Scale indicators8 records

Emerging players

• RevolutionParts: RevolutionParts provides ecommerce and parts ordering solutions for automotive dealers and parts departments. It is an emerging player focused on dealer-channel parts sales, partially overlapping Nexpart's OE and aftermarket parts marketplace value proposition.

Broad incumbents

• AutoZone Commercial: AutoZone is one of the largest US auto parts retailers, with a commercial program serving professional installers. Its store density, inventory, and credit programs position it as a broad incumbent that competes with Nexpart for the same professional repair shop business.
• Advance Auto Parts: Advance Auto Parts is a large US auto parts retailer with a professional program (Advance Professional) serving repair shops. Its omnichannel strategy and store footprint make it a comparable broad incumbent to Nexpart in serving the same professional buyer segment.
• O'Reilly Auto Parts: O'Reilly Auto Parts is a leading US auto parts retailer with a strong professional/commercial program and a distribution network for next-day delivery. It competes with Nexpart for professional buyer wallet share and is a key participant in the aftermarket distribution channel.
• Amazon Business: Amazon Business is the B2B arm of Amazon, offering industrial supplies, MRO, and increasingly automotive parts procurement with Prime-style logistics. Its scale, logistics network, and buyer relationships make it a broad incumbent threat to dedicated B2B parts marketplaces like Nexpart.
• NAPA Auto Parts: NAPA is a major US auto parts distributor and retailer with a deep store network and a heavy-duty (NAPA Heavy Duty) program. It is both a key supplier on Nexpart's network and a competing channel for professional parts buyers, making it a critical incumbent peer.

Direct peers

• PartsTech: PartsTech is a B2B automotive parts ecommerce platform that aggregates inventory from multiple suppliers for repair shops. It is the most direct competitor to Nexpart, offering a similar single-login multi-seller ordering experience and shop management system integrations.
• eBay Motors: eBay Motors is the automotive parts and vehicle marketplace run by eBay, the apparent parent of WHI Solutions / Nexpart. It overlaps directly with Nexpart in selling aftermarket and OEM parts to professional buyers and consumers, creating an in-house competitive dynamic.

Others

• Mitchell1: Mitchell1 is a leading provider of automotive repair information, shop management systems, and estimating software used by US repair shops. It is a certified SMS partner distributed through Nexpart, but also a complementary data and workflow provider in the same automotive aftermarket ecosystem.
