Expanding from Amazon to Walmart is a channel decision as well as a catalogue task. Start with the country you plan to sell in, the product economics and the operating work the launch creates.
Model the product economics
For each pilot SKU, record selling price, product cost, referral fees, fulfilment costs, inbound freight, expected returns and advertising assumptions. Use current fees for Walmart Canada or the US as applicable.
Choose a fulfilment approach
Compare WFS with your own fulfilment or a 3PL. Use actual dimensions and weights, expected sales, storage duration and receiving requirements. Do not assume Canadian and US WFS programmes have identical fees, badges or rules.
Prepare the catalogue for Walmart
Check the required attributes, identifiers, images and item-setup rules for your category. Review publishing errors in Seller Center. Use pricing notices and the applicable policy to diagnose an issue, rather than assuming every unpublished item has the same cause.
Plan a controlled launch
Start with an assortment your team can support. Define who owns feeds, pricing, inbound shipments, advertising and returns. Review availability, conversion and contribution before adding more SKUs.
Rebuild the economics instead of copying Amazon
Use the Walmart selling price, applicable marketplace fees, fulfilment model, inbound freight, returns, advertising and product cost. Different programme structures and customer demand mean an Amazon P&L should not simply be relabelled.
Choose a pilot assortment deliberately
Start with products that have stable supply, clean product data and enough margin to absorb the new channel’s operating costs. A pilot should teach the team how catalogue, fulfilment and returns work before the full assortment is committed.
Plan inventory as a shared resource
Walmart demand competes with FBA, DTC and retail for the same stock. Define initial allocations and replenishment rules before the launch so one channel does not create shortages in another.
Assign recurring account ownership
Someone needs to own item status, WFS or merchant fulfilment, advertising, returns, cases and reconciliation. The expansion is not complete when the first listings publish.
Use the marketplace margin calculator and see Walmart Marketplace management.
Build a cross-channel operating calendar
Track Walmart launch tasks, inbound dates, promotions and replenishment alongside Amazon commitments. Shared suppliers and inventory pools mean a decision on one marketplace can create a shortage on the other.
Review what should stay different
Do not assume titles, images, promotions and fulfilment choices should be identical across Amazon and Walmart. Keep core product facts consistent while adapting the offer and operating model to the channel’s current requirements and customer behaviour.
Set channel-specific launch thresholds
Define the minimum contribution, inventory availability and operational readiness needed before adding a SKU to Walmart. This prevents the team from expanding simply because the item already exists on Amazon.
Review duplicated workload
Track whether the second marketplace creates new manual catalogue, case, reporting or reconciliation work. Use that evidence to decide where automation or additional ownership is needed.
Use a launch post-mortem
After the first 60–90 days, compare forecast, actual sales, fees, fulfilment, returns and workload. Use those findings to decide which SKUs or processes should expand next.
