Month-End Close Checklist for a Small Business
A month-end close is the set of steps that makes one month's books final: record every transaction, reconcile every bank, card and loan account, post adjusting entries, review the numbers, then produce the profit and loss, balance sheet and cash flow statement and lock the period. SF Business Solutions closes client books between the 5th and 15th of the following month, depending on when documents arrive.

The checklist, in order
Work through the steps in this order each month. Skipping ahead, for example reviewing the P&L before the accounts are reconciled, means reviewing numbers that can still change.
| Step | What to do | Who | When |
|---|---|---|---|
| 1. Collect documents | Bank, card and loan statements, receipts, sales and bill records, payroll reports | Owner or office manager | First days of the new month |
| 2. Record transactions | Categorize every bank and card transaction; leave nothing uncategorized | Bookkeeper | Through the month |
| 3. Reconcile cash accounts | Match every bank, credit card and loan balance to its statement | Bookkeeper | As statements arrive |
| 4. Accounts receivable | Match customer payments to invoices and review the aging report | Bookkeeper | Close week |
| 5. Accounts payable | Enter unpaid bills and confirm what was paid | Bookkeeper | Close week |
| 6. Payroll | Record gross wages, employer taxes and benefits from the payroll report | Bookkeeper | Close week |
| 7. Adjusting entries | Accruals, prepaid expenses, depreciation and loan interest | Bookkeeper or accountant | Close week |
| 8. Inventory | Record counts or adjustments and update cost of goods sold | Bookkeeper with the owner | If you hold stock |
| 9. Review | Compare with last month, last year and budget; investigate anything unusual | Accountant or reviewer | Before reports go out |
| 10. Report and lock | Produce the three statements and set a closing or lock date | Bookkeeper | End of the close |
Reconciliations: the step you can't skip
A reconciliation proves that the balance in your books matches the balance the bank, card company or lender reports on the statement date. Every difference is either a timing item, such as a check that hasn't cleared, or a mistake to fix: a missing transaction, a duplicate, or a payment coded to the wrong account.
Reconcile every cash account, every credit card and every loan, even the ones that barely move. An unreconciled account is where errors hide, and it is the first thing a lender, auditor or tax preparer asks about.
Adjusting entries most small businesses need
Adjusting entries move income and costs into the month they belong to. Cash-basis businesses need fewer of them, but most still record some.
- Accrued expenses: bills for work done this month that arrive next month
- Prepaid expenses: annual insurance or software paid up front and spread across the months it covers
- Depreciation on equipment and vehicles
- Loan payments split between principal and interest
- Payroll accrued for days worked but paid next month
- Deferred revenue for customers who paid in advance
Common mistakes
These are the problems that most often turn a clean close into a cleanup project later:
- Leaving an "uncategorized" or "ask my accountant" balance at month end
- Reconciling to the bank app's current balance instead of the statement balance
- Recording owner draws or personal spending as business expenses
- Editing a closed month without telling anyone, which changes reports already sent
- Skipping the review, so an unusual number reaches your lender or your tax return unchecked
How SF Business Solutions closes the month
We follow this checklist for every client in QuickBooks Online or Xero, and the books are closed between the 5th and 15th of the following month, depending on when your documents arrive. You get a profit and loss statement, a balance sheet and a cash flow statement, and at year end we prepare and file your tax return from the same books. Our team includes one licensed CPA, and monthly bookkeeping starts at $250 a month.
How long should a month-end close take for a small business?
It depends on transaction volume and how quickly statements and receipts arrive. Our clients' books are closed between the 5th and 15th of the following month, depending on when documents arrive.
What is the most important step in the month-end close?
Reconciling every bank, credit card and loan account to its statement. Without it, reports can look right and still be wrong.
Should I lock the period after closing?
Yes. QuickBooks Online and Xero both let you set a closing or lock date so nobody changes a finished month by accident.
What reports come out of the close?
A profit and loss statement, a balance sheet and a cash flow statement, plus receivable and payable aging reports if you invoice or pay on terms.
Do I need accrual accounting to do a month-end close?
No. A cash-basis business still records, reconciles and reviews every month; accrual accounting adds entries for income earned and costs incurred but not yet paid.
