Shopify and Amazon FBA represent two fundamentally different approaches to selling online. This is not a comparison between two similar tools — it is a comparison between two entirely different business models. Understanding this distinction is crucial because the right choice (or combination) shapes your margins, your brand, your customer relationships, and your long-term business value.
I have worked with brands that sell exclusively on Amazon, brands that sell exclusively through Shopify, and brands that use both channels strategically. Each approach has genuine advantages and real trade-offs. There is no universally correct answer — but there is a right answer for your specific situation.
Fundamental business models
Shopify is an ecommerce platform that lets you build and run your own online store. You own the domain, the brand experience, the customer data, and the marketing relationship. You are responsible for driving traffic, handling fulfilment (or partnering with a 3PL), and managing the entire customer experience from first visit to post-purchase.
Amazon FBA (Fulfilment by Amazon) is a service within Amazon's marketplace. You send your products to Amazon's fulfilment centres. When a customer orders, Amazon picks, packs, ships, and handles customer service and returns. Your products are listed on Amazon's marketplace alongside millions of other sellers, benefiting from Amazon's massive customer base and Prime delivery network.
The core trade-off is straightforward: Amazon gives you access to traffic and handles logistics, but takes a substantial cut and owns the customer relationship. Shopify gives you complete control and better margins, but you must build everything yourself.
Fees and costs
Amazon FBA fees (UK)
Amazon's fee structure is complex and varies significantly by product category, size, and weight:
- Professional seller subscription: £25/month (or £0.75 per item on the Individual plan)
- Referral fees: 7-15% of the sale price depending on product category (most categories are 15%)
- FBA fulfilment fees: From approximately £2.04 for small/light items to £10+ for larger items
- Monthly storage fees: £0.69-£1.20 per cubic foot (higher during Q4 peak season)
- Long-term storage fees: Additional charges for inventory stored beyond 365 days
- Advertising: Amazon PPC costs vary but are increasingly necessary for visibility
For a typical product selling at £25 in a 15% referral fee category, total Amazon FBA fees (referral + fulfilment + storage) often amount to £8-12 per unit — roughly 32-48% of the sale price. This is before advertising costs.
Shopify fees
- Platform subscription: £25-£399/month depending on plan
- Payment processing: 2% + £0.25 per transaction (Shopify Payments on Basic)
- Fulfilment: Variable — self-fulfilment, 3PL, or services like ShipBob
- Marketing: Variable — SEO, paid ads, email marketing
For the same £25 product on Shopify Basic, payment processing costs approximately £0.75. Fulfilment costs depend on your method but typically range from £2-5 per order for a standard-sized item through a 3PL. Total platform and fulfilment costs are often 12-25% of the sale price — significantly less than Amazon's combined fees. For a full breakdown, see our guide on what a Shopify store build should cost.
Brand control and ownership
On Amazon, your product listing exists within Amazon's ecosystem. Your brand is secondary to the Amazon brand. Product pages follow Amazon's standardised template. Customer communications go through Amazon. Packaging arrives in Amazon-branded boxes. The customer's experience is "I bought this on Amazon" — not "I bought this from your brand."
Amazon's Brand Registry and A+ Content provide some brand customisation — enhanced product descriptions, brand stories, and storefronts within Amazon. But these are limited compared to the complete brand control you have on Shopify.
On Shopify, every touchpoint is your brand. Your domain, your design, your packaging, your emails, your customer service. Customers build a relationship with your brand specifically. This brand equity has tangible business value — branded businesses command higher valuations, generate more repeat customers, and can build community around their products.
For brands that view themselves as more than just a product — where storytelling, community, and customer experience are differentiators — Shopify is essential. For sellers focused primarily on moving product volume, Amazon's standardised approach removes the burden of brand building. For more on this strategic decision, see our article on DTC versus marketplace strategy.
Traffic and customer discovery
Amazon has over 300 million active customer accounts globally and is the starting point for over 50% of product searches in many markets. When someone wants to buy a product, they often search Amazon before Google. This built-in demand is Amazon's single greatest advantage.
Your product can appear in Amazon search results, recommended products, sponsored placements, and category browsing without you building any marketing infrastructure. The traffic is there — your job is to optimise your listing to capture it.
Shopify provides zero built-in traffic. Every visitor must be attracted through your own marketing efforts — SEO, paid advertising, social media, email marketing, content marketing, or partnerships. Building traffic takes time, money, and expertise.
However, owned traffic has compounding value. An email subscriber you acquire today can be marketed to for years. An SEO ranking you build persists. A social media following you grow is an ongoing asset. Amazon traffic is rented — your visibility depends on Amazon's algorithm, which can change at any time.
Fulfilment and logistics
Amazon FBA's fulfilment infrastructure is one of the best in the world. Two-day Prime delivery, excellent packaging, reliable tracking, and professional customer service — all handled by Amazon. For sellers who do not want to manage fulfilment operations, FBA removes that entire complexity.
FBA also enables Prime eligibility, which significantly increases conversion rates. Many Amazon customers filter results by Prime-eligible products only, meaning non-FBA sellers miss substantial traffic.
On Shopify, fulfilment is your responsibility. Options include self-fulfilment (packing and shipping from your own premises), third-party logistics providers (3PLs), or fulfilment services. You can also use Amazon's Multi-Channel Fulfilment (MCF) to fulfil Shopify orders from your FBA inventory — getting Amazon's logistics without selling exclusively on the marketplace.
Self-fulfilment gives you complete control over the unboxing experience — custom packaging, inserts, handwritten notes — which can be a powerful brand-building tool. FBA gives you logistics excellence at scale but in generic Amazon packaging.
Customer data and marketing
This is one of the most consequential differences between the two platforms.
Amazon does not give you customer email addresses or contact information for marketing purposes. You cannot build an email list from Amazon sales. You cannot run retargeting campaigns against Amazon customers. You cannot create a loyalty programme for your Amazon buyers. The customer relationship belongs to Amazon, and they guard it carefully.
On Shopify, you own all customer data. Email addresses, purchase history, browsing behaviour, and preferences are all available for marketing. You can build email lists, create segmented campaigns, run retargeting ads, build loyalty programmes, and develop personalised customer experiences. This data ownership is fundamental to building a sustainable, profitable ecommerce business. For insights on leveraging customer data effectively, see our guides on retention versus acquisition and abandoned cart sequences that convert.
Competition and pricing pressure
Amazon is intensely competitive. Your product listing appears alongside dozens of competitors offering similar products. Price comparison is effortless for buyers — they can see competing prices with a single scroll. This creates relentless downward pressure on pricing, which compresses margins.
Amazon also allows other sellers to list against your ASIN, meaning competitors can sell on your own product listing. Counterfeit products, copycats, and aggressive pricing tactics are ongoing challenges for Amazon sellers. Some categories have become so competitive that profitability is extremely difficult for new entrants.
On Shopify, competition exists in the broader market but not directly on your storefront. Your product page showcases only your brand and products. Customers who visit your store are engaging with your brand exclusively. Price comparison requires visiting another website. This environment supports premium pricing and brand-based purchasing decisions.
Scalability
Amazon FBA scales logistics effortlessly. As your sales increase, Amazon handles the additional fulfilment volume without you hiring staff, expanding warehouse space, or managing shipping complexity. International expansion through Amazon is relatively straightforward — Amazon operates marketplaces in multiple countries with established fulfilment networks.
Shopify scales the storefront seamlessly — from first sale to millions in annual revenue, the platform handles growing traffic and order volumes. Scaling fulfilment requires more planning — upgrading from self-fulfilment to a 3PL, managing multiple warehouse locations, and optimising shipping operations.
For rapid scaling with minimal operational complexity, Amazon FBA has a clear advantage. For sustainable scaling with brand equity and customer ownership, Shopify provides a stronger foundation.

Risk factors
Amazon platform risk
Amazon can suspend your selling account, change fees, modify its algorithm, or alter policies at any time. Sellers have experienced sudden account suspensions — sometimes due to errors — that immediately halt all revenue. Your business exists on Amazon's platform, subject to their rules. This concentration risk is real and has impacted many established sellers.
Shopify platform risk
Shopify is less likely to suspend your store without cause, and your brand, customer data, and domain are yours regardless. Platform risk on Shopify is primarily operational — traffic loss from algorithm changes (Google, social media), marketing channel disruption, or changes to third-party app pricing. These risks are more gradual and more within your control.
Diversification across channels is the best risk mitigation strategy. Relying entirely on either platform creates vulnerability that a multi-channel approach addresses.
The hybrid strategy
Many successful ecommerce brands use both Shopify and Amazon strategically:
- Amazon for discovery: Use Amazon's traffic to introduce products to new customers
- Shopify for brand building: Drive repeat customers to your Shopify store where you own the relationship
- FBA for fulfilment: Use Amazon MCF to fulfil Shopify orders, leveraging Amazon's logistics without selling on the marketplace
- Separate product strategies: Sell best-sellers on Amazon, keep exclusive products on Shopify to drive direct traffic
- Pricing differentiation: Offer bundles, subscriptions, or personalisation on Shopify that are not available on Amazon
The hybrid approach requires more operational complexity but provides the benefits of both models while mitigating the risks of dependence on either.
UK-specific considerations
Amazon UK marketplace
Amazon.co.uk is a mature marketplace with strong consumer adoption. FBA fulfilment centres throughout the UK provide fast domestic delivery. Pan-European FBA allows stock distribution across EU fulfilment centres for European sales, though post-Brexit customs considerations apply.
VAT implications
Both platforms require UK VAT registration for UK-based sellers above the threshold. Amazon handles VAT collection on behalf of sellers for UK consumer sales. On Shopify, you manage VAT configuration directly, though the platform supports VAT-inclusive pricing and automatic calculations.
Consumer trust
UK consumers have high trust in Amazon — Prime membership is widespread and the returns process is well-understood. Shopify stores need to earn trust individually through professional web design, clear policies, and social proof. For new brands without existing recognition, Amazon's trust halo provides a significant conversion advantage.
The verdict
Choose Shopify if:
- Building a brand with long-term equity is your goal
- You want to own customer relationships and data
- Higher margins per sale are important to your business model
- You have marketing capabilities to drive your own traffic
- Differentiated products or experiences are your competitive advantage
- You want control over pricing without marketplace competition pressure
Choose Amazon FBA if:
- You want immediate access to a massive customer base
- Fulfilment logistics are a barrier you want to eliminate
- Your products compete well on features and price in a marketplace environment
- You prefer operational simplicity over brand control
- Fast scaling with minimal infrastructure investment is the priority
- Prime eligibility is important for your target customers
Use both if:
- You want marketplace distribution alongside your own branded store
- You can manage the operational complexity of multi-channel selling
- You want to diversify revenue across channels to reduce platform risk
For most brands building long-term value, a Shopify store should be the foundation — even if Amazon is part of the revenue mix. The brand equity, customer ownership, and margin advantages compound over time in ways that marketplace selling alone cannot replicate.
