Month-end checklists come in two sizes. There's the 140-row spreadsheet someone downloaded from a big-company template, with columns for "preparer," "reviewer" and "SOX reference." And there's the sticky note that says "do the books."
Neither one gets used. The spreadsheet is too much for a 12-person company, and the sticky note is too little for anyone.
This month end close checklist for small business sits in the middle. It's built for owners and small teams who want reliable monthly numbers without pretending to be a public company. Print it, copy it into your project tool, or tape it to the monitor. It works best if it lives somewhere you'll see it on the 3rd of the month.
Before you start: set the cutoff
The close is about one month, so decide what belongs in it. Anything dated in the month should be in the month, even if the bill arrives on the 4th. That's the idea behind accrual accounting (recording income and expenses when they're earned or incurred, not when cash moves). If you run your books on a cash basis, you'll skip some steps below, and your CPA can confirm which basis fits your business.
Gather these first:
- Bank, credit card and loan statements for the month
- Payroll registers for every pay date in the month
- Payment processor reports (Stripe, Square, Shopify payouts)
- Any bills or invoices dated in the month that haven't been entered
The month end close checklist
Cash
- Categorize every bank and card transaction for the month.
- Match deposits to customer payments, and payments to bills, instead of creating new income or expenses.
- Reconcile every bank and credit card account to its statement. The difference should be zero.
Receivables and revenue
- Confirm every invoice for work done in the month was sent.
- Apply customer payments to the right invoices.
- Review the A/R aging for anything old or odd.
Payables and expenses
- Enter all bills dated in the month.
- Review the A/P aging for duplicates and bills paid outside the system.
Payroll
- Record payroll from the register: wages, employer taxes and liabilities.
- Confirm payroll liability balances match what's owed after the month's tax deposits.
Balance sheet and adjustments
- Reconcile loans and lines of credit to lender statements, splitting principal and interest.
- Post recurring entries: depreciation, prepaid expense amortization, accruals.
- Clear holding accounts like Uncategorized, Ask My Accountant and Undeposited Funds.
Review and report
- Have someone other than the preparer review the P&L and balance sheet.
- Compare to last month and to budget. Explain any big swings.
- Lock the period.
- Send reports with a short written summary.
Seventeen steps. Some take two minutes. Number 3 takes longer the first time, and gets faster every month after.
A worked example: a nine-person agency's close
Say you run a nine-person creative agency with two checking accounts, one savings account, two credit cards and a line of credit. Here's what a close might find in a normal month:
- Step 3: one card is off by $412. The cause is a vendor refund that came through as a duplicate. Fixed.
- Step 6: a $7,500 invoice is 75 days old. Turns out the client paid, and the deposit was booked as income. The deposit gets applied to the invoice, removing $7,500 of doubled revenue.
- Step 12: annual insurance of $4,800 was paid in January and expensed all at once. A prepaid entry spreads it at $400 a month.
- Step 15: gross margin dropped from 46% to 39%. The review finds $6,000 of freelancer costs for next month's project booked early. They get moved.
Without the close, that month's P&L would have overstated revenue by $7,500 and misstated costs in both directions. With it, the owner gets a number she can plan around. And if you're wondering why reconciling the balance sheet matters as much as the P&L, read balance sheet reconciliation: the report nobody reads until it's too late.
Monthly close best practices that make the checklist stick
- Pick a close date and put it on the calendar, like the 10th business day.
- Give every step an owner. "We" doesn't reconcile accounts.
- Keep a running list of questions during the month instead of saving them all for the close.
- Use the same report package every month so changes stand out.
- Review last month's open items before starting this month.

What the close is really for
A checklist gets the steps done. The point of doing them is a set of numbers that tell you something: how much you made, where cash went, what you owe and what's changing. We wrote more about that in what the month-end close is actually supposed to tell you.
When the close starts producing questions about margins, cash and forecasts, that's the point where controller oversight helps. Our controller services cover the review, the close calendar and the reporting package.
Questions owners ask
What should be included in a month end close checklist?
Reconciling bank and credit card accounts, updating receivables and payables, recording payroll, reconciling loans and other balance sheet accounts, posting adjustments, reviewing the results, locking the period and sending reports.
Who should do the month-end close in a small business?
Usually a bookkeeper prepares it and someone else reviews it, such as a controller, an accounting manager or the owner. Having a second person review catches errors the preparer is likely to miss.
Do small businesses on cash basis need a month-end close?
Yes. Cash-basis books still need reconciled accounts, recorded payroll, cleared holding accounts and a review. You'll just skip accrual steps like entering unpaid bills or prepaid amortization.
