VendorCo’s mission is to help business owners achieve success by developing and placing exciting, new products into Costco.

Getting products into Costco can be overwhelming, complex, and time-consuming. We provide the expertise, knowledge and relationships so busy business owners don’t have to figure it out themselves.

We also understand how difficult and time-consuming it is for Costco to whittle down the thousands of products that come across buyers’ desks every day.  That’s why we thoroughly vet our prospective clients, to not only select the most unique, exciting products, but to ensure readiness for Costco placement as well. 


We’re committed to helping businesses succeed by achieving Costco placement, at the same time doing business with 100% integrity and the greatest respect for our clients and Costco.
