Small Business Budgeting 101: Start Smart, Whatever You’re Selling

Starting a side hustle or small business is exciting—but the numbers behind it matter just as much as the passion that drives it. Whether you’re selling plants, baked goods, crafts, or something entirely different, a simple budgeting habit can be the difference between a fun hobby and a profitable business.

If you’re not sure where to start with the financial side, this guide walks you through the basics.

1. Know What You’re Spending
Before you think about profit, you need to know your expenses. It could be supplies, packaging, delivery fees, or even electricity. For example, if you’re selling potted plants, your costs might include soil, pots, tools, and fertilizers. Add those up. You can’t price your products properly if you don’t know what they’re costing you.

2. Understand Your Break-Even Point
Once you know your costs, ask yourself: how much do I need to sell to recover them? If you spend $40 on materials and each item earns $4 in profit, you need to sell 10 just to break even. Everything after that is actual income.

3. Keep Track of Every Dollar
Don’t rely on memory. Use a basic spreadsheet or a budgeting app to record your expenses and income. Even if your business is small, keeping track now makes it easier to scale later—and it helps you see if you’re really earning, or just breaking even.

4. Set a Budget for Growth
As things pick up, plan ahead. Want to join a local fair? Start an online shop? These things cost money. Set aside a portion of your earnings for future investments in your business. That way, you’re not caught off guard when opportunity comes.

5. Don’t Skip the Financial Habits
It’s tempting to focus only on the fun side of your business—designing, creating, or interacting with customers. But even basic financial awareness builds long-term success. Budgeting helps you make better decisions, stay organized, and build confidence in running your own thing.
