How to Sell to Walmart: A Vendor’s Complete Guide

What It’s Really Like to Sell to Walmart

Selling to Walmart is the ultimate growth milestone for consumer brands. Walmart operates over 4,700 stores in the United States alone, generates roughly $681 billion in annual revenue globally, and serves approximately 280 million customers and members each week. There is no bigger stage for a consumer product.

But Walmart is not just big—it is operationally demanding. Their EDLP (Every Day Low Price) model means razor-thin margins. Their supply chain runs on precision: OTIF (On-Time In-Full) scoring, mandatory EDI, and a chargeback program that can wipe out a quarter’s profit in a single shipment gone wrong. First-time vendors who come from D2C or Amazon often underestimate the operational leap required.

This guide covers the full journey—from getting your product in front of a Walmart buyer to surviving your first OTIF scorecard. Whether you’re targeting physical shelves or Walmart Marketplace, you’ll find the compliance details that other guides skip.

Walmart’s Vendor Programs: In-Store vs. Marketplace vs. Sam’s Club

Before applying, understand which program fits your brand. Walmart has three distinct paths for vendors, each with different fulfillment models, compliance requirements, and margin structures.

Walmart’s Private Label Brands

Walmart operates a massive private label portfolio, including Great Value (grocery), Equate (health & beauty), Mainstays (home), and Parent’s Choice (baby). These brands command significant shelf space and are priced to reinforce Walmart’s EDLP promise.

Before pitching, research whether Walmart has a private label in your category. You’ll need to demonstrate that your product drives incremental sales—not just swap revenue from their own brand. Differentiation through innovation, premium positioning, or an underserved niche is key to winning shelf space alongside Great Value.

How to Apply: Becoming a Walmart Supplier

Walmart’s supplier application process is centralized through their corporate website. The process is competitive—Walmart receives thousands of applications and only accepts a small percentage.

Step 1: Submit the Retail Supplier Application

Visit the Suppliers section on corporate.walmart.com and complete the retail supplier application. You’ll provide company details, product information, pricing, and production capacity. Walmart’s merchandising team reviews submissions and routes qualifying ones to the appropriate category buyer.

Step 2: What Walmart Looks For

Walmart buyers evaluate suppliers on five primary criteria:

• ●Price competitiveness: Can you deliver EDLP? Walmart’s entire brand promise depends on having the lowest everyday price. Your cost structure must support this without compromising quality.
• ●Scale readiness: Walmart doesn’t test with 50 stores. A regional rollout might mean 500–1,000+ locations. Can your supply chain handle that volume consistently?
• ●Proven demand: Sell-through data from other retailers, Amazon, or your D2C channel. Walmart wants evidence, not projections.
• ●Product differentiation: What makes your product worth the shelf space? Innovation, unique positioning, or an underserved category gap.
• ●Margin structure: Can you maintain viable margins at Walmart’s price points? See our wholesale pricing guide for margin benchmarks.

Step 3: Open Call & Trade Shows

Walmart hosts an annual Open Call event in Bentonville, Arkansas, where entrepreneurs pitch their products directly to Walmart buyers. Open Call is specifically designed for U.S.-made products and small businesses, and it’s one of the fastest paths to getting a buyer’s attention.

Outside of Open Call, Walmart buyers attend industry trade shows like ECRM sessions, NACS, Natural Products Expo, and category-specific expos. Having your product in front of a buyer at a trade show, combined with a formal application, can accelerate the review process.

Step 4: Broker or Rep Firms

Many successful Walmart vendors use brokers who specialize in Walmart. Companies like Acosta, Advantage Solutions, and smaller Bentonville-based firms have established buyer relationships and understand the internal merchandising process. Broker commissions typically run 3–7% of sales. For a first-time vendor without existing buyer relationships, the investment often pays for itself in faster onboarding and fewer early mistakes.

The Walmart Vendor Agreement: Key Terms to Understand

Once Walmart decides to bring your product in, you’ll negotiate and sign a vendor agreement. Walmart’s contracts are notoriously detailed and heavily favor the retailer. Here are the terms first-time vendors need to understand before signing.

Unlike smaller retailers, Walmart’s leverage means most terms are non-negotiable for small to mid-size suppliers. The key is understanding the full cost structure—deductions, allowances, OTIF penalties, and early payment discounts—before you set your wholesale price. Read our retail chargebacks guide to understand the financial impact of compliance failures.

Vendor Onboarding at Walmart

Walmart onboarding is one of the most complex in retail. There are multiple systems, portals, and data requirements to set up before you can receive your first purchase order. Plan for 60–120 days from agreement signing to first shipment.

Retail Link

Retail Link is Walmart’s proprietary vendor portal and the nerve center of your Walmart relationship. Every vendor needs Retail Link access to view sales data, manage orders, track inventory, and monitor performance metrics. Key applications within Retail Link include:

EDI Setup

Walmart requires Electronic Data Interchange (EDI) for all first-party vendor transactions. This is non-negotiable—you cannot process Walmart orders via email or a web portal. EDI automates purchase orders, invoices, and shipment notifications.

Walmart requires several EDI transaction sets including:

• ●EDI 850 — Purchase Order (incoming from Walmart)
• ●EDI 855 — Purchase Order Acknowledgment
• ●EDI 856 — Advance Shipment Notification (ASN)
• ●EDI 810 — Invoice
• ●EDI 860 — Purchase Order Change Request
• ●EDI 997 — Functional Acknowledgment
• ●EDI 824 — Application Advice (error notification for rejected documents)

Popular EDI providers for Walmart vendors include SPS Commerce, TrueCommerce, and Cleo. Expect to spend $300–$600/month for a full EDI setup. Walmart requires a testing phase against their X12 VICS standards before you go live. If Walmart rejects an EDI document (via an 824 Application Advice), you must correct and resubmit within 12 hours.

Item Setup (Item 360)

Before your product enters Walmart’s system, you must complete item setup in Item 360 with detailed product attributes including:

• ●UPC/EAN barcode registered with GS1 (GS1 Company Prefix required)
• ●Product images: High-resolution images meeting Walmart’s content standards
• ●Product descriptions: Detailed attributes including dimensions, weight, and category-specific data
• ●Case pack information: Units per case, case dimensions, pallet configuration (Ti x Hi)
• ●Compliance certifications: Category-specific (CPSIA for children’s products, FDA for food, etc.)

Walmart’s OTIF Program: The Metric That Defines Your Vendor Relationship

OTIF (On-Time In-Full) is Walmart’s most important vendor performance metric. It measures whether you deliver the right product, in the right quantity, at the right time. Poor OTIF scores lead to financial penalties and can ultimately cost you the relationship.

Walmart splits OTIF into two components, and the on-time target differs based on your delivery model:

OTIF Penalties

Walmart charges financial penalties for OTIF failures. The penalty structure applies per case for each failed metric:

• ●On-Time failure: A per-case fine is applied to the non-compliant portion of the order
• ●In-Full failure: A per-case fine is applied to the quantity shortfall
• ●Measurement window: OTIF is scored on a rolling basis, giving vendors a continuous view of performance

OTIF scores are visible in Retail Link and are a frequent topic in quarterly business reviews with your Walmart buyer. Consistently missing OTIF targets signals to Walmart that you’re an unreliable supplier, which can lead to reduced orders, shelf space cuts, or termination.

How to Hit OTIF Targets

Walmart’s Compliance Requirements

Walmart’s compliance program is one of the most demanding in retail. Every detail matters—from how you label a pallet to which carrier picks it up. Violations trigger deductions that come straight off your payment.

Routing Guide & Shipping

Walmart’s routing guide governs how you ship to their distribution centers. The system works through Walmart’s transportation management:

• ●Collect shipments: Walmart arranges and pays for transportation from your facility to their DC. You must have the shipment ready for the assigned carrier at the scheduled pickup time.
• ●Prepaid shipments: You arrange and pay for transportation. Must still meet MABD and use approved carriers.
• ●Appointment scheduling: All DC deliveries require a scheduled appointment through Walmart’s system
• ●TONU (Truck Order Not Used): If Walmart dispatches a carrier and your shipment isn’t ready, you get charged a TONU fee

ASN & Labeling Requirements

Walmart requires an EDI 856 ASN for every shipment. The ASN must be transmitted before the shipment arrives at the DC. Late or inaccurate ASNs are a leading cause of Walmart deductions.

Your shipping labels must follow Walmart’s GS1-128/SSCC-18 label format. Key labeling requirements include:

• ●GS1-128 barcode with SSCC-18 on every pallet and carton
• ●Ship-from and ship-to addresses, PO number, and carrier information
• ●Labels must match ASN data exactly—any mismatch triggers deductions
• ●4×6 inch minimum label size, placed on two adjacent sides of each pallet

Packaging & Pallet Requirements

Walmart has strict packaging requirements for DC shipments:

• ●Pallet specs: Standard GMA pallets (48″×40″), max height up to 96 inches including pallet (varies by DC and product type)
• ●Pallet configuration (Ti x Hi): Must match exactly what was set up in the item file. Deviations trigger chargebacks.
• ●Stretch wrap: All pallets must be stretch-wrapped for stability during transit
• ●Polybag suffocation warnings required on all poly-wrapped items
• ●Retail-ready packaging (PDQ/shelf-ready) where applicable

Walmart’s Chargeback & Deduction Program

Walmart’s deduction program is one of the most feared aspects of being a vendor. Deductions are financial penalties automatically deducted from your payments for compliance violations. They can be substantial—some vendors report losing 5–10% of revenue to deductions in their first year.

How to Dispute Walmart Deductions

Not all deductions are valid. Walmart provides a dispute process through the APDP (Accounts Payable Dispute Portal) and Supplier One:

• ●Review deductions weekly: Log into APDP and review all new deductions. Categorize by type.
• ●Gather documentation: BOL copies, carrier receipts, ASN transmission logs, photos, packing slips, and the Supplier Discrepancy Form.
• ●File within the dispute window: Walmart has time limits on dispute filings—missed deadlines mean the deduction stands. Expect 6–8 weeks for dispute resolution.
• ●Consider a deduction management service: Companies like SupplyPike specialize in Walmart deduction recovery.

Selling on Walmart Marketplace

Walmart Marketplace is Walmart’s third-party seller platform, open to approved U.S. businesses. Unlike the in-store vendor program (which requires Walmart to buy your product wholesale), Marketplace lets you sell directly to Walmart.com customers while keeping control of pricing and inventory.

How Walmart Marketplace Works

• ●Open application: Unlike Target Plus (invitation-only), any legitimate U.S. business can apply at marketplace.walmart.com.
• ●Referral fees: Walmart charges 6–20% per sale depending on category (most fall in 6–15%)—competitive with Amazon’s fees.
• ●No monthly subscription: Unlike Amazon’s $39.99/month professional seller fee, Walmart Marketplace has no monthly charge.
• ●Walmart Fulfillment Services (WFS): Similar to Amazon FBA—you ship inventory to Walmart warehouses and they handle fulfillment. WFS items get the “Fulfilled by Walmart” badge.
• ●API-based integration: No EDI required—Marketplace uses REST APIs for inventory, orders, and catalog management.

When Marketplace Makes Sense

Walmart Marketplace is a strong entry point for brands that want to test Walmart demand without the full operational complexity of in-store vendor compliance. It’s particularly appealing for:

• ●D2C brands already proficient at e-commerce fulfillment
• ●Amazon sellers wanting to diversify their marketplace presence
• ●Brands wanting to build Walmart sales data before pitching for in-store placement
• ●Companies that can’t yet meet the production volume for 4,700+ stores
