Avoid bad FBA inventory decisions before you place a purchase order.
MarginIQ stress-tests supplier quotes, landed cost, Amazon fees, PPC, refunds, and risk so you know whether a product is launchable before inventory cash is committed.
It is not just a margin calculator. It is a pre-PO launch decision engine for deciding whether a SKU deserves inventory cash.
