CostRadar shows true net profit per BigCommerce order: revenue minus COGS, payment gateway fees, shipping, and returns. Connect from the BigCommerce control panel or from CostRadar Settings → Stores. After you authorize, we sync orders, catalog SKUs (for COGS), customers, and order payment transactions. Access is read-only: we do not change products, orders, or inventory in BigCommerce. Opening the app takes you to the standalone CostRadar app, where you see order-level P&L and product costs. If you also connect other stores you already run, they appear in the same portfolio. Plans are Free, Advanced, and Premium, billed in CostRadar via Stripe — not through BigCommerce App Marketplace billing. Support: hello@costradar.ai
