We make every effort to understand your needs, those of the users and the objectives of your project.

How do you bill for your working time?
Our offers usually include a flat fee, without any bad surprises. In the meantime we ensure a detailed follow-up of each project. This includes tracking time on each task. You can even ask us for detailed reports if you want.
Will I learn by working with you?
Yes! We share our knowledge with you throughout the collaboration. This allows you to understand the methodologies and the ins and outs even if it is not part of your area of expertise.
