A monthly bookkeeping checklist for small-business owners

Choose a workable routine

Set aside a recurring time to organize business records. A process that you can sustain is more useful than a complicated system that is abandoned after a week. Decide who collects documents, who enters transactions and who reviews questions. The IRS allows recordkeeping systems suited to the business that clearly show income and expenses.

Collect supporting records

Keep the records behind the numbers, not just a balance displayed in an app. Relevant documents may include invoices, sales records, receipts and bank statements. The IRS provides examples of supporting documents for business income, purchases, expenses and assets. Ask your accountant which records are needed for your activities and how they should be retained.

Resolve open questions

Create a short list of unidentified payments, transfers and missing receipts rather than guessing. Add a plain-language note explaining what you know. If money moved between the owner and the business, flag it for review. This is an organizational step, not a recommendation about how a transaction should be classified for tax purposes.

Review reports together

Ask your bookkeeper what has been reconciled and what is still incomplete. Discuss unexpected changes in sales, expenses or account balances. Save a dated copy of the reports used in the conversation so that later changes can be understood. Avoid treating a draft report as final simply because it came from accounting software.

Prepare the tax handoff

Before year-end, ask the tax preparer for a document list and timing requirements. Agree on how bookkeeping adjustments will be communicated back to the person maintaining your records. Good coordination can make the work easier to follow; it does not replace professional review of the records or the return.
