How to do your own bookkeeping as a small business owner

This article was paid for by Intuit QuickBooks.

More than two-thirds of U.S. small business owners take a DIY approach to bookkeeping, according to QuickBooks' Business Owner Report survey conducted in December 2025.

The report found that 13% of respondents rely on spreadsheets or pen and paper. Another 28% use accounting and tax software to track their finances, and 26% manage their day-to-day books but hire a professional at tax time. 

Only 21% work with a dedicated accountant or bookkeeper year-round.

Accounting software automates much of the work, reduces mistakes, and frees up your time to focus on growing your business.

Bookkeeping is the process of recording and organizing your business's day-to-day financial activity. The goal is to keep an accurate, current record of revenue, expenses, assets and debts in order to gain insight, support regulatory compliance and simplify tax preparation.

Common bookkeeping tasks include:

• Recording sales, payments and expenses
• Categorizing transactions
• Sending and tracking invoices and bills
• Reconciling bank and credit card accounts
• Organizing receipts and other supporting documentation
• Preparing financial reports  
• Tracking employee payroll and contractor payments

If your business finances are relatively straightforward, accounting software can help you keep your books organized and give you useful insights into revenue and spending.

QuickBooks Free offers a no-cost way to track income and expenses, organize transactions and run core financial reports. Customers don't need to share a credit card number and, unlike a free trial, the plan does not expire.

Bookkeeping is foundational to many financial tasks, from filing taxes to applying for a business loan. Good bookkeeping should help you:

1. Understand how your business is performing: Your bank balance shows how much cash you have on hand, but it doesn't tell the full story. Accurate bookkeeping lets you compare revenue and expenses, determine your business's profitability and identify trends over time. 

You can see what's working and also flag areas that might need your attention.

2. Manage cash flow: Keeping track of what you've earned, what you owe and what customers still need to pay enables you to better anticipate when cash may be tight. These insights inform everyday business decisions, like whether you can afford new equipment or hire a contractor.

3. Prepare for tax time: Recording and reviewing receipts, invoices, payroll and other records throughout the year makes it easier to account for your business income and identify deductible expenses.

4. Support financing applications: If you apply for a business loan or outside funding, you'll need to provide a lender or investor with financial reports that show how your business is performing.

Once you understand what bookkeeping involves and why it matters, you'll need to decide how you'll record transactions and build a routine.

1. Separate your business and personal finances

Even if you're just starting out, a dedicated business bank account makes it easier to track earnings and expenses without sorting through personal bills.

QuickBooks Free lets you connect a dedicated bank account and automatically import transactions instead of entering each one manually.

2. Choose where you'll keep your books

You might be one of the 13% of business owners in the QuickBooks survey who still rely on manual bookkeeping. But, especially as your business grows, working with scrap paper and Excel spreadsheets can be time-consuming and error-prone.

If budget is a concern, QuickBooks Free organizes transactions, receipts and invoices and generates core financial reports. As your business needs grow, you can migrate your data to QuickBooks Online and subscribe to a paid tier with more options. 

3. Determine your bookkeeping system

There are two basic bookkeeping systems: 

• Single-entry bookkeeping: You record each transaction once, a simpler option that may work for a small business with relatively few entries.
• Double-entry bookkeeping: Each transaction affects at least two accounts, with corresponding debit and credit entries. The total debits must equal the total credits, providing a built-in check on the accuracy of your books.

Double-entry bookkeeping is more involved, but many accounting software platforms use this method behind the scenes. QuickBooks Free supports double-entry bookkeeping fundamentals by generating balance sheets and profit-and-loss reports.

4. Choose an accounting method

Your bookkeeping system determines how you record your transactions, while your accounting method determines when you record them.

There are two main accounting methods:

• Cash basis accounting: Income is generally recorded when you receive payment and expenses when you pay them. For example, if you send a client an invoice in October and they pay it in November, you would record the income in November.
• Accrual basis accounting: You record income when you earn it and expenses when you incur them, even if money hasn't changed hands yet. So, if you send a client an invoice in October, you record the income in October, regardless of when they pay the invoice.

Cash basis accounting is often more straightforward because it closely follows the money moving through your accounts.

Accrual basis accounting can be more complicated because it requires you to keep track of what customers owe you (also known as accounts receivable) and your outstanding bills (or, accounts payable). But it can provide a more holistic view of your business's finances at any given moment.

Keep in mind that the accounting method you use can affect how you report income and expenses for tax purposes. In addition, tax regulations may affect which method you can use or when you can change methods.

5. Set up categories for your transactions

In accounting, the list of categories used to organize financial activity is called a chart of accounts. It typically groups transactions into broad categories, like assets, liabilities, equity, revenue and expenses, each with more specific subcategories.

For example, under "expenses," you could have:

• Office supplies
• Software subscriptions
• Travel
• Professional services
• Equipment
• Marketing

Use categories that make sense for your business and apply them consistently.

6. Record transactions and keep supporting documents

Now that you've set up your method, you're ready to start recording your financial activity.

Be sure to consistently record sales and other revenue, whether you send an invoice or customers pay you at the point of sale. If you invoice, keep tabs on outstanding payments.

QuickBooks Free currently allows up to two invoices per month and mileage tracking for up to five trips per month. If you qualify for and enable QuickBooks Payments, though, you can send unlimited invoices.

You'll do the same with expenses — record purchases and bills, categorize them and note any balances you still owe vendors. Don't forget about transactions that won't automatically appear in your bookkeeping system, like a cash purchase or an expense paid from a different account.

Keep the documentation behind these transactions organized, too. This can include receipts, customer invoices, vendor bills and account statements. 

7. Keep a regular bookkeeping schedule

Whether it's once a week or once a month, set aside time to review anything that still needs attention — including unpaid invoices, missing transaction details, receipts that need to be uploaded or charges that you don't recognize.

How often you need to check your books depends on your business type and size. The goal is to keep them current, so you're not trying to reconstruct months of financial activity later.

8. Reconcile your accounts and review reports

Even if your books are current, anomalies and errors can creep in. Periodically check that your records match the activity shown on your bank and credit card statements, a process known as reconciliation.

If you use a spreadsheet, that can mean manually comparing your entries with your account statements and looking for missing or duplicate transactions or incorrect amounts. Accounting software can do a lot of the reconciliation for you, but you should still review the information for accuracy.

Once everything lines up, use the data you've compiled to take a broader look at your financial health. QuickBooks Free includes three core financial reports: profit and loss statements, balance sheets and QuickReports, which give you a snapshot of key activities, like revenue, invoices and cash flow.

Reviewing reports regularly helps you identify trends, understand how your business is performing and catch cash-flow crunches before they become too difficult.

If your finances are relatively straightforward, you may be able to balance your own books. But if you're struggling to keep your books current, it may be time to work with a bookkeeper or accountant, whether that's a full-time hire or consultant. A professional can also help with more complex needs, like handling payroll, preparing tax filings, dealing with multiple entities or accounts, or producing financial information for loan applications.

You can also take a hybrid approach: handle day-to-day bookkeeping yourself and have an expert review your books periodically or prepare your tax return.

Balancing the books means more than just recording transactions. You'll need to choose bookkeeping and accounting methods that fit your business needs and working style, organize financial activity consistently, and regularly check that your records are accurate.

QuickBooks Free offers a no-cost option for freelancers, solopreneurs and new business owners who want to move beyond spreadsheets. As your business grows, your bookkeeping needs will likely become more complex, and you may want more advanced software or professional help.
