OnBuy Fees Explained: What Sellers Need to Know in 2026

## Overview of the OnBuy Fee Structure Understanding marketplace fees is essential for any seller looking to maintain healthy profit margins. OnBuy has built its reputation partly on offering a straightforward, competitive fee structure that undercuts many rival platforms. This guide breaks down every cost you can expect when selling on OnBuy in 2026. The core fees on OnBuy consist of two main components: a category-based sales commission and a payment processing fee. Unlike some competitors, OnBuy does not charge listing fees, monthly subscription fees for basic accounts, or hidden charges. You only pay when you make a sale, which makes it a genuinely low-risk platform for new and established sellers alike. ## Sales Commission Rates OnBuy charges a commission on each completed sale, calculated as a percentage of the total order value (including delivery charges). The commission rate varies by product category: - **Electronics and Computing:** Typically around 5% - **Home and Garden:** Around 7% - **Fashion and Clothing:** Around 9% - **Health and Beauty:** Around 7% - **Sports and Leisure:** Around 7% - **Books, Music, and Film:** Around 5-6% - **Toys and Games:** Around 7% These rates are subject to change, so always verify the current rates in the OnBuy Seller Centre for your specific categories. In general, OnBuy's commission rates are lower than equivalent categories on many other UK marketplaces, which gives sellers more room in their pricing strategy. ## Payment Processing Fees In addition to the sales commission, OnBuy applies a payment processing fee to each transaction. This covers the cost of handling buyer payments securely through the platform. The payment processing fee is typically around 2% of the transaction value, though this may vary slightly depending on the payment method used by the buyer. This fee is standard across e-commerce and is comparable to what you would pay using a standalone payment gateway on your own website. The key difference is that OnBuy handles all payment processing, fraud protection, and buyer disputes on your behalf, saving you the operational overhead. ## No Listing Fees One of the most significant advantages of OnBuy is the absence of listing fees. You can list as many products as you want without paying per listing. This is a major difference from some other marketplaces where insertion fees can add up quickly, especially if you have a large catalogue or frequently relist items. This zero-listing-fee approach means you can test new products, expand into new categories, and maintain a broad catalogue without worrying about upfront costs eating into your margins before you have made a single sale. ## Seller Subscription Plans OnBuy offers different seller packages that provide additional features and benefits. The standard package is free and includes access to the core selling tools. Premium packages are available for sellers who want enhanced analytics, priority support, and additional promotional features. The cost of these packages varies, so check the OnBuy Seller Centre for the latest pricing and feature comparisons. For most new sellers, the standard package provides everything you need to get started and build your business. Consider upgrading once your sales volume justifies the additional investment. ## How OnBuy Fees Compare to Other Marketplaces When evaluating where to sell, comparing fee structures is crucial. Here is a general comparison: **OnBuy vs Amazon UK:** Amazon charges a monthly subscription fee for professional sellers plus a referral fee that ranges from 7% to 15% depending on category. When you factor in Amazon's FBA fees for storage and fulfilment, the total cost per sale can be significantly higher than OnBuy. **OnBuy vs eBay UK:** eBay charges insertion fees after a free listing allowance, a final value fee of 10-12% on most categories, and additional fees for promoted listings. OnBuy's simpler fee structure is often more cost-effective, particularly for high-volume sellers. **OnBuy vs Etsy:** Etsy charges a listing fee per item, a transaction fee of 6.5%, and a payment processing fee. For sellers whose products fit both platforms, OnBuy typically works out cheaper per transaction. The lower overall fee burden on OnBuy means more profit per sale, which can be reinvested into competitive pricing, better stock, or marketing efforts. ## Factoring Fees Into Your Pricing Strategy To maintain profitability, you need to account for all marketplace fees when setting your prices. Here is a practical approach: 1. **Calculate your landed cost.** This includes the product cost, shipping to your warehouse, packaging materials, and any import duties. 2. **Add the OnBuy commission.** Apply the relevant category commission rate to your target selling price. 3. **Add the payment processing fee.** Include the approximately 2% processing charge. 4. **Include your delivery cost.** Whether you offer free delivery or charge separately, factor in the actual cost of shipping to the buyer. 5. **Set your profit margin.** After all costs, ensure your selling price leaves an acceptable margin. Most experienced sellers target a minimum net margin of 15-20% after all fees. A repricing tool like [Re-Pricer](https://re-pricer.com) can help automate this process by setting minimum price floors that account for your costs and desired margin, while dynamically adjusting prices to remain competitive. This ensures you never sell below profitability, even in a highly competitive category. ## Maximising Your Margins on OnBuy Beyond understanding the fee structure, there are practical steps to improve your profitability: - **Negotiate better supplier pricing** as your volume grows to reduce your cost of goods. - **Optimise your packaging** to reduce shipping costs without compromising product safety. - **Focus on higher-margin categories** where the commission rate is lower relative to your selling price. - **Use automated repricing** to capture the buy box at the optimal price point rather than racing to the bottom. - **Bundle products** where appropriate to increase average order value and spread fixed costs across more items. Understanding and managing your OnBuy fees is not just about knowing the percentages. It is about building a pricing strategy that accounts for every cost, protects your margins, and positions you competitively in the marketplace.
