Whether you’re a growing eCommerce brand or just starting out, online Marketplaces are one of the fastest and most effective ways to reach UK consumers. Over 60% of all eCommerce sales in the UK take place through Marketplaces, a number that continues to grow. 

This guide breaks down the key facts and figures to help you choose the best online Marketplaces for your business.

Online marketplaces have become the primary channel for eCommerce sales worldwide. In 2026, marketplaces operating a third-party model are estimated to capture roughly 87% of eCommerce revenue, as brands increasingly leverage multi-seller platforms rather than direct online stores.

Globally, nearly all online shoppers (98%) use at least one marketplace, with Amazon, Temu, SHEIN and eBay among the most frequently visited platforms.

Fulfilment and Delivery for Marketplace Sellers

Each marketplace offers its own fulfilment routes, but these often come with issues when it comes to flexibility, brand control and cost transparency.

Here’s how fulfilment typically works on the major marketplaces:

amazon logos

Amazon

Fulfilment by Amazon (FBA) gives sellers access to Prime delivery and a wide customer base, but can come with strict guidelines, premium fees and limited visibility.

ebay and etsy logos

eBay & Etsy

Most sellers self-fulfil, relying on Royal Mail or standard courier services. This gives more control but can be time-consuming and harder to scale consistently.

OnBuy

Sellers handle their own shipping, offering more freedom but requiring a reliable logistics setup.

TikTok Shop

Now offers “Fulfilled by TikTok,” a new logistics service designed for social commerce. While convenient, it’s still developing and may not suit all product types or volumes.

Integrating multiple marketplaces to your eCommerce profile can make things complex, and give you less control over collections and delivery options which all directly impact operational efficiency and customer satisfaction. If you need one delivery partner for parcel deliveries across your website and all other channels and marketplaces across the globe, GFS is the answer. 

Key Takeaways

  • UK Marketplaces give you access to millions of ready-to-buy consumers.

  • Consider fees, fulfilment and buyer demographics when choosing where to list.

  • Diversifying across 2+ platforms reduces risk and increases visibility.

Fulfilment by Shein (FBS)

Similar to Amazon’s FBA, Fulfilment by Shein handles warehousing, picking, packing, last-mile delivery and returns on behalf of sellers.

Managing multiple marketplaces often adds operational complexity, limiting control over collections and delivery options and placing strain on fulfilment performance and customer experience.

With GFS, you can simplify delivery across your own website and every marketplace you trade on worldwide, using one trusted partner to streamline operations and support scalable growth.

  • UK Marketplaces give you access to millions of ready-to-buy consumers.

“What’s made everything easier for us is our partnership with GFS. Having one portal means we’re no longer juggling multiple carriers or systems. Honestly, I don’t think we’d be coping with our current order volumes, or even considering expanding into marketplaces, without GFS.”
