Monthly Bookkeeping Checklist

Here’s what every small business should be doing each month to stay on top of their books:

Task	Why It Matters
Reconcile bank and credit card accounts	Catch errors, fraud, or duplicate charges early
Categorize income and expenses	Keeps your financial reports accurate and tax-ready
Review outstanding invoices (Accounts Receivable)	Stay on top of unpaid customer invoices and follow up
Track unpaid bills (Accounts Payable)	Avoid late fees or interest charges
Run a Profit & Loss (P&L) report	Understand your income vs. expenses month-to-month
Check your cash flow	Plan for upcoming expenses and make smarter spending decisions
Back up your financial data	Protect your business in case of software crashes or data loss

"Founders who wait until the end of the year to clean their books always regret it. Monthly reconciliation saves money—and your sanity." — Accountant on Sam’s List

Year-End Bookkeeping Checklist

When the calendar year wraps up, here’s what to check off:

Task	Why It Matters
Reconcile all bank and credit accounts for the year	Ensures no transaction is missed before filing taxes
Review and clean up your Chart of Accounts	Makes reports cleaner and more useful for strategy or audits
Run year-end financial reports (P&L, Balance Sheet, Cash Flow)	Gives a full snapshot of your business performance
Review fixed assets and depreciation	Helps with accurate tax reporting and deductions
Collect W-9s and issue 1099s if needed	Required for contractors/vendors who earned $600+
Verify payroll tax filings and W-2s	Prevents penalties and keeps your team compliant
Meet with your accountant or tax pro	Prepares you for filing and planning for next year

Bonus Tips for Staying Organized

• Use accounting software like QuickBooks or Xero to automate recurring tasks
• Schedule a recurring “Finance Friday” once a month to tackle bookkeeping tasks
• Keep digital copies of all receipts and documents using tools like Google Drive or Hubdoc
• Hire a pro when it gets too complex — messy books cost more to clean up later

One Sam’s List client shared they spent 10+ hours reconciling last year’s books—and still missed over $3,000 in deductions. “I should’ve brought in a pro months earlier.”

FAQs

How often should a small business do bookkeeping?

Ideally, every week or month. Waiting until year-end leads to mistakes and missed opportunities.

What bookkeeping tasks can I outsource?

Everything from categorizing expenses to generating reports, issuing 1099s, and tax prep.

Is bookkeeping software enough?

Software helps, but only if you know what to do with it. Hiring a pro ensures accuracy and strategy.

Do I need a bookkeeper or an accountant?

Start with a bookkeeper to keep things organized. Bring in an accountant for tax strategy, compliance, or growth planning.
