Thanks but those apps that you suggest simply trigger multiple invoices inShopify to split payments. I want to know which actual 'but now pay later'services e.g. Klarna, are compatible with Shopify UK stores?

I see that Shopify's Shop Pay Instalments is not available for UK stores. Can anyone suggest an easy (and affordable) way to offer my customers the ability to spread payments when buying larger ticket items in my UK Shopify store? Thanks
