Connect OnBuy to eBay

Automatically connect OnBuy and eBay using a multichannel integration. Cross-list, sync, and manage your products across both platforms from a single platform.

Get started

Is OnBuy the same as eBay?

No — OnBuy and eBay are two completely separate marketplaces. And that’s exactly why connecting them is a smart move.

OnBuy was launched in 2016 as a UK-based marketplace focused on creating a fair and transparent environment for retailers and buyers, and unlike many platforms, it doesn’t compete with its own sellers. eBay has been around since 1995 and boasts one of the largest global buyer bases in the world.

Different audiences, different fee structures, different opportunities. Selling on both means you cover more ground, and with the right integration, managing two channels is no harder than managing one.

A rapidly growing marketplace

According to recent reports, OnBuy has been expanding rapidly across Europe, now live in over 20 countries and growing its seller and customer base at a significant pace.

Joining now means lower competition and a real first-mover advantage.

A worldwide eBay audience

eBay remains one of the most established global marketplaces, with hundreds of millions of active buyers.

Listing on eBay alongside OnBuy means your products get maximum exposure across different buyer segments.

Higher margins on both channels

OnBuy doesn’t compete with its retailers or hold its own inventory, which means no race to the bottom against the platform itself.

Combined with eBay’s volume, you get the best of both: reach and profitability.

Multichannel challenges

Selling on multiple channels has many strategic advantages, however, increasing the number of channels always implies an increase of complexity.

Without multichannel integration

Listing creation: you need to manually recreate every product listing on each channel from scratch.
Stock adjustment: every sale requires a manual quantity update on both platforms, opening the door to overselling.
Price differentiation: OnBuy and eBay have different fee structures, meaning your pricing strategy needs to adapt, manually.
Content management: each platform has its own listing requirements and best practices. Keeping content aligned is a constant effort.

With Nembol integration

Listing creation: bulk-import your OnBuy catalogue to eBay (or vice versa) in just a few clicks.
Stock adjustment: Nembol automatically syncs inventory across both channels every time a sale comes in.
Price differentiation: Nembol’s pricing rules let you apply channel-specific markups or discounts to offset fees automatically.
Content management: edit listings centrally in Nembol and push updates to both channels at once.
