Load your eBay data and RateTamer builds your pre/post-January-13 baseline, estimates fees paid on would-be-organic sales, and gives every SKU one concrete action.
In Seller Hub go to Payments → Reports → Transaction report, pick the last 6+ months (so we can see before and after Jan 13), download the CSV, and drop it here. Order and ad-fee rows are matched per item locally.
A synthetic reseller doing ~$9k/mo across 12 SKUs — clothing, sneakers, electronics — with the exact post-January-13 attribution pattern sellers are reporting. Same engine, same math as a real CSV.
No CSV handy? Pull these from Seller Hub's advertising dashboard (before/after values are on your campaign performance page).
Watch what happens at the January 13 line.
Same sales, suddenly "ad-driven."

For each item we compare two windows: before January 13, 2026 and after. An item that sold at a steady organic rate before (few or no ad fees) and now shows ad fees on nearly every sale — with flat or lower sales velocity — is most plausibly paying fees on demand that already existed. The waste estimate per item is its current fees × the share of attribution growth not matched by sales growth. Items whose sales genuinely rose with ads are marked KEEP and count zero waste. These are estimates, clearly labeled — eBay does not publish per-sale incrementality, and nobody outside eBay can compute it exactly. The point is direction and magnitude, and it's built from your own data.
CUT: Advertising dashboard → your campaign → edit ad rate for the listed item to the suggested %. OPT OUT: remove the listing from the campaign entirely — its buyers were finding it anyway. PAUSE: low-velocity items paying fees for stale clicks; remove and relist into ads only when velocity returns. KEEP: leave it alone — the ads are earning their fees. Re-run this audit next month: eBay's 30-day attribution window means changes take a few weeks to fully show up.
The connected version signs into eBay (official OAuth, read-only), re-audits weekly, catches new listings drifting into campaigns, and emails you when fresh waste appears. Founding waitlist members lock $19/mo for life.
