Walmart seller glossary
WFS (Walmart Fulfillment Services)
Walmart's first-party fulfillment program — analogous to Amazon's FBA. Ship inventory to Walmart's warehouses; they pick, pack, and ship to buyers.
Benefits: Walmart-branded packaging, 2-day delivery eligibility, meaningful Buy-Box weighting boost, eligibility for Walmart+ filters.
Most categories see a 15-25% conversion-rate lift moving from seller-fulfilled to WFS. The Buy Box advantage often offsets the fee delta on its own.
