Splitit

Splitit is a credit card installment platform that enables merchants to offer shoppers the ability to split existing credit card purchases into monthly installments without requiring new credit applications, additional interest charges, or third-party redirects. The platform operates directly on shoppers' existing credit cards, leveraging available credit to create installment plans while merchants receive full payment upfront. Splitit provides REST APIs for installment plan creation, eligibility checking, refunds, chargebacks, and merchant onboarding, along with plugins for major e-commerce platforms.
