free modules

We offer you some of our modules free of charge.

Why do we offer you free modules? Our answer is simple. Your structural challenges are a great help in the development and expansion of our software. Your feedback is extremely valuable to us. And this is our way of thanking you for your suggestions and ideas. Consequently all free modules can be used without any binding contract or further costs.

These modules can be used free of charge.

fee-based modules

Not every task occurs daily. That's why we offer you two purchase options individually for each module.

For static calculations which only occur in certain projects we offer you the opportunity to rent our modules for 3 months. For your daily routine you can choose our yearly package.

You decide which solution is best for you. This way the adequate modules are always available. All modules are activated immediately after purchase.
