The Company
Founded in 2015, ExpenseIn set out to make expense management easier and less frustrating, replacing time-consuming, paper-based processes with a smarter, faster solution. As we grew, we introduced new modules like invoice management, carbon reporting, and volunteer expense claims - all designed to save businesses time and hassle.
Today, we help companies in over 50 countries process more than a million expenses every month. In January 2025, we were acquired by AccountsIQ to bring even more value to finance teams. Together with the AIQ team, we continue to innovate and scale, helping businesses take control of their finances with smarter, more connected solutions.
