Features
Automotive fitment tool for ecommerce sellers
Automatically match vehicle-specific parts with the correct make, model, year, and trim — so customers only see parts that fit, and you cut fitment-driven returns.
From catalog to accurate fitment everywhere
SellerChamp gives automotive sellers a structured system to organize parts, attach fitment data, and keep compatibility accurate across every sales channel.
1. Import your automotive catalog
Upload inventory via CSV, API integrations, or marketplace sync with Amazon, eBay Motors, Walmart, Shopify, and more.
2. Map vehicle compatibility
Attach standardized fitment attributes — year, make, model, trim, engine, submodel, and more — so each part is tied to the vehicles it supports.
3. Sync across marketplaces
Push compatibility data to connected channels from one place instead of updating fitment separately on every marketplace.
