Investment worth $25m by a consortium led by Warburg Pincus in PT Achilles Advanced Systems (dba OnlinePajak), the largest provider of tax compliance solutions in Indonesia which aims to help companies to reduce their administrative burden through seamless tax management. "OnlinePajak has built a market-leading technology platform to provide Indonesian taxpayers with a fast and user-friendly end-to-end solution to prepare, pay, and file their taxes. We have been strongly impressed by the virality of the business and we believe that the company has tremendous growth potential – not only in helping businesses across Indonesia to operate much more efficiently but also in playing a key part in realizing the Indonesian government’s vision to broaden the country’s tax base," said Jeffrey Perlman, Head of Southeast Asia from Warburg Pincus.
