How much does OnBuy charge per sale?

OnBuy charges a category commission of 5–9% plus approximately 2% payment processing. Total variable cost per sale ranges from about 7% to 11%, which is significantly lower than Amazon (7–15% + FBA) or eBay (10–13%). There is also a monthly subscription from £19/mo.

What are the OnBuy subscription plans?

OnBuy offers three plans: Standard (£19/month) with listing limits suitable for small sellers, Premium (£39/month) with higher limits, and Unlimited (£79/month) with no listing restrictions. All plans include the same commission rates.

How do OnBuy fees compare to eBay?

OnBuy is significantly cheaper than eBay. OnBuy commissions (5–9%) are about half of eBay's final value fees (10–13%). Even including OnBuy's monthly subscription and 2% payment fee, total costs are lower for most sellers doing reasonable volume.

Does OnBuy charge payment processing fees?

Yes, approximately 2% per transaction for payment processing. This is separate from the category commission. Total variable cost per sale is commission (5–9%) + payment processing (~2%). This is still competitive compared to most marketplaces.

Is OnBuy available outside the UK?

OnBuy is primarily a UK marketplace. International sellers can sell on OnBuy, but the customer base is predominantly UK-based. If you're targeting multiple European markets, consider combining OnBuy for UK with other regional marketplaces.
