GMV in a multichannel home goods engagement
8 channels
Connected through one orchestrated operation
Senior-led
Brand-side operators—not junior handoffs
Client results reflect a multichannel engagement, not Costco-only results or a guarantee of future performance.
Keep your Costco channel working for your business.
Inconsistent product data, unclear operational ownership, and margin blind spots create work without creating profitable growth. We assess your current channel and build a prioritized plan around the relationship and requirements that actually apply to your brand.
Costco 1P & 3P experience
Review the assortment and commercial terms relevant to your Costco relationship. Coordinate product data, supply planning, and execution responsibilities around the requirements shared with your team. Our experience also covers 3P operations; we keep each model’s commercial terms, catalog ownership, fulfillment responsibilities, and reporting distinct.
Clean catalog & product content
Review your Costco assortment, attributes, imagery, and product content against the requirements provided to your team. Establish a clear correction process and ownership for ongoing updates.
Pricing discipline & margin visibility
Bring commercial terms, product costs, fulfillment, and channel expenses into the same view. Prioritize assortment and operational decisions around contribution margin rather than revenue alone.
Launch & recovery support
Assess readiness, organize catalog and operational corrections, and coordinate inventory, order, and fulfillment responsibilities with your team and existing partners. Retailer decisions remain with the retailer.
Partner-enabled 3P connections
Our familiarity with many additional 3P channels comes through technology connections via partnerships with ChannelEngine or Rithum ChannelAdvisor. We help assess supported connections and coordinate product data, inventory, and orders with your team. Connection availability, retailer approval, and seller eligibility must be checked for each channel; a technology connection is not a guarantee of access.
“We went from four teams rebuilding the same content to one platform that feeds every channel. It changed how we operate.”

Costco marketplace management questions
What experience do you bring to Costco?
Wishbone is familiar with Costco across both 1P wholesale and 3P models. In 1P, your brand sells wholesale to the retailer for resale; in 3P, your brand operates as a third-party seller under the applicable channel arrangement. We bring experience in both to catalog preparation, commercial planning, operational coordination, and margin visibility. This does not imply an open marketplace or that we can secure a retailer relationship.
Is this an open 3P marketplace service for Costco?
Not necessarily. Wholesale supply, dropship arrangements, and third-party marketplace selling have different commercial and operational models. We start by confirming your Costco relationship and the options available to your brand, rather than assuming there is an open marketplace or that a connector provides access.
How do ChannelEngine and Rithum ChannelAdvisor fit in?
Our familiarity with many additional 3P channels comes through technology connections via partnerships with ChannelEngine or Rithum ChannelAdvisor. We help assess supported connections and coordinate product data, inventory, and orders with your team. Connection availability, retailer approval, and seller eligibility must be checked for each channel; a technology connection is not a guarantee of access.
Can you guarantee a Costco listing or supplier agreement?
No. Costco controls supplier selection, seller approval, product eligibility, and listing decisions. Wishbone supports preparation and execution within the processes and relationships available to your team.
Can you work with our current team?
Yes. Senior-led operators work alongside your commercial, catalog, operations, and technology teams, as well as existing agencies and integration partners. We define the scope, ownership, and fees before starting.
What does Costco marketplace management cost?
Your introductory 15-minute consultation is free. Engagement fees depend on catalog size, channel readiness, and the launch, recovery, or ongoing support you need. We agree scope and fees before starting; media spend and retailer fees are separate.
