Your listings are invisible
to buyers right now.
eBay buyers filter by Year, Make, and Engine. Without compatibility data on your listings, you don't show up in those searches — and most serious buyers shop that way. Fathom scans your store, finds the gaps, and tells you exactly what to fix.
From gap to fixed in minutes.
We audit your store
We scan your eBay listings, extract part numbers, and cross-reference against our manufacturer catalog database — CDI, EMP, GLM — 25,000+ fitment records across Mercury, Yamaha, Johnson/Evinrude, and more.
You see the gaps
You get a private report showing exactly which listings are missing compatibility data and what engines they fit — part number by part number, with confidence scoring from manufacturer sources.
We deliver the fix
We send you an eBay-ready compatibility CSV for bulk import, or handle the upload for you. Your listings become visible to engine-specific buyer searches immediately.
Simple. No surprises.
