Configuring your shipping settings correctly matters more than it looks — Walmart tracks shipping performance closely, and getting it wrong can suppress your listings before you've made a single sale.
Set up your shipping templates in Seller Center, choosing which of Walmart's shipping-speed tiers you can realistically meet: Value (6–7 days), Standard (3–5 days), TwoDay (2 days), or OneDay (1 day) — commit only to speeds your fulfillment process can actually hit, since missed delivery windows hurt your performance metrics.
If you're self-fulfilling, ship only with an approved carrier. Walmart's preferred carriers are USPS, FedEx, and UPS, and its approved-carrier list runs to more than 50 names worldwide. Shipping through a non-approved carrier isn't just discouraged — Walmart's own guidance states it 'may result in suppression, suspension or termination' of your account. Whichever carrier you use, you're required to provide valid tracking information on more than 99% of your Marketplace orders under Walmart's Seller Performance Standards, so pick a shipping method that generates trackable labels automatically rather than relying on manual entry.
Finally, agree to Walmart's returns service and set up a return center to handle return shipping labels and customer inquiries. Properly configured shipping and returns settings protect your performance metrics as much as they protect the customer experience.
