Deal Analysis Report
Profit breakdown, fees, risk flags, and a buy/pass recommendation.
Every section is designed to answer one question fast: should you buy this deal, and will it actually make money?
Fees, transport, and realistic resale ranges—so you stop buying “maybe” deals.
Analyze in seconds, send an offer script instantly, and lock in the deal.
Track inventory, performance, and what actually makes you money.
The same three outcomes come up repeatedly: faster decisions, tighter margin control, and better deal timing.
