Amp Analysis works out what you actually keep once product costs, card and marketplace fees, delivery, packaging, ad spend and refunds come off. See it for today, 7 or 30 days, and where your money went. Every product gets an Amp score from 0 to 100 and a plain verdict. When a product loses money, Amp shows the price to charge or the most to pay your supplier to fix it. Check a new product's profit before you stock it, and read a short report of last week's sales.
