that is "unpaid" for 200 days may really have been paid and recorded wrong.
5. The balance sheet is reviewed. Accounts like loans, payroll liabilities, sales tax payable and owner's equity are checked for balances that don't make sense.
6. A second person reviews the results. A senior accountant looks for unusual swings, missing expenses and anything that needs your input.
7. Reports are delivered. You receive the balance sheet, profit and loss and cash flow statement, with notes on anything that changed.

Why it matters

Skipping steps creates problems that compound. An unreconciled account can hide a duplicate payment, a missed deposit or fraud for months. A P&L built on uncategorized transactions leads to bad decisions about pricing, hiring or spending. And at year end, your CPA has to untangle it all, usually at a higher rate than a bookkeeper.

A consistent monthly close means your numbers are ready when you need them: for a loan application, an investor conversation or simply knowing whether last month was profitable.
