Rithum, the company ChannelAdvisor became after merging with CommerceHub, is an enterprise platform for managing listings, inventory and orders across many marketplaces. Dealer Portal is a smaller, dealer-focused system built around Lightspeed DMS. Here is how they line up for a powersports parts department.
Large brands and retailers selling on many marketplaces at high volume, who want enterprise reporting, a long list of channel integrations and an account team, and who are comfortable with a quoted contract that can include a GMV-based fee.
Powersports dealers on Lightspeed who want parts and major units synced to Amazon, eBay and their own parts website, orders delivered to Lightspeed EVO, and shipping, email and texting in the same login, for one flat monthly price.
