Walmart Marketplace Seller Launch Checklist
This is a practical, non-exhaustive checklist for sellers preparing to apply to Walmart Marketplace or getting ready to launch their first listings. It reflects the requirements and common friction points covered across the guides on SellerScale Lab — it doesn’t replace reading Walmart’s own seller policies, which can change.
1. Business & legal setup
- A registered U.S. business entity (sole proprietorship, LLC, or corporation) with an EIN — Walmart's application asks for business identification, not just a personal name.
- A business bank account separate from personal finances, since Walmart pays out to a business account.
- Your business address and contact details ready to enter exactly as they appear on your registration documents — mismatches between what you enter and what's on file are a common cause of verification delays.
- Any category-specific licenses your products require (e.g. certain supplements, electronics, or regulated goods) gathered before you apply, not after.
2. Product & catalog readiness
- Valid GTINs/UPCs for every product you plan to list — Walmart's catalog matches listings to existing product records using these.
- Clear, accurate product titles, descriptions, and specifications written for your actual product, not copied wholesale from a competitor's listing.
- At least one clean, well-lit primary product image per listing that meets Walmart's image requirements (white background, no watermarks or promotional text).
- A read-through of Walmart's prohibited and restricted products policy for your category, so you're not blocked after investing time in listings.
3. Fulfillment decision
- A decision on fulfillment method — Walmart Fulfillment Services (WFS) vs. seller-fulfilled — made before you price products, since the cost structures differ.
- If seller-fulfilled: a realistic plan for shipping speed and carrier costs, since fulfillment speed affects your search visibility on Walmart.
- If WFS: your product dimensions and weights on hand, since those drive the fulfillment fee estimate (the WFS Profit Calculator on this site uses exactly these inputs).
4. Account health basics
- A plan for who monitors your Walmart Seller Center dashboard regularly — order defect rate, on-time shipping, and cancellation rate all affect account standing.
- A return address and return policy that's actually accurate for how you plan to operate, since return handling is part of account health.
- A basic customer service response plan — Walmart expects timely responses to buyer messages.
5. First 30 days
- Start with a small, focused set of listings rather than uploading your entire catalog at once — it's easier to catch data or compliance issues early.
- Track your Buy Box win rate and listing quality score from day one so you notice problems while they're still small.
- Revisit pricing and margins after your first few sales using real fee data, not just estimates.
