How much do your services cost?
It all depends on your project! We'll estimate your project and make you an all-inclusive offer for its realization. A website, for example, can cost between CHF 5,000 and CHF 100,000 (or even more), depending on the degree of complexity and functionality required. Contact us for a tailor-made estimate!
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.
