The bookkeeping checklist every SMB should be following

Atul Gawande, author of “The Checklist Manifesto,” once said, “The volume and complexity of what we know has exceeded our ability to deliver its benefits correctly, safely, or reliably.” Or, in plainer terms, humans know so much, and our expectations are so high, that we often reach a point of being unable to deliver on the knowledge we possess to its fullest extent.

Take bookkeeping, for instance. For those of us who have gone through school and understand basic budgeting and business principles, keeping a budget is generally straightforward. However, adding on HR, new business, supply chain, and business-building initiatives, even the most knowledgeable people will have things slip through the cracks, because of “the volume and complexity of what we know.”

Bookkeeping is easy to ignore and hard to fix

Unfortunately, with bookkeeping, it is easy to ignore and incredibly difficult to fix. A lot of SMBs slip into deferring their bookkeeping responsibilities until they are left with an unreconciled financial mess.

In the early days of a business, transactions are often simple enough math to all be done without paper, computers, or calculators. But, as your business grows, so does the complexity of your finances, as: 

• Invoices pile up. 
• Expenses go uncategorized. 
• Bank statements don’t match what’s in your system. 
• Money gets spent in your business that you are no longer singularly authorizing.

Before you know it, tax season arrives and you’re stuck scrambling through receipts, spreadsheets, and late-night fixes. That’s why consistent, proactive bookkeeping isn’t just a nice-to-have—it’s a must-have. And the best way to stay on track is with a trusted, thorough, and repeatable checklist.

Why a checklist is essential

A bookkeeping checklist helps the busy modern-day entrepreneur stay organized by breaking financial maintenance into manageable, digestible bites. Instead of wondering what needs to happen each month, quarter, or year, you’ll know exactly what and when to review, update, and reconcile. 

With a clear process in place, you can catch minor errors before they snowball into bigger issues, maintain clean books for tax filing, and never worry about hitting your tax deadlines again. If you’re handling the books yourself, great. If you’re working with a finance partner, also great. A checklist brings structure and accountability to everyone touching finances in the back office.

This article breaks down a bookkeeping checklist that every business should complete monthly, quarterly, and annually. Remember, it’s not about doing everything yourself—it’s about making sure everything gets done accurately and compliantly. With the right system, bookkeeping becomes less of a burden and more of a growth tool. 

How to use this checklist for bookkeeping

This checklist is built for small business owners and operations leads who are managing finances on top of everything else. You don’t need to be an accountant but you do need a process.

In The Checklist Manifesto, Atul Gawande writes that “checklists can’t fly planes, but they can provide reminders of the most pivotal and important steps—the ones that even the most highly skilled professionals using them could miss.”

That’s the point here. This checklist breaks your bookkeeping into three repeatable cadences: monthly, quarterly, and annually. Spread tasks across the year, and suddenly your books become easier to maintain and easier to delegate.

If your team shares responsibilities or uses accounting software, this list helps you stay aligned. It doesn’t replace your tools, bug instead it reinforces them. And because it’s platform-agnostic, you can manage it in a spreadsheet, project tracker, or task management app. Whatever fits your workflow.

Bookkeeping at a glance

This quick summary shows what needs to happen and when. Start here. Then tackle each section in detail below.

• Monthly: Reconcile accounts, categorize expenses, upload receipts, review reports
• Quarterly: Review your budget, submit estimated taxes, adjust financial entries
• Annually: Close your books, send 1099s/W-2s, prep for taxes with your advisor

Monthly bookkeeping checklist

Here are the recurring tasks you should complete monthly to keep your books clean.

Step 1. Reconcile bank and credit card accounts

Start by matching your books to your bank and credit card statements. Every transaction should line up with your statements so you can spot errors, missing entries, or unauthorized charges early. Reconciliation is the foundation of accurate financials—if this step isn’t done, everything that follows could be off.

Step 2. Categorize and record all transactions

Once everything’s reconciled, make sure each transaction is labeled correctly. Revenue, payroll, marketing, travel—each category gives you clarity into how money moves through your business. Mislabeling or skipping this step is one of the most common bookkeeping mistakes and can distort your financial reports.

Step 3. Upload and organize receipts

Digital records matter. Upload all receipts and match them to the correct transactions. This step keeps you audit-ready and makes tax season much easier. Many tools let you snap photos or forward receipts by email, but you still need to ensure they’re linked correctly.

Step 4. Review income and expenses for accuracy

Scan your income and expense lines for odd spikes, duplicates, or missing entries. This monthly review helps catch minor issues before they become big ones and gives you an up-to-date picture of your business's performance.

Step 5. Generate monthly P&L and cash flow reports

Wrap up each month with two essential reports: your Profit & Loss (P&L) and your cash flow statement. These give you insight into profitability and liquidity, which are key to making informed decisions. Don’t just generate them—review them.

Quarterly bookkeeping checklist

Every quarter is a chance to step back, look at the bigger picture, and ensure your financial systems keep pace with your business and position you for the future. These quarterly tasks go beyond basic maintenance—they help you stay compliant, catch long-term issues early, and prepare for strategic decisions.

Step 1. Review and adjust the budget/forecast

Compare your actual performance against your budget or forecast. Are you on track with revenue goals? Are expenses creeping up in certain categories? Use this review to recalibrate your plans and make informed decisions for the next quarter.

Step 2. Double-check estimated tax payments

Make sure you’ve calculated and submitted estimated tax payments accurately. Missing or underpaying can lead to penalties down the road. This is crucially important for businesses without tax withholding, like LLCs and S-Corps.

Step 3. Reconcile loans, payroll, and deferred expenses

Go deeper than your monthly reconciliations. Review outstanding loans, make sure payroll liabilities are correctly accounted for, and adjust any deferred revenue or expenses. These entries can get overlooked if you’re only focused on cash flow.

Step 4. Review and update the chart of accounts (if needed)

As your business evolves, your chart of accounts may need to as well. Remove unused accounts, consolidate overlapping categories, and ensure your financial structure reflects your business's current state. A clean chart makes reporting easier and more accurate.

These quarterly tasks strengthen your financial foundation so you’re ready for taxes, investor updates, or big decisions ahead. Consider blocking time at the start of each new quarter to complete them, or let Pilot handle it for you.

Annual bookkeeping checklist

The end of the year is more than just wrapping up—it’s a financial reset and review. These annual bookkeeping tasks will prepare you for filing your taxes, and pave a clear path forward to the next fiscal year.

Step 1. Close out books and prepare year-end financial statements

Start by making sure all transactions are recorded, reconciled, and categorized. Then generate final financial statements: the Profit & Loss statement, balance sheet, and cash flow report. These are essential for tax filing, investor reporting, and strategic planning.

Step 2. Organize and archive receipts and records

Ensure all receipts, invoices, and financial documents are properly stored and easily accessible. Keep digital backups and organize them by category or month. This is critical for audits and saves significant time and stress if you need to reference something later.

Step 3. Send 1099s and W-2s (if applicable)

If you paid contractors $600 or more during the year, you must send them 1099s by January 31 of the following year. The same applies to W-2s for employees. Make sure your payroll and vendor records are accurate to avoid delays or penalties.

Step 4. Schedule a tax review or consult

Before filing, meet with your accountant or tax advisor to review your financials, returns, discuss deductions, and plan for any last-minute adjustments. It’s also a good time to evaluate cash reserves, review business structure, and revisit your financial goals.
