Bookkeeping & Monthly Close

A Monthly Bookkeeping Checklist for Small Business Owners

A repeatable monthly close catches errors while information is fresh and turns accounting records into useful business decisions.

In this guide

Capture and Classify Activity

Confirm that every bank, card, payment processor, loan, payroll, and expense platform is represented. Review owner payments, transfers, loan proceeds, equipment, deposits, refunds, sales tax, and payroll carefully. Automated feeds help import data; they do not prove completeness or correct treatment.

Reconcile the Balance Sheet

Reconcile every bank and card account to its statement. Update loan balances and split principal, interest, and fees. Review receivables, payables, payroll liabilities, sales-tax payable, deposits, fixed assets, and equity for negative, old, or unexplained balances.

Review Operations

Compare the profit and loss statement to the prior month, prior year, and budget. Investigate significant changes in revenue, gross margin, payroll, marketing, occupancy, software, professional fees, and other major categories.

Review cash separately from profit. Customer timing, bill payments, equipment, debt principal, owner distributions, taxes, and inventory can change cash without matching current-period profit.

Prepare for Obligations

Update a short-term cash forecast and reserve funds for income, payroll, sales, and other taxes as appropriate. Review upcoming filing dates and verify that filed returns agree with the books.

Document and Close

Save statements, payroll reports, sales-tax returns, major invoices, loan documents, contracts, and notices. Resolve open questions, issue the reporting package, and apply a closing date to protect finalized periods. Document any later change.

Questions to Ask Before You Act

  • What decision are we trying to make, and by when?

  • Are the underlying books reconciled and current?

  • Which federal, state, local, industry, or contractual rules apply?

  • Who owns the next step, and what documentation should be retained?

Frequently asked questions

How often should bank accounts be reconciled?

At least monthly for most businesses; high-volume or cash-sensitive companies may benefit from more frequent review.

What reports should I review each month?

At minimum, profit and loss and balance sheet; add cash flow and aging reports when relevant.

Should I close the month in QuickBooks?

A closing date can help prevent accidental changes after review. Keep the password and change process controlled.

Is a bank feed enough for bookkeeping?

No. It imports activity but does not replace reconciliation, accounting judgment, or review for completeness.
