Quick answer
To become a Costco supplier, contact the right buying office — corporate buyers for non-food, regional buyer offices for food and sundries — and submit a vendor inquiry with your business plan, certifications and insurance. The model is unforgiving on scale: expect 10,000+ units per SKU production capacity and pricing around 15% below other retail channels. For small brands, Roadshows and Special Events are the real entry route — lighter requirements, in-warehouse proof of demand, and a track record Costco buyers trust.
Costco's model is the inverse of a supermarket: a tiny number of SKUs (about 4,000 per warehouse) bought in enormous volume and sold at deliberately thin markups to members. Winning a pallet at Costco is transformative — and structurally hard, because every item must earn extraordinary velocity. The buyer's question isn't "is this good?" but "can this sell a warehouse-load a week at a price 15% below everyone else?" Roadshows exist precisely so smaller brands can answer that with evidence.
Non-food and sundries route to corporate buyers; food and sundries also work through regional buying offices by geography. Initial contact is a vendor inquiry with business plan, certifications and insurance documentation. Costco buying is relationship-driven and skeptical of unproven volume claims — evidence first.
Costco Roadshows (temporary in-warehouse selling events, typically 10–14 days) have far lighter requirements than full vendor status. You staff a table, sell your product, and generate the exact data — units per warehouse per day — that makes a buyer conversation concrete. Many permanent Costco items started as Roadshow successes.
Costco frequently tests items in a single region before national rollout. Pitching a regional buyer for a regional test lowers the volume bar and matches how Costco itself de-risks new items — align with it rather than pitching national on day one.
