How to Conduct a Monthly Financial Audit

Why Conducting a Monthly Financial Audit Matters

A monthly financial audit isn’t just for big corporations—it’s how smart small business owners keep control of their cash flow, catch errors early, and stay compliant. By reviewing your books each month, you’ll spot red flags before they snowball into IRS headaches or cash shortfalls.

In short: it’s cheaper to prevent a problem than to fix one.

Step-by-Step Instructions

Step 1: Reconcile All Accounts

• Match every bank, credit card, and loan account to your bookkeeping records.

• Verify all deposits and withdrawals appear correctly.

• Look for duplicate transactions or missing entries.

Tip: Do this by the 5th of each month, while transactions are fresh in your memory.

Step 2: Review Income and Expenses

• Confirm all invoices have been issued and received.

• Check expense categories for accuracy—miscategorized expenses can distort profitability.

• Compare actual results to your budget or prior month to identify anomalies.
  

Step 3: Audit Your Payroll and Contractor Payments

• Ensure tax withholdings, benefits, and hours are correct.

• Cross-check contractor payments against signed agreements and Form 1099 tracking.
  

Step 4: Verify Balance Sheet Accuracy

• Review outstanding loans, assets, and owner draws.

• Confirm all asset purchases and depreciation schedules are updated.
  

Step 5: Prepare and Store Documentation

• Keep digital copies of bank statements, receipts, and reports in a structured folder (e.g., “Financials > 2025 > October Audit”).

• Maintain an internal audit trail so anyone can follow your process later.

Pro Tips from Experience

• Set a recurring date: Block time monthly (ideally the first Monday) for your internal audit.

• Don’t multitask: Treat it like client work—phone off, email closed.

• Use comparative reports: Reviewing month-over-month trends reveals issues faster than scanning raw numbers.

• Keep a notes log: Record any irregularities or follow-ups to discuss with your accountant.

• Automate what you can: Bank feeds, rules, and AI-driven categorization reduce manual errors.

Common Pitfalls Ignoring small variances that could signal fraud or accounting errors Failing to reconcile all accounts (especially loans or savings) Waiting until year-end to clean up books—creating chaos at tax time Mixing personal and business expenses Skipping documentation, making audits and compliance checks harder later
