How the math works

Net profit = Revenue − COGS − Payment fees − Shipping − Refunds − Ad spend − Overhead.
Net margin = Net profit ÷ Revenue.
True ROAS (POAS) = (Net profit before ad spend) ÷ Ad spend — i.e. profit per ad dollar, the number that tells you if a channel actually pays for itself out of margin (not just revenue).

This is exactly what Shopify's analytics can't show you, because it doesn't know your costs. ProfitPeek pulls your orders, real fees, and refunds automatically and applies your costs for you.
