Since eBay's attribution change, Promoted Listings can bill you on sales that used to be organic — many sellers went from 40% attributed to 90%+ overnight. RateTamer audits your own eBay data per SKU and tells you exactly which rates to cut, which items to opt out, and which ads actually earn.

Everything RateTamer analyzes is data eBay already gives you — it's just scattered across reports nobody has time to join. We do the forensic accounting.
Export your transaction report from Seller Hub (Payments → Reports) and drop the CSV into RateTamer. It parses orders and ad-fee lines right in your browser — nothing is uploaded anywhere.
RateTamer builds your pre- and post-January-13 baseline: which items sold organically before but now carry ad fees on every sale. That gap, in dollars, is your monthly waste number.
Every SKU gets one concrete action: cut the rate to X%, opt the listing out entirely, or keep it — the ads are genuinely earning. Apply the changes in Seller Hub and next month's bill shrinks.
We built this because sellers are angry, and angry customers deserve honesty, not another tool overpromising.
You can't get January back. You can stop paying it again every month.
The 90-day audit is free forever. Subscriptions add per-SKU depth, weekly drift alerts, and the billing-error credit finder — priced so one month of recovered fees pays the whole year.
Today's auditor runs on CSV exports. The connected version signs into eBay via official OAuth, audits automatically every week, and emails you when new waste appears. Join the waitlist and lock founding pricing — $19/mo for life, any tier.
✓ You're on the list. We'll email you when account connection opens.
The current auditor runs 100% in your browser — your CSV is parsed locally and never uploaded to any server. When the OAuth version ships, it will use eBay's official APIs with read-only scopes, and you can revoke access anytime from your eBay account.
Yes — all the data is yours, sitting in Seller Hub. If you enjoy joining transaction exports, building pre/post baselines per SKU, and re-checking monthly for drift, a spreadsheet works. RateTamer exists because most sellers would rather spend that time sourcing and listing.
Maybe someday — sellers have been asking since January. Until then you're billed under the current rules every month. And even before this change, rate optimization per SKU was worth real money; the attribution change just made the stakes obvious.
It's an estimate, and we label it that way. It's built from your own history: items that sold at a steady organic rate before January 13 and now show near-100% attribution with flat sales are, most plausibly, paying fees on demand that already existed. We show the assumptions behind every number.
No. RateTamer recommends; you decide and apply changes in Seller Hub. When the connected version ships, auto-apply will be strictly opt-in, per SKU.
