Payroll Administration means tiresome and ever changing activities, i.e., applying employment laws, monitoring local requirements, preparing contracts and maintaining employee records. With Leinonen on your side you don’t need to, we will do it for you.


Every company must take care of its business transactions, but local authorities often require specific procedures on certain terms. Your local Leinonen office is happy to take over all of these tiresome and time-consuming operations.

General Administration services at Leinonen make the business more convenient for you to manage. Upon request we can represent you in front of the authorities, archive accounting materials and provide a legal mail address or post handling service.
