Walmart's free app for running your Marketplace store, what it can't do, and the app you need for choosing products.
Updated October 27, 2026 · By the Margenos team
Yes, Walmart has an official Walmart Seller app. It's free on iPhone and Android, and it lets approved U.S. Walmart Marketplace sellers run their store from a phone: ship orders, update prices and inventory, answer customers and check sales. It is a store-management app. It doesn't tell you which products are worth buying to sell, which is a different kind of app. This page covers what the Walmart Seller app does, how to download it, and where a product research tool like Margenos fits.
According to Walmart's Marketplace pages, the app covers most day-to-day store tasks:
The iPhone version needs iOS 16 or later. Walmart's help guide also says Android users can install the app's .apk file directly if they can't use Google Play.
| App | Who it's for | What it does |
|---|---|---|
| Walmart Seller app | Approved Marketplace sellers | Runs your store: orders, items, WFS, messages, sales |
| Walmart App Store (in Seller Center) | Sellers who want integrations | A directory of third-party apps, such as shipping and inventory tools, that connect to your account |
| Walmart shopping app | Shoppers | Buying on Walmart.com, with a barcode scanner for price checks in stores |
If you came here looking for the shopper's barcode scanner, that's in the regular Walmart app. Resellers who want to scan a barcode and see profit should read about the Walmart scanner app instead.
Most sellers end up using two kinds of apps: one to run the store and one to decide what to stock. They answer different questions.

| Needs a seller account | Yes | No |
| Fees, profit and ROI on any product | No | Yes, with referral and WFS fees |
| Competing sellers and their stock | No | Yes, plus who wins the Buy Box |

| Price | Free | 14-day free trial, then paid |
Use the Walmart Seller app after you've bought inventory. Use Margenos before. On any Walmart.com product page, the Margenos Chrome extension shows the referral and WFS fees, your profit and ROI, the most you can pay, a sales estimate, every competing seller with their stock, and price and Buy Box history. In a store, the Android app scans the barcode and shows the same numbers. Because you don't need a seller account, you can research products while your Walmart application is still under review.
If you're new to the numbers, our guide on how to calculate Walmart profit walks through the math, and the Walmart profit calculator does it for one item.

Yes. Walmart says you can add items to your catalog, view item details and update pricing and inventory in the app. Larger catalog work is still easier in Seller Center on a computer.

No. Margenos is an independent product research tool from Lemont Holdings LLC and is not affiliated with Walmart. Many sellers use both: Margenos to pick products and the Walmart Seller app to manage orders.
