Analysis
Buy-list analyser
Drop in a supplier's price list and an Amazon data export. This works out what each line actually earns after every cost, and rejects the ones that don't clear your thresholds. Everything runs in your browser — no file leaves this computer.
Supplier price list
Applies to every product in this list, and travels with them onto the watchlist and the opportunities board.
Amazon data
Optional — skip if your price list already includes selling prices.
Pulls the Amazon side straight from the Keepa API using the barcodes in your price list, so you don't need to export anything by hand. Roughly one Keepa token per product, from an allowance of 1200 that refills at 20 a minute — so a 100-line lookup costs about a twelfth of the bucket and five minutes of refill. Nothing is fetched until you press the button, and the filters below cut the list first.
