Today we’ll break down bookkeeping basics in plain English and shows how you can get started with a spreadsheet (Excel or Google Sheets). Doing your own bookkeeping in Excel not only helps you understand your finances but also organizes totals and receipts so your tax return can be completed more accurately, quickly and at lower cost.

What Is Bookkeeping?

Bookkeeping is the day-to-day practice of recording all your business's financial transactions so you have an accurate record of every dollar that comes in and goes out. Think of it as the transaction-level trail — sales, invoices, receipts, payments to vendors, deposits from customers, and bank records — that together form your financial records.

Bookkeeping is distinct from accounting: bookkeeping focuses on recording and organizing transactions, while accounting analyzes that organized data, creates financial statements, and helps prepare tax returns. You'll need clear, consistent bookkeeping records to produce reliable financial statements and to make tax time faster and less expensive. Without good bookkeeping, you'd be trying to run your business blindfolded!

Why It Matters

Many small business owners put off bookkeeping because it feels boring or overwhelming. In reality, good bookkeeping is one of the most useful tools you can build into your business — it gives you a clear picture of profits and losses and helps you make smarter choices with your money.

• You'll know exactly how much money you're making (or losing), so decisions about pricing and hiring are based on data, not guesswork.

• You can spot cash problems early — healthy cash flow means you can pay bills and invest in growth without surprises.

• Tax time becomes much less stressful: organized records and categorized expenses let you—or your accountant—prepare tax returns faster and at lower cost.

• You can make smarter business decisions (inventory, discounts, or marketing) because timely reports show what’s working.

• Getting loans or lines of credit is easier when you can provide clear financial statements and up-to-date records to lenders.

A Real-Life Bookkeeping Example

Clayton, runs a small bakery. Before he started a simple bookkeeping routine, he felt like he was always busy but never sure whether the business was actually profitable.

When Clayton started keeping track of his finances, he discovered something important: while his fancy cakes were popular, they actually cost more to make than he thought. His simple cookies, which he hadn't focused on, were bringing in most of his profit!

By tracking ingredients, sales, and other costs, Clayton could see which products were worth his time. He adjusted his menu to focus on high-profit items and raised prices on others. Within three months, his profits went up by 25%!

In this illustrative example, Clayton saw a meaningful improvement in profitability within a few months (results will vary by business). Importantly, because he kept clear records of income, expenses, and receipts in Excel, he could produce a simple profit and loss summary for each month — the same totals an accountant needs at tax time. That saved both time and money when preparing her tax return.

Without that bookkeeping habit, he might have kept focusing on the wrong products and faced cash flow stress despite working harder. Tracking income and expenses at the product level gave him the information he needed to make better decisions for the business.
