Our performance specification

Mercer – Your Reliable Payroll Partner

In a company, payroll is the sum of all financial records of salaries for an employee (wages, bonuses and deductions). In accounting, payroll refers to the amount paid to employees for services they provided during a certain period of time. Proper payroll management plays a major role. However, the collection, management and documentation of various data is very complex and should be done by an experienced expert to avoid mistakes.

The Mercer Payroll services  

Mercer offers all relevant services for the optimal management of your payroll. After you’ve sent the relevant input (gross salaries, bonuses and expenses, new joiners and leavers, changes of personal data), we calculate and create the monthly pay-slip for each employee. Common deductions (social security, tax at source, etc.) as well as the complex deductions of the occupational benefits scheme are included automatically. Furthermore we prepare the standard payment file for your financial institute, monthly reports for statutory insurances as well as an interface file for your General Ledger. For your HR department we provide reports for communication with Swiss cantons (tax at source) and your employees will receive an annual salary certificate.
