Compatibility Group

A Compatibility Group is the set of vehicle models, engines, model-years, and trim variants that share a given part. It is the basis of fitment: a buyer asks not for a specific OEM number but for a part that fits their car, and the catalogue must answer with every variant that shares the same component. Compatibility groups are how online channels like eBay Motors and PartVisor surface fitment to buyers, and they are the reason a generic e-commerce push is rarely enough for used-parts retail. Sustain360 holds compatibility against each part record and propagates it to every channel that supports fitment metadata. The group is built from VIN-decoded vehicle attributes joined to a parts taxonomy; operators rarely curate the group by hand. The same compatibility data drives the picking and counter workflows — a sales operator can ask the platform whether a part on the shelf fits a buyer's car, and the platform answers against the same group used to publish the listing.
