Monthly Bookkeeping Checklist for Small Businesses

Meta Description:
Stay on top of your finances with this easy-to-follow monthly bookkeeping checklist designed for small business owners and entrepreneurs.

Introduction

As a small business owner, staying organized financially isn’t optional — it’s essential. Proper bookkeeping helps you understand your cash flow, prepare for taxes, and make informed business decisions.

But bookkeeping doesn’t have to feel overwhelming. This monthly bookkeeping checklist will help you keep your books accurate, updated, and ready for anything.

1. Record and Categorize All Income

At the start of each month, review every sale, invoice, and payment received. Make sure all income is properly categorized in your bookkeeping system.

• Record all client payments and sales.

• Match deposits to corresponding invoices.

• Track pending or overdue payments.

Pro Tip:
If you’re using software like QuickBooks or Wave, automate income tracking by linking your business account.

2. Reconcile Bank and Credit Card Accounts

Bank reconciliation ensures your recorded transactions match your actual bank statements.

• Compare each transaction line by line.

• Identify any missing or duplicate entries.

• Investigate unusual charges or withdrawals.

Why it matters: Accurate reconciliation prevents costly mistakes and keeps your financial data audit-ready.

3. Review and Categorize All Expenses

Go through your receipts, invoices, and digital transactions to make sure every expense is categorized correctly.

• Office supplies, fuel, and utilities.

• Business subscriptions (like accounting or CRM tools).

• Professional services (like bookkeeping or consulting).

Tip: Always separate business and personal expenses — it makes tax time much easier.

4. Check and Update Accounts Receivable

Don’t let unpaid invoices go unnoticed.

• Send reminders to late-paying clients.

• Mark paid invoices as completed.

• Track outstanding balances to maintain steady cash flow.

Automation Tip: Many accounting tools let you schedule automatic reminders for overdue invoices.

5. Update Accounts Payable

Stay on top of your bills and avoid late fees.

• Review all vendor invoices.

• Schedule payments ahead of due dates.

• Keep digital records of all payments made.

Consistent organization here builds strong relationships with suppliers and improves your financial reputation.

6. Review Financial Reports

At the end of each month, generate key reports to understand how your business is performing.

• Profit and Loss Statement (P&L): Shows your income and expenses.

• Balance Sheet: Displays your assets, liabilities, and equity.

• Cash Flow Statement: Helps track how money moves in and out.

Insight: Regular reporting helps you spot trends early — before they become problems.

7. Back Up Your Financial Data

Always back up your financial records at the end of each month. Cloud-based accounting tools make this automatic, but it’s smart to keep an additional local backup as well.

8. Schedule a Monthly Review with Your Bookkeeper
