You don't need to be an accountant. You need to understand these five things.
Most small business owners either ignore their books until tax time or hand everything to an accountant and hope for the best. Neither approach gives you control of your business. Here are the five things you actually need to understand.
Revenue is everything that comes in. Profit is what's left after expenses. Most small business owners know their revenue but have only a vague sense of their profit. Knowing your profit margin — and whether it's going up or down — is the most important financial metric you have.
A business can be profitable on paper and still run out of cash. This happens when clients pay slowly, expenses are due before income arrives, or when a business grows faster than its cash can support. Tracking when money actually hits your account (cash flow) is different from when revenue is earned (profit), and both matter.
Every legitimate business expense reduces your taxable income. Common deductible expenses include tools and equipment, vehicle use for business purposes, home office (if you work from home), software subscriptions, professional development, and business meals (50%). None of these matter if you don't track them.
If you're self-employed and expect to owe more than $1,000 in federal tax for the year, the IRS expects you to pay estimated taxes four times a year (April, June, September, January). Missing these payments results in penalties. A general rule of thumb: set aside 25-30% of every payment you receive.
This is the revenue level at which your income exactly covers your expenses. Knowing your break-even number tells you how much business you need to stay viable and how much runway you have if revenue drops.
QuickBooks and Xero are the most widely used accounting tools for small businesses that want to manage their own books. Wave is a strong free option for simpler situations. Bench provides a real bookkeeper if you'd rather not do it yourself.
