The Complete Small Business Bookkeeping Checklist
Most bookkeeping guides give you a monthly checklist. That’s a start — but healthy books don’t happen monthly. They happen daily, weekly, and across the full year. This is the reference guide that covers every frequency.
Bookmark this page. It tells you what to do each day, each week, every month, every quarter, and once a year — so nothing falls through the cracks and tax time is never a crisis.
Just want the month-end steps? If you’re looking specifically for what to do at the close of each month, see the Month-End Bookkeeping Checklist — it covers the 8 steps to close your books each month in more detail.
Daily Bookkeeping Tasks
These take less than 10 minutes. Doing them daily prevents the pile-up that makes monthly closes painful.
1
Record Every Transaction
What to do: Log any money that came in or went out today. Sales, expenses, transfers, payments received — all of it goes into your accounting software before you close the day.
Why it matters: Transactions recorded same-day are accurate. Transactions recalled from memory a week later are guesses. Small daily habits prevent large monthly reconstruction sessions.
How long it takes: 2–5 minutes if you only had a few transactions.
2
Glance at Your Cash Balance
What to do: Check your bank account balance once a day. Know what you have available right now, not what your P&L says you made.
Why it matters: Profit and cash are different. You can be profitable on paper and still not have enough cash to pay this week’s bills. A daily cash check keeps you grounded in reality.
How long it takes: 1 minute.
Weekly Bookkeeping Tasks
Pick a consistent day — Friday afternoon or Monday morning both work well. These tasks prevent small issues from compounding into the next month.
3
Send and Review Outstanding Invoices
What to do: Send any invoices from this week’s work. Then pull up your invoice list and check which invoices are still unpaid. Flag anything over 14 days old.
Why it matters: The sooner you invoice, the sooner you get paid. And the sooner you follow up on overdue invoices, the higher your collection rate. Invoices forgotten for a month become much harder to collect.
How long it takes: 10–15 minutes.
4
Categorize Any Uncategorized Expenses
What to do: Open your accounting software and look for any transactions without a category. Assign each one — office supplies, marketing, software, travel, etc. Attach receipts while you still remember what they were for.
Why it matters: A week of transactions is manageable. A month of uncategorized transactions takes hours to sort through. Doing it weekly keeps your expense reports accurate all month long.
How long it takes: 5–20 minutes depending on transaction volume.
5
Review Bills Due This Week
What to do: Check what vendor bills or payments are due in the next 7 days. Confirm you have enough cash to cover them. Schedule payments for anything due in the coming week.
Why it matters: Late payments damage vendor relationships and sometimes incur fees. Knowing what’s due this week — not this month — gives you enough time to act if cash is tight.
How long it takes: 5–10 minutes.
Monthly Bookkeeping Tasks
These are your month-end close steps. Do them within the first week of the following month, once your bank statement closes. Budget 60–90 minutes.
For a full step-by-step walkthrough of each task below, see the Month-End Bookkeeping Checklist.
6
Reconcile Bank and Credit Card Accounts
Match every transaction in your accounting software to your bank and credit card statements. Your software balance should equal your statement balance to the cent. Any difference means a missing transaction, duplicate, or error that needs to be found and fixed.
7
Clear All Uncategorized Transactions
Every transaction from the month must have a category before you close the month. Uncategorized transactions break your expense reports and make your P&L unreliable.
8
Review Accounts Receivable Aging
Run an A/R aging report. Send follow-up messages for anything over 30 days overdue. Consider writing off anything 90+ days old that you’ve been unable to collect.
9
Review Accounts Payable
Check what you owe and when it’s due. Make sure nothing is overdue. Plan next month’s cash outflows so you’re not caught short.
10
Review Expense Trends
Run an expense report by category. Look for any category that’s significantly higher or lower than last month. Investigate spikes — they’re often billing errors, duplicates, or miscategorized transactions.
11
Generate and Review Profit & Loss Statement
Pull your P&L for the month and year-to-date. Compare to last month and to the same month last year. Track trends — are you becoming more or less profitable? Are expenses growing faster than revenue?
12
Review Balance Sheet
Generate a balance sheet as of month-end. Confirm it balances (assets = liabilities + equity). Check that cash matches your reconciled bank balance. Verify equity is moving in the right direction.
Quarterly Bookkeeping Tasks
Once every three months — at the end of March, June, September, and December. These tasks look at the bigger picture your monthly reviews can’t see.
13
Review Estimated Tax Obligations
What to do: If you make estimated tax payments (most self-employed owners and small businesses should), calculate what you owe for the quarter and pay it by the due date. Your bookkeeper or accountant can calculate this from your quarterly P&L.
Why it matters: Missing estimated tax payments triggers penalties and interest. Paying them quarterly keeps you current and prevents a large unexpected bill at year-end.
14
Compare Actuals vs. Budget
What to do: If you have an annual budget, compare your actual revenue and expenses to what you planned for the year so far. Where are you ahead? Where are you behind?
Why it matters: Monthly reviews show you what happened. A quarterly budget comparison tells you if you’re on track for the year. If you’re 30% behind on revenue in Q1, you know now — not in December.
15
Review Three-Month P&L Trends
What to do: Pull a side-by-side P&L for the last three months. Look at revenue, cost of goods, and major expense categories month over month. Are there clear trends?
Why it matters: One bad month could be seasonal or a one-off. Three months of a downward trend is a signal that something needs to change. You won’t see this pattern in a single month’s report.
16
Review Contractor Payments for 1099 Tracking
What to do: Run a report of all payments made to contractors and freelancers this quarter. Make sure you have their tax information on file for anyone you’ve paid more than $600 so far this year.
Why it matters: If you don’t collect contractor tax information before paying them, you’ll scramble to get it at year-end. Some contractors become unreachable. Collecting quarterly keeps you compliant.
Annual Bookkeeping Tasks
These happen once a year — typically in December (to prepare) and January through April (to execute). If you’ve done the daily, weekly, monthly, and quarterly tasks consistently, these are fast.
17
Close the Year in Your Accounting Software
What to do: Once December is fully reconciled and your accountant has reviewed everything, close the fiscal year in your software. This locks the period so no one accidentally posts transactions to the prior year.
Why it matters: An open prior year means a careless entry can corrupt your year-end figures. Closing it protects the numbers your accountant will use for tax prep.
18
Issue 1099s to Contractors
What to do: By January 31st, send the appropriate contractor reporting forms to any freelancer you paid $600 or more during the year. File copies with your tax authority. Outside the US, follow your country’s equivalent contractor reporting rules.
Why it matters: This is a legal requirement. Late or missing contractor reports carry penalties. If you’ve been collecting tax information quarterly (task #16 above), this step is a 30-minute admin task instead of a headache.
19
Prepare a Year-End Financial Package for Your Accountant
What to do: Pull together your final P&L for the year, year-end balance sheet, list of fixed asset purchases and disposals, loan statements, and any adjusting journal entries your accountant needs. Share this as a clean package — not a raw export.
Why it matters: Accountants charge by the hour. A clean package means faster, cheaper tax prep — and fewer questions back to you.
20
Review the Chart of Accounts and Clean Up Unused Categories
What to do: Go through your chart of accounts and archive or delete any categories you haven’t used in the past year. Make sure your category names are still accurate. Add any new categories you’ll need next year based on how your business has changed.
Why it matters: A bloated chart of accounts makes categorization slower and reports harder to read. Cleaning it up once a year keeps your books organized and your reports useful.
Use This as Your Year-Round Reference
Bookmark this page or copy the headings into a task manager. The goal is the same regardless of format: run through the right items at the right frequency, and your books stay clean all year.
