Walmart Marketplace-specific onboarding context
- Walmart Marketplace and Seller Center workflows differ from store-supplier RetailLink EDI — we help marketplace sellers add structured X12 when programs require it alongside portal operations.
- Walmart Marketplace EDI onboarding window: 4–10 weeks. Marketplace onboarding timelines vary by item setup and test waves. Do not assume RetailLink supplier timelines apply — confirm your program lane (marketplace vs store supplier) before scoping documents.
- Walmart Marketplace EDI document checklist includes 850 / 855 — purchase orders and acknowledgments for marketplace or wholesale lanes; 856 — ASN with item and carton detail when routing requires structured ship notices; 810 — invoice timing aligned to PO and receipt references.
- Separate marketplace guidance from RetailLink store-supplier flows — fewer wrong-document surprises.
