Shopify to OnBuy Integration

Sell on the UK marketplace that never competes with its own sellers

Overview

OnBuy is one of the fastest-growing marketplaces in the UK, built on a seller-friendly model that guarantees the platform never sells its own products. This means no competition from the marketplace itself — a refreshing change from Amazon and eBay.

With millions of UK shoppers and competitive fee structures, OnBuy offers Shopify merchants an excellent channel for the British market. The platform supports all major product categories and has been expanding rapidly since its launch.

Marqetir's integration connects your Shopify store to OnBuy with automatic product listing, GBP pricing, and order synchronization — letting you tap into the UK market without additional operational overhead.
