Multi-Marketplace Strategy: Selling on Amazon, Walmart, and TikTok Shop Simultaneously

A multi-marketplace strategy means selling on Amazon, Walmart Marketplace, and TikTok Shop simultaneously to diversify revenue, reach new customer segments, and reduce dependency on any single platform. In 2026, the smartest brands are not all-in on Amazon. They are leveraging each platform's unique strengths: Amazon for volume and search intent, Walmart for value-conscious shoppers and grocery, and TikTok Shop for discovery-driven impulse purchases. At Marknology, our Kansas City team helps brands expand beyond Amazon into Walmart and TikTok Shop while maintaining strong performance across all channels.

Andrew Morgans on the Startup Hustle podcast: "I built Marknology on Amazon. It is our bread and butter. But telling a brand to put all their eggs in the Amazon basket in 2026 would be irresponsible. Walmart is growing at 30% year over year. TikTok Shop went from zero to billions in two years. You need to be where the customers are, and customers are everywhere now."

Why Should You Sell on Multiple Marketplaces?

The case for multi-marketplace selling in 2026 comes down to three factors:

• Revenue diversification: If 100% of your e-commerce revenue comes from Amazon and Amazon changes a policy, raises fees, or suspends your account, you lose everything overnight.
• Customer reach: Amazon has ~200M US Prime members. Walmart.com has ~150M monthly visitors. TikTok has ~150M US users. These audiences overlap but are not identical. Multi-marketplace gets you in front of customers you would never reach on Amazon alone.
• Platform arbitrage: Each marketplace has different fee structures, advertising costs, and competitive dynamics. A product that is hyper-competitive on Amazon might have wide-open space on Walmart.
• Growth ceiling: Brands that max out on Amazon often discover that adding Walmart and TikTok Shop adds 15-40% incremental revenue.

Diversification is not about abandoning Amazon. It is about not being hostage to Amazon. The brands that survived every major Amazon policy change over the last decade were the ones that had revenue coming from multiple places.-- Andrew Morgans, Marknology

What Makes Amazon the Foundation?

Amazon remains the starting point for most brands for good reason:

• Largest e-commerce marketplace in the US ($700B+ in GMV)
• Highest purchase intent of any platform (people go to Amazon to buy)
• FBA infrastructure handles logistics at massive scale
• Mature advertising platform with Sponsored Products, Brands, Display, and DSP
• Brand Registry provides listing protection and analytics tools
• Subscribe and Save for recurring revenue

At Marknology, we always optimize Amazon first. It is the engine. Walmart and TikTok Shop are the accelerators you bolt on once the engine is running strong.

How Is Selling on Walmart Different from Amazon?

Marketplace Overview

Walmart Marketplace has grown rapidly since opening to third-party sellers in 2020. Key differences from Amazon:

• Lower competition: Walmart has ~150,000 sellers vs. Amazon's 2M+. Less competition per category.
• Different customer: Walmart shoppers tend to be more price-sensitive and value-driven. Average order values are lower.
• Walmart Fulfillment Services (WFS): Similar to FBA but smaller and still evolving. WFS products get the W+ badge (similar to Prime).
• Lower referral fees: Walmart's referral fees are generally 1-3% lower than Amazon's in most categories.
• Less sophisticated advertising: Walmart Connect (their ad platform) is growing but not as mature as Amazon Ads. CPCs are typically lower.

Walmart-Specific Strategies

• Price competitively. Walmart's algorithm heavily weights price. If you are the cheapest option, you get visibility.
• Enroll in WFS for the W+ badge and 2-day shipping promise
• Optimize for Walmart's SEO (different algorithm than Amazon, more weight on price and in-stock rate)
• Use Walmart Connect ads aggressively while CPCs are still low

What Is TikTok Shop and How Does It Work?

TikTok Shop is the marketplace built directly into the TikTok app. It combines social media content with instant purchasing, creating a discovery-driven shopping experience that is fundamentally different from search-driven Amazon.

How TikTok Shop Works

• Creators and brands post video content showcasing products
• Products are tagged directly in the video with a shopping link
• Customers can purchase without leaving the TikTok app
• TikTok's algorithm surfaces products to relevant audiences based on interest and engagement
• Live shopping events drive massive impulse purchase volume

TikTok Shop Strategy

• Content is everything: TikTok Shop performance is directly tied to the quality and quantity of video content. You need consistent, authentic content creation.
• Creator partnerships: TikTok's affiliate program lets creators earn commissions for selling your products. Build a creator network.
• Lower price points win: TikTok's audience skews younger and more impulse-driven. Products under $30 perform best.
• Fulfillment: TikTok offers Fulfilled by TikTok (FBT) or you can self-fulfill. FBT is still early but improving.

Andrew Morgans notes: "TikTok Shop is the wild west right now, and that is exactly why brands should be there. The brands that figure it out early will dominate when the platform matures. That is exactly what happened with Amazon 10 years ago."

How Do You Manage Operations Across Three Platforms?

Inventory Management

This is the biggest operational challenge. You need a centralized inventory management system that syncs stock levels across Amazon FBA, Walmart WFS, and TikTok FBT (or your 3PL). Running out of stock on any platform has consequences. At Marknology, we help brands set up multi-channel fulfillment that prevents stockouts.

Listing Management

Each platform has different listing requirements, character limits, and image specifications. You cannot just copy-paste your Amazon listing to Walmart. Optimize for each platform's algorithm and customer expectations.

Order Management

Use a multi-channel order management system (OMS) to centralize orders from all platforms. This prevents overselling and ensures consistent fulfillment timelines.

Recommended Tools

• Inventory: Skubana, Sellbrite, or ChannelAdvisor for cross-platform inventory sync
• Listings: Platform-native tools plus Listing Mirror or Zentail for cross-listing
• Analytics: Each platform's native analytics plus a centralized dashboard

How Do You Advertise on Each Platform?

Amazon Ads

Mature, sophisticated platform. Use Sponsored Products for bottom-funnel, Sponsored Brands for mid-funnel, and DSP for top-funnel. Most brands spend 60-70% of their total marketplace ad budget on Amazon.

Walmart Connect

Growing rapidly but less sophisticated. Sponsored Products are the primary ad type. CPCs are 30-50% lower than Amazon in most categories. Invest now while competition is low.

TikTok Shop Ads

TikTok Shop uses a combination of organic creator content and paid TikTok ads to drive sales. Product Shopping Ads, Video Shopping Ads, and LIVE Shopping Ads are the main formats. Budget allocation should be 50/50 between creator content and paid amplification.

At Marknology, we recommend starting with 70% of ad budget on Amazon, 20% on Walmart, and 10% on TikTok Shop, then adjusting based on performance.

What Multi-Marketplace Mistakes Should You Avoid?

1. Expanding before Amazon is optimized. If your Amazon business is not profitable and systematized, adding more platforms just multiplies the chaos.
2. Copy-pasting listings. Each platform has different algorithms, customers, and listing requirements. Optimize natively for each.
3. Ignoring platform-specific fulfillment. Using Merchant Fulfilled on Walmart instead of WFS is like using FBM on Amazon. You lose visibility and trust signals.
4. Spreading ad budget too thin. Better to dominate on one platform and be present on others than to be mediocre everywhere.
5. Not tracking profitability by platform. Different fee structures mean different margins. Know your unit economics for each marketplace.
6. Underestimating content needs for TikTok. TikTok Shop requires constant video content. If you do not have a content creation plan, TikTok Shop will not work.

When Should You Expand Beyond Amazon?

You are ready for multi-marketplace expansion when:

• Your Amazon business is profitable with stable operations
• You have reliable supply chain and inventory management
• Your Amazon advertising is optimized (not just spending, but profitable)
• You have the team capacity (or agency support) to manage additional platforms
• Your product has broad appeal beyond Amazon's core demographic

At Marknology, we typically recommend brands start on Walmart first (lower operational complexity, similar to Amazon) and add TikTok Shop once they have a content strategy in place.

Use a centralized inventory management system like Skubana, Sellbrite, or ChannelAdvisor that syncs stock levels across Amazon FBA, Walmart WFS, and your 3PL in real time.

Which marketplace should I expand to first?

Most brands should expand to Walmart first because it is operationally similar to Amazon. TikTok Shop should be second, once you have a content creation strategy in place.

Are Walmart advertising costs lower than Amazon?

Yes. Walmart Connect CPCs are typically 30-50% lower than Amazon Ads in most categories. This makes Walmart advertising a high-ROI opportunity in 2026.
