Every product seller faces the same fork in the road. Do you list on Amazon, Etsy or eBay and tap into millions of ready buyers? Or build your own store, keep more of each sale, and own your customers? Both routes work, and the wrong instinct is to treat it as either/or. Let's weigh them honestly.
The appeal of marketplaces
Marketplaces hand you something precious: an audience. People are already there, wallets out, searching for products like yours. You don't have to build trust from scratch or spend heavily on traffic to make your first sales. For testing a product or earning quick early revenue, that's genuinely valuable.
The catch is what you give up in return. Fees are steep — once you tally selling and referral fees, Amazon and eBay often take 10–15% of each sale, before fulfilment costs. You compete with near-identical listings on the same page, you're bound by the platform's rules, and crucially you don't own the customer relationship.
The case for your own store
Your own store flips the trade-off. You keep far more of each sale, you control the brand, the design and the experience, and you own your customer list — which means you can email, remarket and build loyalty. Over time that ownership compounds into a real, sellable asset.
The cost is traffic. Nobody arrives by default, so you have to earn visitors through SEO, content, social and ads. That takes time and investment, which is why a well-built store backed by sound digital marketing matters so much. Done well, the margins and customer ownership more than repay the effort.
A head-to-head view
| Factor | Marketplace | Own store |
|---|---|---|
| Built-in traffic | High | You build it |
| Fees per sale | High (10–15%+) | Just payment fees |
| Brand control | Limited | Full |
| Customer ownership | Minimal | Yours |
Why most sellers do both
For many UK businesses the smart answer isn't one or the other — it's both, used for what each does best. Use marketplaces to reach new buyers and shift volume, and use your own store to build brand, capture loyal repeat customers, and protect your margins. Some sellers even add a marketplace insert that gently invites buyers to order direct next time.
The practical challenge of selling everywhere is keeping stock and orders in sync, so you never oversell. That's exactly what good inventory and order management tools are built to solve, and it's worth setting up early.
How to decide your mix
If you're just starting and need sales now, a marketplace lowers the barrier. If you're building a brand for the long term, prioritise your own store. Most sellers benefit from starting on one, validating demand, then expanding to the other once they understand their margins and customers.
