How It All Started

Abacus was founded in 2013 by Omar, Ted, and Josh with a simple idea: when employees at your company incur expenses, you should be able to pay them back quickly. Abacus has been designed from the ground up to keep pace with the speed at which business now moves.

Replacing the expense report with a real time expense system, Abacus is helping businesses get money wherever it needs to go faster. By accounting for company spend at the expense level as it’s happening, Abacus keeps all company business systems in sync and offers the most dynamic reporting on the market. Our goal is to provide finance teams with tools and data that enable them to become a strategic pillar in their organization.
