Seller intelligence is the identification of every seller listing your products across marketplaces, the classification of each as authorised, unauthorised, cross-border or retailer-driven, and the estimation of how much volume each one is actually moving.
Every seller on your listings, classified
Lupa detects each seller across Amazon, eBay, Walmart and 18+ marketplaces, and checks them against your authorised seller list. Channel volume is broken down by seller type — authorised, unauthorised, cross-border and retailer-driven — so you can see where your sales are actually coming from.
Seller-level sales attribution
The question is not how many unauthorised sellers exist. It is which ones are material. Lupa produces the best available estimate of units sold by each seller per day, using a confidence-based methodology built on observed stock movements, Buy Box status, pricing position and marketplace signals.
Confidence, not guesswork
Where sales can be directly observed, they are attributed as confirmed. Where stock visibility is limited — because a seller caps inventory, or because of a temporary data gap — Lupa applies conservative inference rules rather than inflating the number. Brands make expensive decisions on this data. It has to be defensible.
New seller detection
Unauthorised sellers appear, sell through inventory, and cycle accounts. Lupa flags new sellers as they arrive on your listings, so you find out while there is still stock to trace rather than after it has gone.
Cross-border and grey market signals
Sellers moving regional inventory into markets it was never priced for are identified and flagged, so leakage is caught before it becomes structural price erosion.
