About FortressScore
Know if an Amazon listing is beatable before you wire a factory.
FortressScore adds one panel to any Amazon product page:
LANDED MARGIN AGAINST REAL COMPS
The product image is matched on Alibaba in a background tab, the results are scored for whether they're actually the same product, and the median supplier price flows into a full landed-cost model: freight, duty, placement, FBA fee by size tier, referral, PPC, returns. Net per unit, margin, ROI, breakeven price, cash needed for the MOQ. Every number is editable and the table recomputes.
EDGE REPORT FROM CRITICAL REVIEWS
Up to 100 critical reviews, pulled through your own Amazon session, become weak spots and strong spots. Each weak spot is turned into a concrete spec to demand, one question that separates a real factory from a trading company, and what a third-party inspector should test before shipment. Strong spots tell you what you must match. Copy any question with one click.
FORTRESS SCORE
One 0 to 100 read on how hard the listing is to displace, from its review base, its age, and whether its biggest complaint has ever been fixed.
SUPPLIER TRACKER
Save products and suppliers with quotes, MOQ, lead time, sample cost, status, and notes. The list you actually come back to when it's time to order.
