Bookkeeping Basics: Understanding Revenue & Income

We’re continuing our Bookkeeping Basics series, and today we’re talking about Income (also called Revenue) — one of the most important parts of your financial picture.

Income is exactly what it sounds like: money coming into your business from selling products or services. But depending on the type of business you have, income can show up in a few different ways. Understanding how your revenue is categorized makes your financial reports clearer and helps you make better decisions.

What Is Income / Revenue?

Income (or revenue) represents sales generated by your business.
This could be from:

• Selling products
• Providing services
• Renting space or property
• Earning interest
• Selling business assets

On your Chart of Accounts, income accounts are typically grouped together and often marked with the number 4.

Common Types of Income Accounts

1. Product Income
   This includes revenue from any physical or digital products you sell.
   Each product category can be customized based on your business needs.
2. Service Income
   This is income earned from providing services.
   For service-based businesses (like bookkeeping, therapy, consulting, or wellness services), most or all revenue falls into this category.
3. Rental Income
   If you own property and rent it out — or if you sublet part of your office space — that income should be tracked separately as rental income.
4. Interest Income
   Even small amounts of interest earned on savings or business accounts count as income and should be recorded here.
5. Sale of Asset Income
   If you sell business equipment, machinery, or other assets, the income from that sale is tracked separately from regular sales.

Why This Matters

Breaking income into the right categories helps you:

• Understand where your money is coming from
• Track business performance more accurately
• Prepare clean, organized financial reports
• Make tax time much smoother

While there are many possible income accounts, these are the most common ones most businesses use. Your bookkeeper or accountant can help customize them, but knowing the basics gives you clarity and confidence when reviewing your numbers.
