Multichannel Selling

Walmart Marketplace has grown from a closed, invite-only platform into one of the fastest-growing third-party marketplaces in the United States, and it now welcomes applications from sellers who can serve American shoppers. For sellers already running on Amazon, Shopify or eBay, it represents a large, lower-competition audience with no monthly subscription fee to get started. The trade-off is a tighter approval process and a marketplace that rewards competitive pricing and reliable delivery above almost everything else. This guide walks you through everything you need to start selling on Walmart Marketplace in 2026: how the application works, what it actually costs, how to choose between Walmart Fulfillment Services and shipping yourself, how to list products and win the Buy Box, and how to keep Walmart in sync once it becomes one channel among several.

Choosing between BigCommerce and Shopify is the platform decision that shapes the next three years of your store: your fees, your apps, your theme, your URL structure, and how easily you can scale to multichannel selling all flow from it. Shopify powers more than 4.8 million stores worldwide and has become the default starting point for new D2C brands. BigCommerce takes a different angle — fewer but more powerful built-in features, 0% transaction fees on every plan, and tighter B2B support — and quietly powers names like Skullcandy, SoloStove, and Burrow. This guide walks through 2026 pricing, fees, features, headless support, and the multichannel reality so you can pick the right starting point — and know when to layer a multichannel order management system above either.

If you sell the same product on Shopee, Lazada, and your own Shopify store, you are already doing price segmentation — whether you realise it or not. Every marketplace has different commission rates, different buyer demographics, and different competitive landscapes. Setting a single price across all of them leaves money on the table.

Shopify or Amazon? It’s one of the most common questions new ecommerce sellers face — and in 2026, the answer is less obvious than ever. Shopify powers over 4.8 million online stores worldwide, giving sellers complete control over their brand and customer data. Amazon, meanwhile, attracts 310 million active buyers and handles everything from warehousing to delivery through FBA. One gives you ownership; the other gives you an audience. This guide breaks down the real differences in fees, fulfilment, control and growth potential so you can make a decision that fits your business — not just your budget.
