A profit & loss statement, or P&L, is one of the most useful reports a business owner can read regularly, but it's often skimmed and set aside because the terminology feels intimidating.
Revenue
This is everything your business earned in the period, before any costs are subtracted. It's the top line for a reason: everything else flows from it.
Cost of Goods Sold
The direct costs tied to producing what you sell. Subtracting this from revenue gives you gross profit, a key measure of how efficiently you're delivering your product or service.
Operating Expenses
Rent, payroll, software, marketing, and everything else it takes to keep the lights on. These are usually where the biggest opportunities to improve margin hide.
Net Income
What's left after every expense is accounted for. This is the number that ultimately answers the question, "did we make money?"
Reading your P&L monthly, not just at tax time, is one of the simplest habits that separates businesses that grow intentionally from those that are just along for the ride.
