See whether a healthy ROAS is hiding halo sales that lose money.
Included in the $9.00 Shelf Kit
Amazon Sponsored Display sellers, agencies, and agents checking whether the products customers actually bought after an ad contribute margin before a human changes spend.
Delivery: usually a structured result, workbook, or ZIP depending on the tool.
Friday performs arithmetic only on the Sponsored Display purchased-product rows, unit economics, ad spend, and contribution floor you supply. It reads no Amazon account, report, campaign, order, or shopper record. A purchase is called direct only when the purchased ASIN equals the advertised ASIN; every other purchase is halo, which does not prove the ad caused the sale or that any purchase is incremental. Contribution, margin, ROAS, and net-after-ad figures are arithmetic on supplied values, not forecasts, and the supplied floor is a seller decision, not an Amazon standard. Friday does not publish listings and never changes a campaign, bid, budget, price, or listing.
