Walmart Marketplace is the closest thing US ecommerce has to an early-Amazon moment: the second-largest retail audience in the country, with a fraction of Amazon’s seller competition. More than 200,000 active sellers compete for Walmart.com’s traffic — Amazon has several million. If you already run a store or sell on other marketplaces, learning how to sell on Walmart is mostly a matter of clearing the approval bar, getting your product data in shape, and understanding one pricing rule that catches almost every new seller off guard. This guide walks through the whole process: requirements, real fees, setup, fulfillment options, and the pricing mechanics that decide who wins the Buy Box.

What is Walmart Marketplace
Walmart Marketplace is the third-party seller program on Walmart.com. Your products appear next to Walmart’s own inventory, you keep control of pricing and fulfillment, and Walmart takes a referral fee on each sale. Walmart pitches its US audience at well over 100 million unique monthly visitors, and — unlike a new webshop — those shoppers arrive with a card in hand.
The practical differences from Amazon matter more than the similarities:
The approval gate is the point. Walmart curates supply, which is why categories that are brutally saturated on Amazon can still be winnable on Walmart. It also inherits Walmart’s retail DNA: the whole platform is built around its everyday-low-price culture, and that shapes the pricing rules you’ll read about below.
Requirements: who gets approved
Walmart wants sellers with a track record, not first-timers. Before you apply, make sure you can show:
- A registered business — a US Business Tax ID (EIN; a personal SSN doesn’t qualify) or a legal entity in one of the approved international countries.
- Marketplace or DTC history — Walmart explicitly asks about your ecommerce experience and prior marketplace performance. Strong metrics on Amazon or eBay are your best argument.
- GS1-issued product identifiers — every listing needs a legitimate UPC/GTIN. Recycled or third-party barcodes are a common rejection reason.
- Fulfillment capability — reliable US fulfillment with fast shipping, either your own operation, a 3PL, or Walmart Fulfillment Services.
- A catalog that fits — products must comply with Walmart’s prohibited-items policy, and niches with proven demand get approved faster.
Approval typically takes two to four weeks. Incomplete business documents and mismatched company details are the most common reasons applications stall, so have your EIN letter, bank details, and product information ready before you start.
How much it costs to sell on Walmart
There’s no subscription and no listing fee — you pay when you sell. The referral fee depends on category, and for most of the catalog it’s 15%:
Run the margin math before you onboard a catalog, not after. A product with a 25% gross margin loses most of it to a 15% referral fee plus shipping; the SKUs that thrive on Walmart tend to be the ones where you hold a genuine cost advantage. If you use Walmart Fulfillment Services, add its weight-based fulfillment and storage fees to the model — more on that below.
How to sell on Walmart Marketplace, step by step
The end-to-end process, from application to first sale:
- Apply at marketplace.walmart.com. You’ll need your business details, EIN, and a summary of your ecommerce track record. Be specific about categories, catalog size, and where you sell today.
- Wait for approval (typically 2–4 weeks). Respond quickly if Walmart asks for extra verification — stalled threads are where applications go to die.
- Complete onboarding in Seller Center. Walmart Seller Center is the dashboard where everything happens: company profile, bank account for payouts, shipping templates, and tax settings.
- Upload your catalog. Small catalogs can be listed one by one; anything serious goes in via bulk feed, API, or an integration from your platform — Shopify, WooCommerce, Magento and BigCommerce all connect. This is where clean product data pays off.
- Set your shipping. Fast, free shipping is table stakes on Walmart; listings with two-day delivery tags convert measurably better and rank higher in search.
- Price your items and launch. Check every price against Walmart’s parity rules first (see the pricing section — this is the step most new sellers get wrong).
- Trigger the launch checklist. Walmart reviews a test order flow before your items go live. After that, you’re selling.
Listing products: feeds, GTINs, and content quality
Walmart’s search algorithm leans heavily on listing quality — it even scores you on it. Three things decide whether your products get found:
Identifiers. Every item needs a GS1-legitimate UPC or GTIN, and Walmart validates them. If your identifier data is messy — missing GTINs, wrong MPNs, duplicated barcodes — fix that before onboarding; our guide to product identifiers (GTIN, UPC, EAN, MPN) covers what each code is and how to get real ones.
Feed quality. Walmart is stricter than most channels about attributes: shelf categorization, size and color as structured fields, shipping weights. Listings with thin attributes quietly lose search placement. If you manage more than a handful of SKUs, run the catalog through a proper product feed management workflow so every channel gets the attributes it expects — the same source feed can then serve Walmart, Google Shopping, and the 1,500+ other channel templates without re-entering data.
Content score. Walmart’s Listing Quality dashboard grades titles, images, and attributes per SKU. Aim for titles in Walmart’s preferred format (brand + product + key attributes), at least four images, and complete specs. It’s unglamorous work that directly moves rank.
WFS vs seller fulfillment
You have two realistic options: fulfill orders yourself (or via your 3PL), or hand logistics to Walmart Fulfillment Services — Walmart’s equivalent of FBA.
The honest tradeoff: WFS buys you conversion (fast delivery tags) at the price of fee stacking. On low-priced items, referral fee + WFS fees + storage can eat the entire margin — model it per SKU, not per catalog.
Pricing on Walmart: parity rules and the Buy Box
This is the section that saves you a delisting. Walmart enforces its low-price positioning with two automated rules every seller must know:
The Price Parity Rule. If Walmart’s systems find the same item from the same seller cheaper on a competing site (including shipping), the listing is unpublished automatically. In practice that means you can’t treat Walmart as the place where you quietly run higher prices. Walmart built its brand on everyday low prices, and the marketplace inherits that culture by force.
The Reasonable Price rule. Separately, if your total offer price (item plus shipping) sits far outside the range Walmart considers reasonable against its market reference data — any seller, not just you — the item is unpublished with the “Reasonable Price Not Satisfied” reason code. Fix the price and listings typically republish within about 48 hours.
The Buy Box. When multiple sellers list the same item, Walmart awards the default “Add to cart” to one of them — price is the dominant factor, weighted by shipping speed and seller performance. Winning it isn’t about being cheap once; it’s about reacting when a competitor moves. That’s a job for software: a dynamic repricing setup that watches competing offers and adjusts within the floor you set protects both the Buy Box and your margin — and because it also tracks your own prices across channels, it keeps you clear of parity flags before Walmart notices them.
Two practical rules from experience: set a hard price floor per SKU before you automate anything, and monitor your own multichannel spread weekly — most parity violations aren’t strategy, they’re a forgotten promo still running on your webshop.
Is selling on Walmart worth it?
For established sellers, usually yes — with the right expectations. The upside is real: enormous audience, thinner competition, no monthly fee, and a search algorithm that still rewards well-built listings over ad spend. The constraints are just as real: approval takes effort, margins must survive 15% plus fulfillment, and the parity rules limit how you price across channels.
The sellers who do best treat Walmart as one channel in a portfolio rather than a silver bullet — the same catalog and feed infrastructure that runs Walmart also runs eBay, Google Shopping, and the rest. Diversified sellers also feel parity rules less: when your pricing is coherent everywhere, Walmart’s enforcement never triggers.
Frequently asked questions
How much does it cost to sell on Walmart Marketplace?
There’s no monthly subscription or listing fee. You pay a referral fee per sale — 15% in most categories, 8% for consumer electronics, 6% for personal computers, and up to 20% on the first $250 for jewelry. WFS fulfillment and storage fees are extra if you use them.
How long does Walmart Marketplace approval take?
Typically two to four weeks. Complete business documentation (EIN, bank details) and a demonstrable marketplace track record speed it up; unanswered verification emails are the most common cause of delays.
Can I sell on Walmart with Shopify?
Yes. Walmart integrates with Shopify (and WooCommerce, Magento, BigCommerce) so your catalog, inventory, and orders sync automatically. You still need to be approved as a Walmart seller first.
Do I need a UPC to sell on Walmart?
Yes — every listing requires a GS1-legitimate UPC/GTIN, and Walmart validates them. Barcodes bought from third-party resellers are a frequent cause of listing rejections.
