Discover Your TRUE Profit Per Sale

Most e-com owners think they know their margins... they're usually wrong by 40-60%

Cost Breakdown Per Sale

What does this actually mean?

Think of it like this: you sell something for £100. After the product, shipping, ads and every other variable cost, you have £0.87 left per order.

Across your 1000 monthly orders that is £869 a month, or £10,428 a year, to cover rent, bills, fixed staff, insurance, software - and then profit.

This is the money available before you pay a single fixed overhead.
