Know your numbers: unit economics 101

If you don't know your profit per order, you're flying blind. Learn contribution margin and break-even ROAS before you spend a dollar on ads.

Unit economics is the profit math of a single order, and it's the difference between scaling and quietly going broke. You need contribution margin per order and the break-even ROAS it implies, so you know the most you can pay to acquire a customer. AI does the math on your numbers; it never invents a cost.

If you can't say your profit on one order, you can't tell whether ads make money or lose it. The two numbers that matter are contribution margin per order and the break-even ROAS it sets.

AI can run the full calculation from your inputs. You supply the real costs, because AI must never guess your COGS, shipping, or fees.
