How to choose an ecommerce platform: a buyer's guide
A clear framework for choosing the right ecommerce platform: hosted vs open-source vs marketplace, the costs that matter, must-have features and how to avoid lock-in.
Your platform is the foundation of your store. You can change it later, but migrations take time and money, so it’s worth choosing carefully. The good news: you only need to answer a handful of questions to narrow dozens of options down to two or three.
The four types of platform
Hosted (SaaS) platforms such as Shopify, BigCommerce, Wix, Squarespace and Square Online run everything for you: hosting, security, updates and checkout. You pay a monthly subscription and usually payment processing fees. They suit most beginners and many growing brands.
Open-source platforms such as WooCommerce (a free WordPress plugin) give you the code. You choose the hosting, can customise anything and own every part of the stack. The trade-off is responsibility: updates, security, backups and plugin compatibility are yours to manage, or your developer’s.
Marketplaces such as Etsy, Amazon and eBay bring buyers to you. They’re excellent for testing demand, but you compete next to rivals on the same page, follow the marketplace’s rules and don’t own the customer relationship.
Creator platforms such as Payhip, Sellfy and Gumroad specialise in digital downloads, courses and memberships. They’re the fastest route for selling digital goods.
Many successful sellers combine types: their own store as the home base, plus a marketplace for discovery.
Five questions that decide it
1. What exactly are you selling?
Physical products with variants and shipping need solid inventory and shipping tools. Digital goods need secure file delivery and licence keys. Services need bookings. Large catalogues and wholesale need bulk management and B2B pricing. Start here, because it eliminates options fast.
2. How much maintenance will you accept?
Be honest. If you don’t want to think about servers and updates, choose hosted. If you have a developer or enjoy tinkering, open-source opens doors.
3. What will it really cost at your volume?
Compare total cost, not the headline plan price. Add:
- the monthly plan
- payment processing (a percentage plus a fixed fee per order)
- any extra transaction fee charged for using a third-party payment provider
- paid apps, plugins and theme licences
- hosting, security and developer time for self-hosted stores
A free plan with a high per-sale fee can cost more than a paid plan once you’re selling regularly. Our fee calculator shows the crossover point.
4. Which features are non-negotiable?
List the must-haves before you look at demos: subscriptions, product bundles, product options or personalisation, multi-currency and multi-language, local payment methods, point of sale, wholesale price lists, or integrations with your accounting and shipping tools. Then confirm each one is built in or available through a well-reviewed app.
5. Can you leave?
Check that you can export products, customers and orders (usually as CSV files) and that your domain is yours. Avoid anything that makes leaving painful.
Red flags when evaluating platforms
- Themes that look great on desktop but cramped on a phone
- Core features that are only available through many paid add-ons
- Unclear fee pages or long contracts
- Slow page loads on the platform’s own demo stores
- Weak or slow support channels on lower plans
A simple decision shortcut
- Digital-only? Start with a creator platform.
- Handmade, testing demand? Start on a marketplace and build your own store alongside it.
- Sell in person as well? Prioritise a platform with strong point of sale.
- Physical brand planning to grow? A major hosted platform is the safe default.
- Need full control or heavy content? WooCommerce.
- Large catalogue or B2B? Look at BigCommerce and Shopify’s higher tiers.

Use free trials properly
Most hosted platforms offer a trial. Don’t just click around: add three real products, set up shipping for your main region, connect a payment method in test mode and place a test order on your phone. An hour of real setup tells you more than a week of reading reviews.
