Having worked with numerous online retailers of all sizes since our launch in 2016, we know that every business operates differently. That’s why we wanted to give our sellers more choice when it comes to listing products in our catalogue.

Top tips for selling on OnBuy


  • Set the main image on your listing as a photo of the product on a white background without packaging to ensure it’s eligible for external marketing – this will increase the visibility of your product to an even wider audience of shoppers!
  • Use high-quality images to present your product in the most attractive way to buyers
  • Avoid using images containing other products not included in the listing as this can mislead customers

Product descriptions

  • OnBuy works on a catalogue system where multiple sellers can list on a single product, so avoid any references to shipping, seller-specific freebies and warranties
  • Take extra care with quantities, measurements and volumes to ensure there’ll be no surprises for customers upon delivery!

Product details

  • You can claim your brand through the OnBuy Brand Ownership feature to prevent other sellers from listing on your products – just fill out a form through the Seller Control Panel when you’re signed up for our brilliant Seller Management team to review!
  • You’ll need to list your products with a barcode (our team can assist with this) unless you’re listing in an exempt category, such as jewellery

  • Should you have any issues with customers, our Seller Support team are on hand to advise on the best way to handle any situations.

I have been selling on OnBuy for a while now and have had some success. My only gripe is that if another seller undercuts your price by 1p, then your offering seems to disappear. Having been seriously affected by eBay's continued race to the bottom on price (and to hell with any consideration for excellent service, warranties, etc), I am concerned that OnBuy will follow this trend when the Chinese invade, as they surely will.

BFT • 15th September 2020 •

Seem to be a lot of drop shippers on the platform, many Chinese listings via dropshipping through I suspect Amazon.

ifellow • 15th September 2020 •

Indeed the exclusive brand I sell is for sale onbuy at an extortionate rate, Onbuy should kick out all the dropshippers.

ifellow • 15th September 2020 •

Hi BFT, thank you for your comment. We’re pleased to hear you’ve had success with us - we look forward to expanding on your success as we begin launching globally very soon! We appreciate your feedback regarding multiple sellers on a listing. We make available listings easy to find for buyers: unlike other marketplaces where you have to navigate to a separate page, we have a table on the product page showing all listings. We have a link by the lead listing box so customers can easily view this table and compare seller reviews and delivery options (plus a specific link that shows near the lead listing box when faster delivery options are available), however we’re constantly evolving and enhancing our site so we’ll pass your feedback on to the team to see if we could improve in this area. Do get in touch with our support team or your account manager if you have any further feedback or we can answer any other questions - we’re always happy to help.

It is just another catalogue marketplace like the rest of them. Lowest price WINS. In our sector your 9% plus Paypal 2.9% plus a 30p which is actually a fair bit more expensive than eBay. The few things I listed were so badly described. However they seem fairly quick to actually change the listing which is good. I have said before the big advantage they are throwing your stuff around the web on all the price comparison sites, it does not do much in our sector because the high fees but would probably suit others. Don't use the multi channel extensions they provide however "nightmare" untested, broke my whole site (I did reach out Onbuy before you start the message has been left open for weeks now) I gave up. As others are saying YES China sellers have started to appear. We do need some other alternate platforms in the UK as we only have ebay and Amazon so there is little choice or competition.

SAM • 15th September 2020 •

Hi Sam, thanks for your comment. We mentioned this in another comment on this post but we aim to make it easy for buyers to browse all listings on a product - there’s a table on the product page that shows all listings and displays seller reviews and delivery times/costs. We have links to this table towards the top of the page so it’s even easier for buyers to find. As we’ve mentioned previously, several companies offer integrations into OnBuy and while we don’t build these ourselves, there is technical support available from the providers which you can utilise. Our support team are always on hand to help with any issues as well, and we appreciate you reaching out about the issue with this integration - we always welcome feedback about your experience using our platform and will offer assistance where we can. Our support team’s response time is usually one working day and often quicker than this. We’ve expanded our team recently to ensure we can keep providing this great service, however on occasions where an issue requires further investigation it may take the team longer to get back to you while they look into it, but they should keep you informed of this. We’re proud to provide a viable alternative marketplace for online retailers of all sizes, so thank you for recognising this. We’re gearing up for our global launch as well, which will put our sellers’ products in front of a worldwide audience - watch this space!

OnBuy • 16th September 2020 •

Been excellent for us this year on Onbuy, sales went through the roof and margins much better than on other sites, but we don't have as much competition as we do on ebay at the moment. However 2 things that wind me up, but are found on all market places, are these huge companies that just stock everything, but they have no knowledge of what they sell and the listings are clearly just grabbed from catalogues etc... The big issue is that they obviously automatically upload duplicates of their other sites and so the listing is riddled with 'special characters', typos and the such. They obviously never bother to check anything after the upload. To add insult to injury, and i would love to mention a name here, but i won't, some companies mark branded products as their own so you can not add to the listing. As they use the correct EAN it causes issue. I will give Onbuy full credit for being quick to address these issues, but it is time consuming when a company has done this to masses of listings. As for Chinese sellers and drop shippers. I have no idea what to do about them. It is very hard to prove when applying that they aren't in the UK if they provide a UK business address etc? I'm guessing that atleast they must be registered as a business, but still an issue. A few things i have really liked though.... The ability to add different shipping rates to different places in the UK on the same listing! Why oh why the likes of ebay can't work this out i don't know? It means i don't have to exclude locations because people don't read decriptions that tell them to contact us before purchase if in certain areas... so no email ping pong, extra invoices and cancelled sales. The holiday settings thing is great too, and i see ebay have finally woken up to this! So all in all, it may not be perfect, i doubt any market place will ever be, but it is good to see a new face on the block that is taking itself and its sellers seriously. We have certainly done very well out of it.

"How to sell on onBuy" ??? It must be hard going for them is they need the repetitive marketing on TB and other sites.

NorthCrystal • 16th September 2020 •

I would love to know if there are any plans in the pipeline for an integration with Visualsoft? I know on here there are the usual negative people who basically complain continuously about eBay and other platforms - and I too have frustrations, but at the end of the day we have the choice to be on them or not. It is like takeaways who complain about Just Eat, Hotels moan about - remember when these places didn't exist and you had to find a way to get business directly. We really do need positive thinking with what is going on in the world at the minute - especially if like me you sell to the Entertainment and Events industry.

Darren • 17th September 2020 •

I had never heard of onbuy but it does look really promising! Definitely a lot of drop shipping going on, however, but there is on Amazon and eBay also. Will have to keep an eye on these guys!
