Costco Wholesale
The Issaquah, Washington warehouse club, founded in Seattle in 1983 and merged with the club format's inventor, Price Club, in 1993, that runs the simplest supply chain in large-scale retail: ~4,000 active SKUs (company figure) against tens of thousands in a supercentre, goods moved on full pallets through cross-dock depots to warehouses where the pallet is the display, a capped markup (~14% on branded goods, ~15% on its Kirkland Signature private label, company policy) and a membership fee that supplies a large share of profit. Limited assortment means each item sells in enormous volume and turns before Costco has paid for it, so suppliers largely finance its inventory — a near-zero or negative cash conversion cycle as the business model. In fiscal 2026 (52 weeks to 30 August 2026) Costco reported net sales of ~$297bn, membership fees of ~$5.9bn (+11%) and net income of ~$9.2bn, with 939 warehouses and 84.1m paid members renewing at 92.3% in the US and Canada (company). Its supply-chain story turns on cost to serve through limited assortment, and its few failures — a rocky merger, an expensive 2021 shipping charter — were cheap relative to the model's resilience.
