OnBuy has become one of the world’s fastest growing online marketplaces, with impressive growth of 800% year on year! Launched in 2016, the UK-based marketplace prides itself on offering a transparent selling service that puts small and large businesses on a level playing field.

The rapidly expanding marketplace doesn’t sell its own stock and has pledged not to compete with their sellers, focusing instead on helping them grow, which encourages them to list more products. OnBuy believes it spotted a gap in the market for online marketplaces to truly support SMEs (small and medium-sized enterprises).

With two seller packages to choose from, OnBuy keeps it simple: Standard, costing £19 a month, and Partner, at £39 a month. Commission rates range from 5-9%, depending on the product category. OnBuy offers low selling fees and no listing fees!


Selling on OnBuy gives your brand and products instant exposure to a huge audience of almost 7 million monthly users! It also provides a Subscription Waiver Guarantee to give sellers time to integrate and list their products without being charged a recurring subscription fee until sales pick up.

OnBuy is proud of its claim of paying its fair share of tax, with no overseas offices diverting funds to other countries. The majority of OnBuy sellers are also based in the UK.

If you’re seeking quick sales or to drive more traffic to your product listings, our advertising services offer the perfect solution.


OnBuy is planning a huge global expansion and aims to generate £2 billion in sales by 2024! In 2020 alone, its sales grew from £24m to £200m!

Customers can purchase a range of millions of products swiftly and securely through OnBuy, and with an average rating of 4.7 out of 5 on Trustpilot from over 25,000 customer reviews, they clearly approve!

A partnership with PayPal offers customers and sellers a better experience, with a simple and secure checkout process. OnBuy doesn’t hold sellers’ money either — subject to PayPal’s security checks, customer payments land straight into the seller’s PayPal account.
