Online arbitrage rests on a simple principle: the same product never sells for the same price everywhere. Finding it cheaper in one place and reselling it where it's worth more means comparing, continuously, more sources than anyone could track by hand. That's what ArbitragePro+ does.
What ArbitragePro+ actually does
ArbitragePro+ continuously compares the catalog of thousands of supplier sources (B2B wholesalers, marketplaces, Shopify and WooCommerce stores, merchant feeds) against resale prices, surfacing only the net gaps that are actually exploitable — not a raw gap shown before fees.
As of publication, the database tracks 4,673 sources, including 1,348 qualified as accessible after manual verification (robots.txt, a usable catalog, confirmed currency and price). It holds over 6.1 million product references: around 831,000 matched by barcode (EAN/UPC/GTIN) and more than 5.2 million from stores that publish no barcode at all, matched by a compatibility engine.
Matching: EAN when it exists, compatibility otherwise
The simple case is the barcode: an identical EAN on two sources unambiguously means the same product. The frequent case, especially on Shopify, is no published barcode at all. ArbitragePro+ handles both: direct EAN matching when available, and for the rest a compatibility engine that cross-checks title, brand and image — with price used as a guardrail to rule out false positives rather than as a matching criterion.
The three-way loop with Analyzer+ and Profit+
ArbitragePro+ doesn't work alone. Analyzer+ decides whether a product is worth buying (projected margin, category, Amazon price history). ArbitragePro+ shows where to buy it cheaper. Profit+, currently in development, is meant to then measure what the purchase actually returned and feed that back: a product whose real margin collapses should drop out of the opportunities list rather than stay listed indefinitely.
