Sell in United Kingdom

Europe's most developed e-commerce market. Seven platforms. One operational view.

The United Kingdom is one of the world's largest and most mature e-commerce markets—over £150 billion in annual online sales and 60 million digital shoppers. British consumers are comfortable buying online, expect fast delivery, and shop across multiple platforms. Unlike markets dominated by a single player, this landscape is genuinely diverse: Amazon leads, but eBay remains strong, OnBuy is growing, TikTok Shop is reshaping social commerce, and vertical platforms serve specific categories.

Vastyn connects all seven major platforms into one operational view—unified inventory, consolidated orders, complete VAT visibility.

Seven platforms. One dashboard. Real-time sync. The complexity of British e-commerce, simplified.

This is for you if

  • <50 orders/month, prefer manual processes
  • Need marketplace account setup (we connect existing accounts)
  • Need full WMS (we integrate with them)

What Sellers Say
“Managing seven marketplaces was killing us. Amazon, eBay, OnBuy, TikTok Shop, our Shopify store—every platform had its own dashboard, its own inventory count, its own order process. Black Friday last year was a disaster. This year, everything flows through Vastyn. Same stock, same orders, one view. We actually enjoyed the peak season for the first time.”

FAQ

Common questions about United Kingdom

No. International sellers can sell on marketplaces using home country registration. You'll likely need VAT registration if storing goods here or selling above thresholds.
20% on most consumer goods. For overseas sellers shipping goods under ÂŁ135, marketplaces collect VAT at checkout. For higher-value goods or locally-stored inventory, you'll need VAT registration. Vastyn tracks VAT across all platforms.
Start with Amazon for reach and volume. Add eBay for specific categories. Consider OnBuy for lower fees. TikTok Shop for younger demographics. Most successful sellers operate across multiple platforms—that's what Vastyn makes manageable.
Separate product compliance (UKCA marking), VAT rules, and customs procedures for EU shipments. Goods from EU may face delays and duties. Many sellers maintain separate UK and EU inventory. Vastyn manages both.
Yes, but British consumers expect fast delivery. Consider FBA or local fulfilment for competitive delivery times. Cross-border from EU has post-Brexit customs considerations.
30-60 minutes for full multi-channel setup. If you already have seller accounts, connection is immediate.
