Network onboarding

Costco Dropship (via Commerce Hub) is routed through CommerceHub

Stacksync maintains a certified CommerceHub connection covering 2 trading partners across 2 channels. Onboarding with Costco on this channel reuses that connection — no separate VAN contract or certification cycle.

CommerceHub, now part of Rithum, operates the dropship and marketplace network used by large North American retailers to trade with their suppliers. Retailers mandate it for dropship programs: suppliers receive orders and inventory requests and return shipment and invoice data through the platform. Its OrderStream service handles retailer integration over EDI and file-based connections, with a structured onboarding workflow of connection setup, data collection, quality checks, and activation.

Connecting via CommerceHub
  1. The sponsoring retailer enables the supplier account; contact CommerceHub partner setup (partnersetup@commercehub.com) to request credentials and declare your format, for example XML over SFTP, EDI, or a VAN connection.
  2. Obtain the retailer's test plan and message-format guides from CommerceHub, and configure warehouse/facility IDs and SKU data in your integration.
  3. Run the retailer's test plan: load test orders over the test SFTP endpoint, generate responses, and complete the required manual actions in the testing portal at test.commercehub.com.
  4. After CommerceHub certifies the test orders, cut over to production by switching from the -test SFTP host to the production host (for example mystore.sftp-test.commercehub.com to mystore.sftp.commercehub.com).

Testing: Certification is required per retailer connection. Suppliers execute the retailer's test plan and message-format documents, submit test orders and responses, and complete manual actions in the CommerceHub testing portal; CommerceHub reviews the results and may require changes or additional test orders before certifying the connection for production.

Timeline: No official public timeline. Certification runs per retailer and is paced by test-order review cycles with CommerceHub support; portal-only setups are faster than integrated EDI connections, which are paced per retail channel by the retailer's test plan and CommerceHub's review of submitted test orders.

Costco Dropship (via Commerce Hub) questions

How is the Costco dropship channel different from Costco's wholesale channels?
It runs through the CommerceHub network and adds dropship-specific documents: the 846 inventory inquiry/advice for stock feeds, the 820 payment/remittance advice, and the 180 return merchandise authorization, alongside the 850, 856, and 860.
Do I need to send inventory updates on this channel?
Yes. The 846 inventory advice is part of the channel's document set; dropship programs typically rely on it to keep the retailer's view of your available stock current.
