DoorDash and fintech company Klarna are teaming up to offer customers the option of buying now and paying later on the food delivery app. Customers can choose to pay in full, in four installments, or defer payment to a more convenient time. This buy now, pay later service is becoming more common, with DoorDash's rival Grubhub and other companies offering similar options. The partnership comes as more Americans are hesitant to apply for traditional loans, with the buy now, pay later model gaining popularity during the pandemic. Klarna's expansion into everyday spending categories is seen as a milestone, although some providers have faced criticism for issues with disputed charges and fees.
