The best ecommerce platforms for small businesses

The UK ecommerce market is one of the most mature in the world, and online shopping now accounts for around a third of retail sales and that share is rising – choosing the right platform can help sellers tap into this growth. In 2026, the best platforms for UK ecommerce websites enable multi-channel integration, AI-driven personalisation, and the ability to scale internationally as well as locally. Our guide below explores some of the top platforms to help businesses make an informed decision.

Ecommerce platforms vs marketplaces

What is the difference between hosted ecommerce websites and online stores like Amazon and Etsy? Platforms like Shopify and WooCommerce allow businesses to build and operate branded online stores on their own websites, while ecommerce marketplaces offer shopfronts on their platforms. Marketplaces provide small businesses with access to their large international customer bases, but limit control over branding, pricing, and customer data – many small businesses can use marketplaces to complement an ecommerce website.
