The problem

Unauthorized sellers cost you more than sales:

Rogue resellers

Unknown sellers list your products without authorization, often with bad service and pricing.

Gray-market diversion

Diverted inventory shows up where it shouldn't, undercutting your authorized channel.

Channel conflict

Your real partners lose trust when violators aren't dealt with quickly.

Our proactive approach

Verify, surface, and remove unauthorized sellers.

You can't enforce what you can't see. VantageBP resolves marketplace sellers against your authorized list, surfaces the unauthorized storefronts, and runs the enforcement workflow — verification requests, notices, and takedowns — backed by a database of 100,000+ identified resellers and real investigative work.
