Buy now pay later (BNPL) player Laybuy has launched an app, enabling customers in the UK to make payments in six instalments at 5,000 retail brands.

App users can make the instalment payments at zero interest at Amazon, eBay, Asos and Nike, among others.

Laybuy’s app has a built-in ‘shop directory’, which shoppers can visit to choose the retailer they want to shop with.

The retailer’s website will then load up as normal within the Laybuy app.

While making payments, users’ details will be automatically generated enabling them to pay in instalments.

This development comes shortly after the firm’s digital BNPL card launch in the UK, enabling customers to use Laybuy for contactless payment in-store.

Launched through a tie-up with Mastercard, the card can be loaded into users’ digital wallets.

Laybuy managing director and co-founder Gary Rohloff said: “Today’s launch is a significant step towards Laybuy’s goal of making Laybuy available everywhere.

“Not all shops accept BNPL or often it’s a different provider. This is a real game changer and means Laybuy will soon be available in the UK at more than 5000 brands.”

Laybuy started in New Zealand and launched in the UK through an alliance with Footasylum.

Earlier this year, the firm completed $25.7m (A$35m) placement from new and existing institutional investors to accelerate growth in the UK.

The BNPL market is a booming sector, with several players grappling for space.

Earlier this month, Square agreed to acquire Australian BNPL fintech Afterpay in an all-stock deal valued at around $29bn (A$39bn).

The San Francisco-based digital payments firm plans to integrate Afterpay into its existing Seller and Cash App business units.

Also, recently, Citi Australia entered the BNPL space with the launch of its new offering, dubbed Spot. Buy Now Pay Later.

On the other hand, Apple recently joined forces with Affirm’s PayBright to launch a BNPL offering in Canada.
