Not yet selling on Walmart? Become a Walmart Seller first here!

Through our affiliate link, you get priority approval. Visit Walmart Marketplace and click “Request to Sell.” You’ll need your business tax ID (SSN not accepted), W-9 or W-8 form, a business bank account, and product information. Once approved, you can set up your catalog and start selling. 

Walmart requires sellers to :

• Possess a U.S. business tax ID and EIN
• Have a U.S. business address and bank account
• Display high-quality product listings with UPCs
• Demonstrate fast and reliable fulfillment history

The approval process usually takes 1 to 4 weeks, depending on the completeness of your application and Walmart’s verification process.

WAMP works in the same way SellerAmp does, but for Walmart. For those who aren’t familiar with SellerAmp, SellerAmp evolved from founder Al Carlton’s deep programming background and his own successful OA, RA and wholesale Amazon selling business. After coming up with creative manual ways to validate whether products were worth his investment, he realized the void in the market and began creating tools to support sourcing activities.

SellerAmp's flagship tool SAS, Sourcing Analysis Simplified, provides key analysis that enables users to make their own, educated decisions on whether to source a product to sell on Amazon. SAS does the heavy lifting on analyzing the product, calculating profit and ROI, looking at its history, other sellers, alerts you should know about and many other data points. Ultimately you have the information you need to make a decision on whether to invest. SAS was so successful, users requested a similar tool for Walmart, thus, WAMP was born!

WAMP makes data-driven decisions easy by showing:

• Estimated monthly sales
• Profit margins & fees breakdown
• Product demand trends
• Competitor analysis

• Profit Calculator - Instantly see ROI, profit margins, and all costs - including shipping and Walmart fees, so you know what you’ll earn and can buy with confidence.
• Historic Charts - WAMP charts track price, Buy Box, reviews, offers, and ratings over time, helping you spot patterns, monitor competition, and make smarter sourcing decisions.
• Offers - Displays competing sellers, their current stock levels, and pricing, giving you a clear view of market competition and potential opportunities.
