Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureProduct Fit Finder lets merchants build a guided compatibility selector for any industry — auto parts, powersports, electronics, pet supplies, sports gear, and more. Customers pick from configured options (like Brand, Model, Year or Size, Type, Style) and instantly see only matching products. No wrong purchases or returns. Set up levels, import data via CSV, and add the widget to any theme page in minutes.
Suppliers send fitment files every month, usually covering part of your catalog. Loading one should not mean wiping everything and starting over. Import a file and choose: add only, add and update, replace one brand, or replace just the listed parts. Replacing Brembo leaves Bilstein untouched. Before anything writes, you see what will change, including rows that could not be read and why.
