The world's open source lending platform

Corefin is the world's first open source lending platform. It allows you to deeply customize this software for your company's needs. It uses the Actual/365 method for calculating interest. See information from the CFPB.

Built by the engineers who built Square's first Consumer Lending product (Afterpay's Pay Monthly).
