How do I sell on Walmart Marketplace from my Shopify store?

What you need before you connect

Walmart Marketplace is Walmart's online marketplace where outside sellers list products next to Walmart's own. You cannot just switch it on from Shopify. You need a verified seller account, and you need to be approved to sell. Shopify's help center says the same for every marketplace: have a verified seller's account and approval first, then connect.

Shopify's checklist for its own connector also includes:

• A Shopify online store that is not set to private access.
• A valid payment provider turned on in your admin.
• Shipping rates set for the places you sell, and prices in a currency that place supports.
• Your store policies visible on the marketplace, as that marketplace requires.
• A payment method on the marketplace and the bank account where you want to be paid. When a Walmart order comes in, Walmart pays you, not Shopify.
• Walmart shipping settings. Shopify points to Walmart's shipping template tools in Seller Center, Walmart's seller dashboard, either automated or manual.

Walmart's own getting-started page lists the minimum qualifications to join, as of November 2026:

• A business tax ID (a personal Social Security number is not accepted) or a business license number.
• Documents that verify your business name and address.
• A history of marketplace or ecommerce success.
• Products with GTINs or UPCs (barcode numbers) from a GS1 company prefix.
• An account with Marketplace Wallet, Walmart's payment service, or a third-party payment provider.
• A catalog that follows Walmart's Prohibited Products Policy.
• Fulfillment through Walmart Fulfillment Services or another US warehouse that can handle returns and meet Walmart's Seller Performance Standards.

Once approved, you manage your account, reports and catalog in Seller Center, and you load products through a solution provider, Walmart's API, or Seller Center itself using Setup by Match, Single Item or Bulk Upload. Walmart's onboarding guide covers the step-by-step detail, and these rules change, so read the page before you apply.

What Walmart charges

As of November 2026, Walmart says sellers pay no monthly or set-up fees. You pay a referral fee, a percentage of each sale, set by product category. A few examples from Walmart's pricing page:

Category	Referral fee
Consumer electronics	8%
Books	15%
Baby products	8% on items $10 or less, 15% above $10
Apparel and accessories	5% up to $15, 10% from $15 to $20, 15% above $20

Walmart also offers Walmart Fulfillment Services (WFS), a program where Walmart stores and ships your goods, with fees listed separately. Look at the full table for your category before you price anything. A 15% referral fee on a thin-margin item can erase your profit. See Amazon seller profit margin for the same sums on Amazon.

Connector options and what they cost

Option	What it is	Cost as of November 2026
Shopify Marketplace Connect	Shopify's own app (formerly Codisto). Connects Amazon, Target Plus, Walmart (US only) and eBay.	Free to install. First 50 synced marketplace orders a month free, then 1% per extra synced order, capped at $99 a month.
Walmart Integration by GeekSeller	An app that connects Shopify to the Walmart US marketplace and syncs products, stock and orders. Supports WFS and Walmart's multichannel fulfillment.	Two plans with a 7-day free trial. The listing shows prices in rupees, so check the listing for the current price in your currency.

Many other apps exist. Judge any of them on the same four points: does it sync stock both ways, does it import orders and send tracking back, does it handle variants (size and colour options), and how fast does support answer.

One rule from Shopify matters a lot: connect only one marketplace connector app at a time. Two apps writing to the same listings is how stock numbers get overwritten. If you switch, disconnect and uninstall the old app first.

Set-up steps with Shopify Marketplace Connect

1. Get your Walmart seller account verified and approved.
2. In Shopify, install the Marketplace Connect app and check your store meets the requirements above.
3. Go to Apps, then Marketplace Connect, and click Connect account next to Walmart. Follow the sign-in prompts.
4. Set where Walmart stock should come from. Marketplace Connect lets you choose the inventory location used for your listings, so decide this on purpose.
5. Create listings. Use single edit for a few products, bulk edit for a whole catalog, and attribute mapping to control how your product fields appear on Walmart. If you already have Walmart listings, link them to your Shopify products instead of creating duplicates.
6. Place a test order if you can, and check it appears in Shopify with Walmart in the Channel field.
7. Fulfil it. Marketplace Connect sends shipping status and tracking back to Walmart after you fulfil.

With another app, the steps are similar: connect the account, map products, choose the stock source, and test an order.

Common sync problems

Most Walmart sync trouble comes from a few causes. These are common patterns across channels:

• Missing product data. Walmart wants complete listing details, and a product that fails its rules is rejected or held. Fix the field in Shopify, then resubmit.
• Duplicate listings. You listed by hand on Walmart and then synced from Shopify. Link the existing listing to the Shopify product.
• Stock does not match. Two apps are connected, or the wrong Shopify location feeds Walmart. Also check whether the product is active at that location, since a dash under Available means it is not sellable there.
• Overselling. Even a fast sync leaves a gap between a sale on one channel and the stock update on the other. Hold a small buffer of stock back (use the Unavailable state in Shopify).
• Tracking not sent. The order was marked fulfilled in a different way than the connector expects. Fulfil from the imported order in Shopify.
• Price differences. Walmart fees are higher than your store's costs, so one price for both can lose money. Set a channel price.

The same causes show up on other channels, so the fixes in Shopify and Amazon sync problems apply here too.

Can it be automated further?

The connector already automates the core loop: listings, orders, stock and tracking. What it does not do is the work around it. Examples:

• A daily check that Shopify and Walmart stock still agree, with an alert if not.
• Pausing a listing when stock falls below a floor.
• Logging each channel's sales and fees into one report.

Shopify Flow can handle the Shopify-side parts, as I explain in the Shopify Flow guide. For jobs that cross several systems, look at business process automation. Once Walmart is your third or fourth channel, multichannel inventory management software is worth a look, because stock is the first thing to break.

How I'd approach this

I would start small. Pick 20 to 50 of your best products with full data and healthy margins after Walmart's fee. Use Shopify's own Marketplace Connect if you are in the US and under 50 Walmart orders a month, because it costs nothing at that size and it is one fewer vendor.

Set a stock buffer, set a Walmart price that covers the referral fee, and check the first ten orders by hand. Only then widen the catalog. When Walmart and other channels together start costing you hours a week in fixes, that is the sign to automate the checks or build something that watches stock for you. I can map that with you on a short call.
