Connect your Shopify store to OnBuy for automatic product, order, and inventory sync across the UK and EU markets.
OnBuy is one of the UK’s fastest-growing marketplaces, with over 150 million pounds in sales in 2024 and expansion into 12 European countries. We’re building a Shopify integration that will let you manage your OnBuy business without leaving your Shopify admin. Product listings, orders, inventory, and pricing: all synchronized automatically.
The app is currently in development. Sign up below to get notified when it launches.
Push your Shopify products to OnBuy using your existing product data. Titles, descriptions, images, pricing, and variants will map to OnBuy listings. Update a product in Shopify and the change syncs to OnBuy. No manual duplicate entry across platforms. Learn more →
OnBuy orders will import directly into your Shopify admin. Fulfill them using your existing workflow: pick, pack, ship, add tracking. The tracking information syncs back to OnBuy automatically so customers can follow their delivery. Learn more →
Stock levels will stay synchronized between Shopify and OnBuy. A sale on either platform immediately adjusts the available quantity on the other. Restocks, returns, and manual adjustments in Shopify all propagate to OnBuy. No more overselling. Learn more →
Keep your OnBuy prices in sync with Shopify. When you change a price in Shopify, the update pushes to your OnBuy listing. Useful for sales, seasonal pricing, or cost adjustments you need reflected across both platforms.
OnBuy is live in the UK and 12 European countries including Germany, France, Spain, Italy, and the Netherlands. The integration will support all OnBuy markets from a single Shopify store and a single OnBuy seller account. Learn more →
When you ship an OnBuy order from Shopify, the carrier and tracking number sync back to OnBuy. Customers get their tracking details on the OnBuy platform. Your seller metrics stay healthy because dispatch confirmations are sent on time.
OnBuy requires GTINs (barcodes) for every listing. The integration will use your Shopify product barcodes to match and create OnBuy listings. Products are matched by barcode, keeping your catalog consistent across both platforms.
Every sync action will be logged with clear status messages. See what synced, when, and troubleshoot any issues without guessing what went wrong.
OnBuy charges category-based commissions from 5% to 15%, with most categories between 5% and 9%. No listing fees. No per-item charges. Subscriptions start at 25 pounds per month. See how OnBuy compares to Amazon →
Unlike Amazon, OnBuy doesn’t sell its own products. There are no private-label brands competing for the same customers. OnBuy makes money from seller commissions, so its incentives are aligned with yours.
OnBuy has no sponsored listings or pay-per-click advertising. Products rank based on price, seller rating, and delivery speed. You compete on merit, not on ad spend.
Over 36 million products. More than 11,000 active sellers. 3.5 million monthly visits. 50% year-over-year sales growth in early 2025. OnBuy is targeting 1 billion pounds in total GMV within three years, backed by European expansion across 12 countries.
