This is not a traditional platform comparison. Shopify and Amazon are fundamentally different things. Shopify is a platform for building your own online store. Amazon is a marketplace where you sell alongside millions of other sellers. Comparing them directly is like comparing owning a shop on the high street with renting a stall in a massive market hall.
Both have genuine advantages. Both have real trade-offs. And the smartest UK ecommerce brands do not choose one or the other — they use both strategically, with each channel serving a distinct purpose in their growth strategy.
A fundamentally different question
When you sell on Shopify, you are building a brand. You own the customer experience from first click to delivery. You control the design, the messaging, the pricing, and the post-purchase relationship. You build equity in your own domain, your own brand, and your own customer list.
When you sell on Amazon, you are accessing an existing audience. Amazon has over 300 million active customer accounts globally, with tens of millions in the UK. You benefit from Amazon's traffic, trust, and logistics infrastructure. But you operate within Amazon's rules, compete on Amazon's marketplace, and ultimately build equity in Amazon's platform rather than your own.
Neither approach is wrong. But understanding this fundamental distinction is essential before comparing the specifics.
Brand ownership
On Shopify, your store is yours. Your domain, your design, your brand experience — every element communicates your brand identity. Customers associate their purchase experience with your brand, not with Shopify. This builds brand equity that compounds over time.
On Amazon, your brand exists within Amazon's ecosystem. Your product listings follow Amazon's template. Your brand appears alongside competitors, often directly. Amazon controls the customer experience from checkout to delivery. Customers often remember buying from Amazon, not from your brand.
Amazon Brand Registry and A+ Content provide some brand differentiation, but you are still operating within Amazon's constraints. For brand-driven businesses where customer perception matters, a Shopify store provides incomparably more control.

Customer data and relationships
This is perhaps the most significant strategic difference.
On Shopify: You own all customer data. Email addresses, purchase history, browsing behaviour, preferences — everything. You can build email marketing lists, create Klaviyo email flows, run remarketing campaigns, and build long-term customer relationships. Customer lifetime value is yours to develop.
On Amazon: Amazon owns the customer relationship. You receive order fulfilment data but not customer email addresses for marketing purposes. You cannot email Amazon customers directly, run remarketing ads to them (except through Amazon's own advertising platform), or build a direct relationship outside of Amazon's ecosystem.
For brands focused on long-term customer relationships and repeat purchase revenue, this data ownership difference is critical. A customer who purchases through your Shopify store can become a lifetime customer through email marketing, loyalty programmes, and direct engagement. An Amazon customer is Amazon's to retain.
Fees and margins
Amazon's fee structure significantly impacts margins compared to selling through your own Shopify store.
| Fee component | Shopify | Amazon |
|---|---|---|
| Monthly subscription | £25-£399/month | £25/month (Professional) |
| Referral/transaction fee | 1.5-2.5% (payment processing) | 7-15% (category dependent) |
| Fulfilment | Your responsibility | £2-£8+ per unit (FBA) |
| Storage | Your responsibility | Variable (FBA monthly + long-term) |
| Advertising | Optional (own channels) | Often essential (Amazon PPC) |
For a product selling at £30, typical Amazon fees (referral + FBA) might total £8-12 per unit. On Shopify, payment processing fees would be approximately £0.50-£0.75 per unit. The margin difference is substantial and compounds with volume.
However, Amazon's fees include fulfilment, which you would need to arrange and pay for separately when selling through Shopify. When you factor in your own warehousing and shipping costs, the margin gap narrows — but Shopify still typically provides higher per-unit margins.
Traffic and discovery
Amazon's biggest advantage is built-in traffic. Millions of UK shoppers search for products on Amazon every day. If you list a product in a popular category with good reviews and competitive pricing, you will get visibility without spending money on advertising or SEO.
On Shopify, you need to drive your own traffic. This means investing in SEO, paid advertising, social media marketing, email marketing, and content creation. Building traffic to your own store takes time, effort, and investment. There is no built-in audience.
For new brands with limited marketing budgets, Amazon's built-in traffic is genuinely valuable. For established brands with existing audiences and marketing capabilities, driving traffic to your own Shopify store provides better long-term returns because you capture customer data and build direct relationships.
Fulfilment and logistics
Amazon FBA (Fulfilment by Amazon) is one of the platform's most compelling features. You send inventory to Amazon's warehouses, and they handle picking, packing, shipping, and returns. Prime eligibility provides fast delivery that most independent brands cannot match. FBA is operationally convenient and provides a logistics infrastructure that would be prohibitively expensive to replicate.
On Shopify, you manage your own fulfilment or partner with a third-party logistics (3PL) provider. This gives you more control over the unboxing experience, packaging, and delivery messaging, but requires more operational management. Shopify integrates with various fulfilment services and international selling solutions.
Control and risk
Selling on Amazon involves platform risk. Amazon can change its fee structure, algorithm, or policies at any time. Sellers can have listings suppressed or accounts suspended with limited recourse. Amazon can enter your product category as a competitor. These risks are real and have affected many UK sellers.
On Shopify, you control your store. Shopify does not compete with you, cannot suppress your listings, and changes to the platform are generally incremental and backwards-compatible. The risk profile is fundamentally different.
SEO and content marketing
Your Shopify store can be a hub for content marketing — blog posts, buying guides, lookbooks, and educational content that drives organic traffic and builds brand authority. This content ranks in Google and drives long-term, sustainable traffic.
Amazon product listings rank in Amazon's search engine but have limited visibility in Google search results. You cannot build a content marketing strategy on Amazon. For brands investing in long-term organic growth, a Shopify store is essential.
Using both strategically
The most successful UK ecommerce brands use both channels with a clear strategy for each:
Amazon: Use for product discovery, volume sales, and reaching customers who prefer buying on Amazon. Accept the lower margins as a customer acquisition cost. Use Amazon advertising to drive visibility in competitive categories. Optimise listings for Amazon's algorithm.
Shopify: Use as your primary brand platform. Drive customers from Amazon to your own store through brand building, insert cards, and social media. Build email lists and customer relationships. Offer exclusive products, loyalty programmes, and subscription options that are only available on your own store.
This dual-channel approach treats Amazon as an acquisition channel and Shopify as a retention channel. The goal is to convert Amazon customers into direct customers over time. For building a strong Shopify store, working with a specialist development team ensures your brand experience is compelling enough to attract customers away from marketplace convenience.
UK market specifics
Amazon UK is the third-largest Amazon marketplace globally, with strong consumer adoption. UK shoppers are comfortable buying on Amazon and often start product searches there. Prime membership is widespread, and next-day delivery has become an expectation.
For UK brands, Amazon UK provides access to a massive domestic audience. Shopify provides the platform to build a brand that resonates with UK consumers who increasingly value sustainability, brand story, and direct relationships with the brands they buy from.
Both platforms handle UK VAT, comply with UK consumer protection regulations, and support GBP pricing. Amazon handles customer service for FBA orders; Shopify stores require you to manage customer service directly through tools like well-designed contact pages and support integrations.
When Amazon makes sense
Amazon is the right primary channel when:
- You sell commodity products where brand differentiation is limited
- Your products compete primarily on price
- You want to validate product-market fit before investing in a brand
- You have limited marketing budget and need immediate access to buyers
- Your products benefit significantly from Prime delivery expectations
Shopify is the right primary channel when:
- Brand identity and customer experience are core to your business
- You want to build long-term customer relationships through email marketing and loyalty
- Your margins cannot absorb Amazon's referral and fulfilment fees
- You sell products that benefit from storytelling, lifestyle imagery, and editorial content
- You want to own your customer data and build an asset independent of any marketplace
The verdict
Shopify and Amazon are not competitors — they are complementary channels serving different strategic purposes. For UK brands building long-term value, a Shopify store should be the primary platform for brand building, customer relationships, and higher-margin direct sales. Amazon should be used strategically for discovery, volume, and reaching customers who prefer marketplace shopping.
Brands that rely solely on Amazon are building on rented land. Brands that ignore Amazon are missing a significant customer acquisition channel. The smartest approach is to use both with clear intent: Amazon for acquisition, Shopify for retention and brand equity.
