OnBuy Seller Support
OnBuy is a UK-based online marketplace that many sellers add as a complementary channel. We help you prepare your account information, get products listed accurately and run dependable day-to-day operations.
How OnBuy selling works in practice
OnBuy uses a product catalog where sellers can often match existing product pages or create new ones. Matching correctly to the right product identifiers avoids listing conflicts and customer confusion.
Selling to UK customers involves expectations around delivery times, returns and consumer rights. Your store policies should be clear and consistent with UK requirements and OnBuy's seller terms.
Day-to-day, sellers are measured on dispatch times, cancellations and customer responses. We provide routines and reporting so you can keep standards steady as volume grows.

Who this is for
- UK sellers adding OnBuy as an additional sales channel
- International sellers preparing to sell to UK customers via OnBuy
- Sellers who need catalog matching and listing management handled carefully
- Teams that want order and performance routines kept consistent across channels
