About contract management expertise centre CM Partners

CM Partners delivers a complete range of service with which organisations can handle the setup, professionalisation and implementation of contract management. An important principle in this is the contract management method developed by CM Partners: CATS CM®

CM Partners was established in 2005 by Gert-Jan Vlasveld and the late Jan van Beckum. In the 90s they were the founding fathers of the field of contract management. As a pioneer in the field, CM Partners grew into a leading consultancy, training and temporary placement agency.


Organisations no longer do everything themselves, but increasingly enter into structural partnerships. We believe that partnerships can always be improved. That’s why we are concerned with the way in which organisations deal with contract and supplier management. This allows us to help them get the most out of their contracts.


By sharing our knowledge and insights regarding contract management, we make organisations and colleagues aware of the possibilities in the field with the unique CATS CM® approach. This allows them to make partnerships with other parties more effective, cheaper and more pleasant.


We develop training courses with which organisations can train their employees to become skilled contract managers or retrain specific knowledge. Additionally, we advise organisations on the setup and implementation of professional contract management and support them in the search for interim contract managers.
