Switch to CustomerConnect


In this initial phase, we conduct a thorough analysis of your communication landscape. We identify strengths and any shortcomings to ensure that our CustomerConnect solution seamlessly aligns with your needs.

This includes evaluating your current digital and physical customer communication channels to identify and address any possible "non-fits".


Proof of concept

We develop a customised proof of concept for a predefined use case.

This allows us to demonstrate the effectiveness of CustomerConnect and provides you with insight into its potential benefits. The goal is to instil confidence in the power of our solution and how it can be applied within your organisation.



A detailed strategy and architecture are drafted, including clearly defined milestones and mitigating measures.

This ensures a streamlined and risk-conscious implementation later on. We collaborate closely with your team to ensure a smooth transition to CustomerConnect without disrupting business operations.


Deploy and configure

We launch your new tool and ensure that all settings fit seamlessly.

We provide comprehensive training and workshops to teach your team how to independently configure and manage communication flows.


Onderhoud en beheer

After the successful implementation of CustomerConnect, we remain involved in the maintenance and management of the solution.

Our dedicated service desk is available 24/7 to provide support and address any questions or issues. This ensures the continuity and optimisation of your customer communication processes.
