Creating Listings on OnBuy

So you're considering becoming an OnBuy seller – or perhaps you've already signed up? Either way, you're probably wondering where to begin. By creating your listings, of course! Luckily, we've made the process really simple and straightforward.

OnBuy uses a catalogue system, so multiple sellers may sell the same product. This gives customers less clutter to browse through with the added bonus of simple seller comparison – they can easily compare prices, reviews and delivery options before buying.

However, there are exceptions! Certain categories and products in used condition don't require a barcode and won't be part of the catalogue system, e.g. live plants or collectables. Instead, you'll create individual products for each listing.

Which Categories Require Barcodes?

When listing products on OnBuy, most departments will require a barcode – either EAN, UPC or ISBN – which helps us match products and ensure we can efficiently market yours. However, there are some global exceptions:

Department Is Barcode Required?
Arts & Antiques No
Handmade & Custom Items No
Collectibles No

Additionally, within some of OnBuy's departments you'll find categories which don't require barcodes, e.g. the custom-made categories in Furniture and Jewellery. If you have any questions, contact the Seller Support Team through your Seller Control Panel – they'll be happy to guide you.


You can add your products to OnBuy in two easy ways: manually, through your Seller Control Panel, or as a one-off import using a CSV or XML file. Our Seller Support Team are on hand to help you with this and can even provide you with a template if needed.

You'll be able to update your price and stock, manage your orders and trigger dispatch notifications from your Seller Control Panel, either via the OnBuy API or a CSV. Additionally, we support a range of integrations which you can use to send your product information directly to us.
