What you receive

  • Maximum affordable ad fee from the listing economics and contribution floor you supply
  • Economic maximum ad-rate percentage plus a conservative one-decimal screening guardrail

  • No-headroom, all-exceed, partial-exceed, and within-guardrail review bands
  • A stable listings-first review queue without account access or campaign changes

Who it is for

eBay sellers, agencies, finance teams, and ad operators screening seller-supplied Recommendation API guidance before a human chooses or changes a cost-per-sale ad rate.

Delivery: usually a structured result, workbook, or ZIP depending on the tool.

How it stays safe

Friday calculates only from the listing ID, optional SKU, eBay recommendation labels and rates, listing price, ad-fee basis, costs, fees, and contribution floor you supply. It reads no eBay account, API, report, campaign, listing, order, or buyer data and verifies no field. ITEM and TRENDING rates remain unverified eBay guidance—not an optimum, visibility promise, forecast, or bid recommendation. Friday does not publish listings and never creates, changes, or publishes a bid, budget, campaign, ad, or listing. A human must verify current rates, the true sale-amount fee basis, attribution rules, returns, taxes, and omitted costs before acting.
