DIGITAL - making it simple

myGKK Portal

Paper was yesterday. The myGKK Portal is a software that was developed as a service for our clients; it enables easy and efficient digital collaboration between our firm and our clients, while also offering maximum security.

Sensitive documents?

They can be exchanged through the portal - easily and securely.

Out of the office?

No problem! You can access the documents regardless of time or location, using your desktop, tablet or smartphone. Uploaded files can be shared with individuals or a selected team. Joint editing in real time also facilitates collaboration.

  • Requirement lists with integrated processing status for a better overview of which information and documents are still required for the preparation of annual financial statements, audits, tax returns etc.
  • Analyses (annual reports, tax returns, assessments, payroll and financial accounting analyses).
