Month-End Close Checklist for Small Business

What is a month-end close checklist?

A month-end close checklist is the list of steps you run after a month ends to make the books accurate and final. You record all activity, categorize it, reconcile accounts, check invoices and bills, run reports and review them. The checklist makes the close the same every month.

A repeatable close gives you reports you can trust. It also keeps tax time calmer, because you fix small problems when they are new. For a plain definition, see the glossary entry on month-end close.

This guide builds on our earlier post, Month-End Bookkeeping Simplified in 7 Steps. Here you get the full checklist as a table, a timeline, and tips for each step.

What is the full month-end close checklist?

The checklist has ten tasks, run in a set order. Early tasks capture activity. Middle tasks check it. Late tasks report it. Work top to bottom, and do not run reports until reconciliation is done. Tick each box before you move on.

Copy the table into a spreadsheet and tick each box every month. If a task does not apply to you, delete it. Add tasks that are specific to your business, such as inventory counts.

How do I run each step?

Each step has a purpose and a common trap. Work through them in order. The notes below explain what to do and what to avoid, so the close finishes in one pass and does not need a second round.

1. Sync and record all activity. Make sure every bank, card and payment account feeds your software through the last day of the month. Missing feeds are the most common cause of surprise numbers.
2. Enter missing items. Add anything that did not sync, such as cash spending, paper checks and reimbursements. Chase the receipts for large items.
3. Categorize transactions. Assign every item to the right account in your chart of accounts. Review any automatic rules for errors. Clear the “uncategorized” account to zero.
4. Reconcile accounts. Compare your books to each statement, line by line. See bank reconciliation. Investigate every difference, even small ones.
5. Review customer invoices. Confirm that every sale has an invoice. Check accounts receivable for overdue items and plan follow-up.
6. Review bills and contractor payments. Enter every bill received. Check accounts payable for what you owe. Code contractor payments correctly so year-end 1099 work is easy.
7. Review liabilities. Match loan balances to lender statements and payroll totals to payroll reports. Check sales tax if it applies to you.
8. Run the reports. Produce the profit and loss statement and the balance sheet. Add reports for open invoices and unpaid bills.
9. Review and explain. Look for large changes. Ask why for each one. A jump in one expense may be a real event or a coding error.
10. Hold the review and lock. Meet to discuss results and next steps. Then lock the closed month so later edits are deliberate.

Why does reconciliation come before reports?

Reports only add up what is in the books. If an account is not reconciled, a report can look neat and still be wrong. A missed deposit or a duplicate charge flows straight into profit. Reconciling first means the report reflects the real bank balance.

Our post on bookkeeping blunders covers other mistakes that slip through when this step is skipped. For daily habits that make the close shorter, see these bookkeeping tips.

What does the timeline look like?

A good close spreads the work across the first week of the month. You do not need to finish on day one. A target date keeps the process moving. Peachtree aims to close out the prior month’s books and provide financial statements by the fifth business day of the new month.

The split of days is a sample plan. Every client’s account is different. During onboarding and kickoff, Peachtree sets a monthly cadence that fits each client’s needs. The fifth-business-day goal is the target in our standard process.

What should I look for in the reports?

Look for four things: income that matches your invoices, expenses that match your records, a balance sheet that ties to the bank, and changes you can explain. Reports are a tool for decisions. A number you cannot explain is a task, not a result.

Compare each month to the one before it and to the same month last year. Seasonal swings are normal. A change with no reason is not.

What if the books are behind?

Do not try to run a perfect close on months of backlog. Start with a catch-up project that brings the oldest months current, one month at a time. Then move to a monthly close. See catch-up bookkeeping for how that work is usually scoped.

How should the monthly review call go?

Keep the review call short and focused. Cover last month’s results, year-to-date numbers, and any budget or forecast changes. Then decide what to do. A review without decisions is a report you read and forget.

At the start of each month, your Peachtree bookkeeper meets with you to review the prior month’s performance, year-to-date results, and any budgets or forecasts that may need updating. Use a simple agenda:

1. Results: income, expenses and profit for the month
2. Year-to-date: how the year is tracking
3. Cash: balances, upcoming bills, overdue invoices
4. Questions: odd items and open coding questions
5. Decisions: price changes, spending cuts, hires, tax planning questions for your CPA

Tax questions belong with your CPA. Your bookkeeper keeps the data clean and ready. If you use cash or accrual reporting, see our guide on cash vs accrual accounting.

Can a bookkeeper run the close for me?

Yes. A bookkeeper can run the whole checklist so you only read the results. Peachtree bookkeepers categorize transactions, send invoices as needed, process contractor payments, issue 1099s when applicable, and reconcile accounts throughout the month. They work alongside your CPA.

The service covers transaction management, monthly financial reports, monthly reviews, account reconciliation, custom reports, CPA coordination, budget management and invoice management. Peachtree bookkeepers mainly work with QuickBooks Online. Read more about the role in the glossary entry on outsourced bookkeeping.

Bookkeeping packages start as little as $240 per month. Packages are based on your transaction volume and complexity. A free 30-minute consultation helps us scope your close.

What are the most common month-end close mistakes?

The most common mistakes are closing before reconciling, ignoring old open items, and letting the process drift. Each one is easy to fix with the checklist. The table shows what to watch for and how to respond, so the same problem does not repeat next month.

A good close also leaves a trail. Keep a copy of each month’s reconciled reports and a note on any open question. If your CPA asks about March in the following February, you can answer in minutes.

Finally, set one owner for the close. When two people each assume the other did a step, items fall through. Name the owner, set the date, and use the same checklist each month. Over a few months the close gets faster, and the numbers get easier to trust. If you use a bookkeeper, ask them to send the finished checklist along with the reports, so you can see each box ticked.
