Unauthorized Seller Enforcement
Verify seller status, surface unauthorized storefronts, issue notices, and remove violators from third-party marketplaces with less manual review.
The problem
Unknown sellers list your products without authorization, often with bad service and pricing.
Diverted inventory shows up where it shouldn't, undercutting your authorized channel.
Your real partners lose trust when violators aren't dealt with quickly.
