How we work

01

Development and funding

We usually take part by bringing in software or capital, along with our development know-how.

02

Strategic guidance

A sparring partner for the big decisions, with almost forty years of building companies behind it.

03

Finance and HR

If a company wants it, Isatis Office Support takes care of the books and the people side, so the team can focus on the work. Never an obligation.

04

Shared ownership

Whoever brings the idea becomes a co-shareholder. We stay an involved and active shareholder.

“Thanks in part to companies like Isatis Group, Nijmegen is increasingly seen as a city of IT and innovation.”

The team that visits our companies

Isatis Office Support grew out of Isatis Group. Companies in the family can call on it for finance and HR: an offer, not an obligation.

Its HR people visit the companies, get to know the teams and help with everything that comes with people: from advice and payroll to hiring, growth and saying goodbye.

  • Dyandra Evers Dyandra Evers Director, Isatis Office Support
  • Yolanda Groeneveld Yolanda Groeneveld Senior HR Professional
  • Alain van den Bos Alain van den Bos Junior HR Professional

At Isatis Office Support, everything is about taking work off your hands. We handle HR and payroll from A to Z, with the knowledge, the software and the people to do it well.

  • Every employee paid correctly and on time. We process changes, file the payroll tax returns, send digital payslips and handle pensions. Including payment files, payroll journal entries and WBSO. Permanent staff and on-call workers alike.

  • From starters and leavers to employment contracts, leave and absence coordination. We keep personnel files up to date, watch retention periods and make sure the right documents are in the right place. Non-disclosure agreements, certificates of conduct, references: we take care of it.

  • A difficult conversation with an employee, questions about dismissal, support during pregnancy or reintegration: our HR advisers are there. For managers and for employees themselves.

  • We work with AFAS HRM and know it well, from daily use to setting it up. Employee and Manager Self Service, custom workflows, digital files: we set up the software so your processes fit it. In our own AFAS environment or yours.
