What it does
Your real profit on each sale, after every cost that eats into it, and whether what you pay to win a customer makes sense. Many sellers see revenue and miss how thin the margin is once ads and fees are in. You give your price, product cost, shipping both ways, warehouse fees, card fees and ad spend. The skill adds them up item by item: a card fee of a percentage plus a fixed amount, ads often 20 to 40 percent of sales, return costs, and free shipping if you offer it. It then shows margin per order and compares what a customer is worth over time with what it cost to win them.
