Walmart: moving 80 SKUs to WFS lifted margin 6 points

Self-fulfilled Walmart orders shipped in three to five days, so listings rarely showed the two-day tag, and 4% of orders ended in a shipping-related refund. Seller-fulfilled rates were also rising.

• Ranked the catalogue by velocity and size; the 80 SKUs that made 85% of units went to Walmart Fulfillment Services.
• Rebuilt shipping templates for the long tail that stayed seller-fulfilled.
• Re-priced the WFS SKUs against the fee difference instead of copying Amazon prices.

Two-day badge on all 80 WFS SKUs; shipping refunds fell from 4% to 0.6% of orders; net margin on the WFS group rose six points. Walmart sales grew 44% over the following quarter.

Why it worked

The delivery promise decides how a listing is displayed and how often orders end in a refund. Sending the fast movers to the marketplace's own warehouses fixed both at once. Pricing those items against their new fee structure, instead of copying prices from another channel, is what turned better service into better margin.

What to check on your own catalog

• Rank products by units sold and size. A small share of SKUs usually makes most of the orders.
• Compare the full cost of each route: fees, postage, late-delivery refunds and staff time.
• Keep slow or bulky items seller-fulfilled, with shipping templates you can actually meet.
• Set prices per channel. Fees differ, so the same price rarely gives the same margin.
