Sønderup I/S – your secure partner for implementation of LessorLøn. 

Sønderup I/S is an audit firm with a payroll department of more than 20 highly skilled payroll consultants with many years of payroll experience in LessorLøn. To us, it is not only about implementing a new payroll system. It is all about your business and your needs. We analyse your current payroll set-up to ensure you get the right solution, and often, this procedure also reveals other processes to be optimised. 

​

We take you safely through the implementation and help you get started using your new payroll system. To us, this is a mutual process that you become an active part of. Apart from implementation of LessorLøn, we have extensive experience in day-to-day payroll administration as we operate more than 150 clients every month. This means that we offer fixed payroll support contracts as well as payroll outsourcing. In order to clear expectations of our cooperation from the beginning, we have a non-committal meeting to analyse your needs, and then we will send you our proposal.
