Prefer one fixed person who does the work?
Do you mainly call Group S to pass on hours worked, have a Dimona filed or have a payslip checked? It can work differently. At Business Centrum you do not do that work yourself in a portal:
- You send the hours worked, by email or form. We enter them and call you if something is not right.
- We file the Dimonas, for permanent staff, students and flexi-jobbers.
- You call or email your fixed contact directly, who knows your company and your joint committee.
- Acerta remains the recognised secretariat behind it, under number 250. It files the returns and collects the contributions.
How Group S compares with the other secretariats on the official list is covered in the largest social secretariats in Belgium. How the roles are divided with Acerta is explained in Acerta or Business Centrum.
Switching from Group S: when can you?
A switch always takes effect at the start of a quarter, and your contract with Group S determines how far in advance you give notice. So plan backwards from the date on which you want to start. How to calculate that date is explained in notice period social secretariat. All the steps of the transfer are in changing social secretariat.
