Walmart runs two very different supplier relationships under the word "integration," and mixing them up is the fastest way to build the wrong connection. Walmart Marketplace is a third-party relationship: you list your own products under your own name and sell directly to the customer. Walmart DSV is a first-party, wholesale relationship: Walmart buys from you and resells under its own name, and your system talks to Walmart's Supplier Center instead of a marketplace API. This guide covers both, how to tell which one applies to you, and what changes technically once you know.

Which Walmart Program Are You Actually In?
Two questions settle it. First: whose name is on the listing? If your brand shows as the seller, you're on Marketplace. If the item is listed as "Sold by Walmart" or "Fulfilled by Walmart," you're a DSV. Second: how did you apply? Marketplace is open self-service signup. DSV is invite-only or requires a direct application through Walmart's supplier onboarding, and it's aimed at established, high-volume suppliers rather than new sellers.
A business can run both at once for different products, and the two are configured completely differently inside InfiPlex, so knowing which one applies to which of your items matters before you connect anything.
Walmart Marketplace vs Walmart DSV, Side by Side
| Walmart Marketplace | Walmart DSV | |
|---|---|---|
| Seller of record | You. Your brand name shows on the listing | Walmart. Listed as "Sold by Walmart" |
| Pricing | You set it, subject to Walmart's price and Buy Box rules | Walmart sets the retail price; you're paid an agreed wholesale cost |
| How orders arrive | Through the Walmart Marketplace API, synced roughly every 15 minutes | Through Walmart's Supplier Center, one purchase order per consumer order |
| Shipping cost | Yours to cover, or a per-unit fee if you use Walmart Fulfillment Services | Walmart's. A prepaid shipping label comes with the order |
| Delivery options | Ship to the customer's address only | Ship to the customer, or to a Walmart store for pickup using a Site-to-Store label |
| Acknowledgment window | Not applicable in the same sense; the API confirms receipt automatically | An EDI 855 due within hours, tighter than standard EDI retailer windows |
| Inventory reporting | You update it through the API whenever your stock changes | An EDI 846 feed required at least once daily per warehouse, more often for fast movers |
| How you apply | Open, self-service signup | Invite-only or direct application, aimed at established high-volume suppliers |
What EDI Documents Does Walmart DSV Require?
DSV runs on the same core EDI set Walmart uses for its store suppliers, plus two documents that behave more strictly in DSV specifically.
| Document | What it does |
|---|---|
| 850 Purchase Order | One arrives per consumer order, so your daily order volume is your daily 850 volume. |
| 855 PO Acknowledgment | Confirms you can fill the order. DSV's window is measured in hours, not the 24-hour window standard EDI trading partners typically get. |
| 856 Advance Ship Notice | Sent before the shipment arrives, describing exactly what's in it. The most chargeback-prone document in the set if it doesn't match the physical shipment. |
| 810 Invoice | Bills Walmart for what shipped, reconciled against the 850 and 856. |
| 846 Inventory Inquiry/Advice | DSV-specific. Reports available stock at least once a business day per warehouse, more often for high-velocity SKUs, since Walmart's system won't route an order to you without a current count. |
Marketplace sellers don't run this document set at all under normal circumstances. The exception: large-volume Marketplace sellers who fulfill through Walmart Fulfillment Services can pick up EDI-style requirements similar to a store supplier, which is a separate case from the standard self-fulfilled Marketplace seller this article is written for.
Is Walmart Fulfillment Services a Third Program?
No, and this is where a lot of confusion starts. Walmart Fulfillment Services, WFS, is a fulfillment choice available to Marketplace sellers, not a separate order-flow program. It works the way Amazon's FBA does: you send inventory to a Walmart fulfillment center, and Walmart picks, packs, and ships it. The order still arrives through the Marketplace API exactly as it would if you shipped it yourself. WFS changes who fulfills the order, not which integration path you're on.
How Does InfiPlex Handle Walmart Integration?
InfiPlex runs both programs, and because they work so differently, each connects to InfiPlex on its own terms rather than being forced through one shared setup.
For Marketplace, InfiPlex pulls new orders roughly every 15 minutes, acknowledges them automatically, and lets you ship with over 100 built-in carrier options, route to a warehouse or 3PL, or push the order into your ERP. The moment a label is purchased, tracking and updated inventory counts flow back to Walmart automatically.
For DSV, InfiPlex pulls orders from Walmart's Supplier Center, supports both a standard carrier label and a Site-to-Store label for store pickup, and sends tracking and inventory back the same way, with the underlying EDI documents, including the 846 feed, generated and transmitted without anyone typing them by hand.
Orders from either program sit alongside every other channel you sell on in one inventory pool. Pricing starts at $49.99 a month and is published in full, support is USA based, and a Walmart program you haven't connected yet gets built at no additional cost on Growth plans.

Walmart Marketplace vs DSV Questions
What is the difference between Walmart Marketplace and Walmart DSV?
Marketplace is a third-party relationship: you list under your own brand and sell directly to the customer. DSV is a first-party wholesale relationship: Walmart buys your product and resells it under its own name, and you ship on Walmart's behalf using a prepaid label.
How do I know if I'm a Marketplace seller or a DSV?
Check the listing. If your brand shows as the seller, you're on Marketplace. If it says "Sold by Walmart" or "Fulfilled by Walmart," you're a DSV. DSV is also invite-only or direct-application, unlike Marketplace's open signup.
Does Walmart DSV require EDI?
Yes. DSV runs the standard 850, 855, 856, and 810 set, plus an 846 inventory feed specific to DSV. The 855 acknowledgment window is measured in hours rather than the 24-hour window typical EDI retail trading partners allow.
Is Walmart Fulfillment Services a separate integration from Marketplace?
No. WFS is a fulfillment choice within the Marketplace program, similar to Amazon FBA. Orders still arrive through the same Marketplace API regardless of whether you or WFS ships them.
Can I be both a Walmart Marketplace seller and a DSV at the same time?
Yes, for different products. The two programs are configured separately, so which items are on which program needs to be tracked, since the order flow and documents differ completely between them.
Does Walmart DSV support store pickup?
Yes. DSV orders can ship to the customer's address or to a Walmart store for pickup using a Site-to-Store label. This option is not available to standard Marketplace sellers.
