How to Become a Walmart Supplier

Walmart is the largest retailer in the world, with more than 4,600 U.S. stores and a supply chain that moves billions of units annually. Becoming a Walmart supplier is one of the most significant growth opportunities available to a product brand — but the path from initial inquiry to first purchase order is structured, deliberate, and compliance-heavy. This guide walks through each step of the Walmart supplier onboarding process so you know what to expect and how to prepare.

1. Determine If You're Ready

Before applying, honestly assess your operational readiness. Walmart expects suppliers to be fully set up for compliance from day one — there is no grace period for getting EDI connected, labeling right, or OTIF performance up to threshold.

• Production capacity: Can you reliably fulfill large, recurring purchase orders at Walmart's volume and velocity?
• EDI capability: Do you have EDI 850/856/810 connectivity established or a provider ready to implement it?
• GS1 registration: Do you have a GS1 Company Prefix and valid GTINs for all products?
• Insurance: Do you carry the product liability insurance levels Walmart requires (typically $2M+ per occurrence)?
• Regulatory compliance: Are your products compliant with all applicable federal and state regulations, labeling laws, and safety standards?

2. Submit Your Application via Walmart Supplier Center

All new supplier applications are submitted through Walmart Supplier Center (suppliercenter.walmart.com). This is the primary hub for all supplier activity at Walmart — from initial application through ongoing compliance management.

• Create a Supplier Center account and complete the new supplier registration form
• Provide company information, product categories, and a product overview
• Upload supporting documentation: business registration, insurance certificates, product certifications, and any applicable regulatory approvals
• Walmart buyers review applications based on product category fit, pricing competitiveness, and supplier capability
• If your application advances, a Walmart buyer or sourcing manager will reach out to schedule an initial review

3. Buyer Meeting & Product Review

If Walmart is interested in your products, you'll be invited to a buyer meeting — either in person at Walmart's Bentonville, AR headquarters or virtually. This is your opportunity to present your product, pricing, and business case.

• Product samples: Bring or ship samples in advance — buyers evaluate product quality, packaging, and retail-readiness firsthand
• Pricing: Be prepared to discuss cost, retail price, margin, and how your pricing compares to existing items on the shelf
• Packaging compliance: Your retail packaging must meet Walmart's standards — labeling, barcode placement, and shelf-ready presentation matter
• Sustainability: Walmart's Project Gigaton sustainability initiative is increasingly part of supplier conversations — be prepared to discuss your environmental practices
• Supply chain capability: Buyers will ask about your production lead times, minimum order quantities, and ability to scale

4. Complete Supplier Onboarding

If Walmart decides to move forward, you'll enter formal onboarding through Supplier Center. This involves completing a series of setup tasks before any purchase orders are issued.

• Supplier agreement: Review and execute Walmart's Supplier Agreement — understand payment terms, compliance obligations, and chargeback policies before signing
• Insurance verification: Submit certificates of insurance meeting Walmart's requirements
• EDI setup: Establish EDI connectivity for 850, 856, and 810 transaction sets through Walmart's approved EDI network. Test all transaction sets before going live
• Item setup: Create item listings in Walmart's item management system — product attributes, GTINs, images, and descriptions must be complete and accurate
• Retail Link access: Get trained on Retail Link, Walmart's supplier data portal — this is where you'll monitor OTIF scores, sales data, and compliance performance going forward

5. Understand Walmart's Compliance Programs

Before your first PO ships, your operations team needs to fully understand and be set up for Walmart's core compliance programs. Non-compliance chargebacks start accumulating from shipment one.

• OTIF (On-Time In-Full): Walmart's primary supply chain performance program. Must Arrive By Date (MABD) compliance is required — penalties up to 3% of COGS for late or short shipments
• SQEP (Supplier Quality Excellence Program): Measures ASN accuracy and physical barcode quality. $0.75 per defective unit for barcode failures
• Routing guide compliance: Use only Walmart-approved carriers for Collect shipments. Unauthorized carrier use triggers routing chargebacks
• GS1-128 labeling: All cartons must have GS1-128 compliant labels with correct retailer-specific data fields before shipment

6. Ship Your First Purchase Order

When your first PO arrives in EDI, follow this sequence carefully:

• Acknowledge the EDI 850 (Purchase Order) within Walmart's required window
• Confirm inventory availability and production readiness for the full PO quantity
• Generate GS1-128 compliant carton labels per Walmart's specification
• Book freight with a Walmart-approved carrier (Collect shipments) or arrange prepaid transportation within the delivery window
• Transmit the EDI 856 (ASN) before the shipment departs — not after it arrives at the DC
• Submit the EDI 810 (Invoice) per Walmart's invoicing schedule
• Monitor your Retail Link OTIF scorecard the following week to verify the shipment was received compliantly
