Walmart Retail Link Readiness: A Checklist Before You Get a Vendor Offer
Walmart Retail Link readiness is less about the portal than about what sits behind it. Retail Link is where Walmart suppliers work: Walmart's own onboarding checklist has you upload insurance and manage quotes there, and says full access arrives once you finish onboarding and set up at least one item. By that point your data connections, shipping process and compliance owner need to already work.
This post is a practical checklist for brands heading toward a Walmart vendor relationship, whether through a buyer conversation or by growing out of Marketplace. Our guide to getting into Walmart retail covers the earlier steps.
EDI and OMS requirements before you can support a vendor relationship
What Walmart says. Walmart's supplier onboarding checklist (opens in new tab) includes a step to set up and test EDI. It says EDI is needed if any banner other than Walmart.com is selected, WebEDI is needed if Walmart.com is the only banner, and AS2 is required for GNFR or pharmacy products or for more than 15,000 documents a year. The supplier's own GS1 company prefix is also requested on application documents, per Walmart's supplier requirements (opens in new tab).
Which EDI documents you exchange depends on the program. For drop-ship vendors, Walmart's developer portal (opens in new tab) lists the purchase order (850), purchase order acknowledgement (855), ship notice (856), inventory (846), purchase order change (860), unit cost (879), application advice (824) and functional acknowledgement (997).
What Walmart doesn't say. Its public pages don't tell you which order management system you need, or how long EDI testing takes. That part is on you.
What we see: Spreadsheets don't talk to EDI. If orders and inventory are still managed by hand, close that gap before testing starts. Small brands can get there without a full ERP, but you need something an EDI provider can connect to, such as an ERP, your 3PL's warehouse system or a lighter integration. Plan for weeks of mapping and testing, and build one source of truth for item data, including case and pallet dimensions, before item setup begins. That is the systems side of Walmart Retail Link readiness.
Routing guide and ASN/BOL basics you'll need to have solved
What Walmart says. Its supplier requirements page (opens in new tab) says Walmart's supply chain depends on suppliers packing, labeling and shipping to specification, covering case packaging, labeling, palletizing and trailer loading, and points to a supply chain packaging guide. The onboarding checklist adds that suppliers who ship collect set up ship points in the Transportation Supply Chain Portal after onboarding.
What Walmart doesn't say publicly. We didn't find Walmart's inbound routing guide, or its ASN and bill of lading rules for supplier freight, on its public pages. Treat the guide you receive as your account is set up as the source of truth, and read it before you quote a ship date.
What to have solved first: Most Walmart Retail Link readiness gaps we see sit in these five places, where first shipments tend to go wrong in the retail launches we support:
- Who books freight and how. Know whether you ship collect or prepaid, which carriers are approved, and who in your team or your 3PL's team makes the booking.
- Labels validated before the first order. Carton and pallet labels need the right data in the right positions. Test the template instead of finding out at the dock.
- An ASN that matches the physical shipment. Carton counts, PO numbers and carrier details have to agree with what was packed. A mismatch usually shows up as a receiving discrepancy, and the financial cleanup can take weeks.
- A test shipment before a live order. If the timeline allows it, run one. One prevented first-shipment problem is worth the cost.
- A named person for routing updates. Assign one reader for guide updates and have your 3PL working from the same version.
What chargebacks look like on the vendor side, and how to avoid the first one
What's been reported. The clearest public signal is Walmart's on-time, in-full (OTIF) program. Supply Chain Dive (opens in new tab) reported in 2019 that Walmart raised its requirement to 87%, with a fine of 3% of the cost of goods for suppliers who miss it, per a Walmart spokesperson. Talk Business & Politics (opens in new tab) reported a September 2020 Walmart memo raising the requirement to 98%, effective Sept. 15, 2020, with the same 3% fine.
What Walmart's pages say. Its Standards for Suppliers (opens in new tab) say violations may bring consequences up to and including termination of business, but describe no fines or deductions. The onboarding checklist asks drop-ship vendors for a finance contact for auto chargebacks and says accepting the supplier agreements "is not a guarantee of business."
How to avoid the first one:
- Read the agreement before you sign it. Compliance penalties and markdown terms can sit in there, and they are easier to question before signing than after the first deduction.
- Run a pre-shipment checklist on every order. Labels, counts, carrier and ship window, checked by someone other than the person who packed it.
- Keep proof. Hold the bill of lading, proof of delivery and label photos. In our retail work, deductions often arrive as a short payment, and documentation is what makes a dispute winnable.
- Tell disputable from avoidable. A claim you can disprove with documents is worth fighting. A real miss, such as a late shipment, usually isn't.
- Assign someone to watch deductions. If it's nobody, you find out when the payment comes in short.
The 3PL maturity bar for retail-grade compliance
Walmart's public pages don't set a standard for third-party logistics providers. Its supplier requirements page (opens in new tab) does say the supply chain depends on suppliers packing, labeling and shipping to specification. In practice, that means your 3PL's mistakes land on your account.
| Capability | DTC-grade 3PL | Retail-grade 3PL |
|---|---|---|
| Labels | Shipping labels for parcel | Carton and pallet labels to a retailer's spec, validated before the first order |
| Data exchange | Order feeds from a storefront | Works with your EDI provider and sends ASNs that match what was packed |
| Routing | Books its preferred carriers | Follows the retailer's routing guide and appointment process |
| Documents | Parcel tracking | Accurate bill of lading with counts, weights and dimensions |
| Process | General procedures | A written procedure for your retail shipments, so knowledge survives staff changes |
| Inventory | Separate stock for DTC | Ideally one inventory pool that serves both DTC and retail |
A few rules we apply. Ask for experience in your product category, not just "we ship to retailers", and ask for references. Don't be the first retail shipment your 3PL has ever done. If your current provider is strong at DTC but new to retail, moving before launch often costs less than teaching them on a live order. If it truly can't be avoided, stretch the timeline and run a test shipment first.
A Walmart Retail Link readiness self-assessment checklist
Use this list to gauge your Walmart Retail Link readiness. Tick what is true today, not what you plan to finish.
The three that matter most
[ ] A 3PL with real retail compliance experience in your category, or a plan to move before launch
[ ] An order and inventory system an EDI provider can connect to
[ ] A named person who owns compliance, routing updates and deductions
Company and item setup
[ ] GS1 company prefix membership number in hand (Walmart)
[ ] Federal Tax ID, D&B number and a US bank account ready (Walmart)
[ ] Insurance certificate listing Walmart as additional insured and certificate holder, ready to upload in Retail Link within 30 days of accepting the Supplier Agreement (Walmart)
[ ] One source of truth for item data, including case and pallet dimensions
[ ] Supplier agreement read closely, including compliance penalties and markdown terms
Systems and shipping
[ ] EDI type decided: EDI, WebEDI or AS2, based on the banners you'll sell to and your document volume (Walmart)
[ ] The documents your program needs mapped and tested with your EDI provider
[ ] Carton and pallet labels validated before the first order
[ ] Freight terms decided and carriers and appointment process understood
[ ] A written procedure for your retail shipments that your 3PL follows
[ ] A test shipment completed before the first live order
Money and demand
[ ] Cash to cover the gap between paying your 3PL and getting paid
[ ] A finance contact watching deductions and OTIF results
[ ] Proven sales velocity in another channel, such as Walmart Marketplace
Any box unticked in the first group is worth fixing before you push for a purchase order.
