It’s beginning to look like a busy holiday shopping season at ChannelAdvisor (NYSE: ECOM).

A large online ecommerce marketplace in the U.K. is the latest firm to sign on with the Morrisville-based company to simplify selling by other retailers on these bigger sites.

On Friday, ChannelAdvisor announced a partnership with Tesco, thus becoming the first solution provider to work with the U.K. site.

Over the last two weeks, ChannelAdvisor also added Best Buy and a major online marketplace servicing Latin America as partners.

ChannelAdvisor customers can now offer their inventory through Tesco from listing to order management. Its software enables customers to link with numerous marketplaces simultaneously with one feed while still meeting requirements of each for how items are listed.

“We are thrilled to be working with a strategic partner like ChannelAdvisor,” said Ian Caminsky, Partnership and Business Development Director at Tesco. “Through ChannelAdvisor, retailers have a simplified integration process with our marketplace, giving them more time to focus on providing great range and customer service. As a result, we can offer our customers more products at great value, with the added convenience of being able to pick up orders from our stores via Click & Collect. Finally, customers ordering from retailers on the Tesco marketplace will continue to earn Clubcard points, but on a much wider selection of brands and products than ever before.”
