Shopify vs Amazon for US Sellers: Newon Lab's Full-Stack Ecommerce Solution

Nearly every product business in the US reaches the same fork in the road: "Do we build our own Shopify store, or sell on Amazon?" It's a fair question. The two platforms work in very different ways, and the right answer depends on your product, margins, brand ambitions and how much control you want.

Here's a straight comparison, plus the approach most successful brands end up taking, with help from a full-stack ecommerce partner like Newon Lab.

The core difference

Amazon is a marketplace. Customers come to Amazon to shop, and you rent space in front of them. Shopify is a platform for building your own store. You own the storefront and the customer relationship, but you have to bring the traffic.

Head-to-head comparison

Traffic

Amazon wins on built-in demand. Millions of high-intent shoppers search it daily. Shopify stores need marketing: SEO, ads, social media, email and influencers.

Fees and margins

Amazon charges referral fees (often around 15%), FBA fulfillment fees, storage fees and advertising costs that add up fast. Shopify has a monthly subscription and payment processing fees, usually leaving higher margin per order, though you pay separately for marketing.

Branding and customer experience

Shopify gives you full creative control over design, content, bundles, loyalty programs and post-purchase flows. On Amazon, your brand lives inside Amazon's template, next to competitors' products.

Customer data

This is a big one. Shopify gives you every customer's email, phone number and purchase history, which you can use for remarketing and repeat sales. Amazon keeps that data to itself.

Risk and control

Amazon can change fees, suspend listings or allow competitors to sell next to you. On Shopify you set the rules, though you're responsible for payments, fraud and support.

Speed to first sale

Amazon can generate sales faster for products with existing search demand. Shopify takes more effort upfront but builds a stronger long-term asset.

When Amazon makes more sense

• You sell commodity or search-driven products (supplements, kitchen tools, accessories)
• You want fast validation of a new product
• Prime shipping speed is critical for your category
• You don't yet have a marketing budget for driving traffic

When Shopify makes more sense

• You have a strong brand story or premium positioning
• You sell subscriptions, bundles or customizable products
• Lifetime value and repeat purchases matter to your business model
• You're building a community through content, TikTok or influencers

The winning answer for most brands: both, connected

The fastest-growing US brands don't pick one. They run a multichannel system:

1. Shopify as the brand hub: the home for your story, best customers, email list and highest margins.
2. Amazon for marketplace demand: capturing shoppers who prefer buying on Amazon.
3. TikTok Shop and Instagram Shopping for social discovery: Shopify integrates with both, so products sync automatically.
4. One inventory and analytics layer: so stock levels, orders and profit are accurate everywhere.

For example, a shopper might discover your product in a TikTok video, check reviews on Amazon, and later buy a bundle on your Shopify site after receiving a welcome email. Every channel plays a role.

FAQ

Can I connect my Shopify store to Amazon?

Yes. Integrations can sync products, inventory and orders, and Amazon's Multi-Channel Fulfillment can ship Shopify orders from FBA inventory.

Is Shopify good for SEO?

Shopify can rank very well with the right site structure, fast performance, quality content and technical SEO, which our team handles.

Should a new brand start on Amazon or Shopify?

If your product has clear search demand, starting on Amazon can validate it quickly. Build your Shopify brand hub at the same time so you own your customers from day one.
