ERSG was successfully granted an AUG labour leasing licence in July 2013. This acquisition enables ERSG to work closely with key clients in Germany on leasing labour to the German workforce. Many clients are reluctant to deal with recruitment companies that do not hold an AUG licence as without one they may become liable for any tax or social security that is left unsettled. Following this achievement, our German payroll entity was established allowing us to ensure full tax compliance.
