Integrated International Payroll (iiPay) has developed a leading edge software to simplify payroll administration for global organisations. The proprietary payroll software calculates and integrates global payrolls in real-time across an entire organisation both simply and flexibly. Payrolls can therefore be processed, managed and controlled from one site, regardless of the size and geographical diversity of the organisation. The software is suited to complex payroll situations involving expatriates or temporary workers. In addition, iiPay is the majority owner of Celergo, a Chicago-based international payroll bureau service, which operates the iiPay platform.
