Costco fulfillment
Darwynn is a Costco vendor of record and fulfills Costco orders for ecommerce and wholesale brands from more than 15 locations across Canada and the USA. Its integration with Rithum, formerly CommerceHub, connects Costco orders directly to Darwynn's inventory, preparation and shipping.
How a brand goes live on Costco.ca
Darwynn is a Costco vendor of record. A brand with approved products can launch on Costco.ca through Darwynn, and a brand already selling there can move its Costco fulfillment to Darwynn while its current setup stays active until the cutover date.
- Vendor of recordCostco approves the products first, and the brand agrees pricing with its buyer directly. Once the items have Costco item numbers, Darwynn can act as the vendor of record, holding the vendor account and signing the item agreements on the brand's behalf.
- Item setupThe brand completes one form for each approved item: shipped dimensions and weight, landed cost, product content in English and French and high-resolution images, plus nutrition and allergen panels for food. Darwynn reviews every form before it goes to Costco.
- Integration and locationsThe brand chooses the Darwynn locations it will ship from, ideally one in the east and one in the west. Darwynn maps the items in its Rithum integration, links the shipping account for each location and tests the order flow with Costco.
- Launch and promotionsOnce the inventory has arrived and Costco confirms the setup, the items go live and orders arrive in Darwynn OMS with the brand's other orders. After launch, Darwynn plans inventory, kitting and capacity around Costco's promotions, which drive most Costco.ca sales.

Costco kitting and variety packs
Darwynn builds variety packs and bundles for Costco to the agreed assortment and pack configuration, applies labels, re-barcodes products and prepares retailer-specific case packs where the program requires them.
Packs are assembled in advance and stored, or as orders arrive, as the program calls for. Brands supply packaging and printed materials, or Darwynn helps source materials and arrange printing. Kitting and customization
Wholesale distribution and freight to Costco
Darwynn also ships wholesale orders to Costco distribution centres, with case packs, pallets and labels built to Costco's receiving requirements.
Freight moves by LTL or full truckload with Costco-approved carriers. Darwynn Dispatch books the carrier and the delivery appointment, and Darwynn submits the ASN for every shipment. When the carrier collects, the team records the outbound checklist, photographs and handover time, so the brand sees the condition each shipment left in.
