What happens if I don’t close the software but use other programs in the meantime?

If the software is not used for more than 1 hour, the calculation credit will not be debited. You only pay for actual use.

How is the usage time calculated?

You pay by the minute - that is, in real time. The debiting of the account balance takes place at the beginning of each hour. When the application is closed, the remaining unused minutes are tracked. These remaining minutes are deducted the next time the program is started. So you pay per minute that you use the application.


Software from competitors costs more than 4000 euro per year. Why is this lower at Struct4U?

By mainly working efficiently and using modern programming techniques (C# .NET). Our overhead costs are low. We are happy to give this advantage to you.

How will price increases be handled?

The cost of the software is increased annually by the European inflation level.

Are all modules paid from a bundle?

All our programs and future developments use the same analysis credit. It is possible to create multiple users, each with a separate calculation credit.

Do I have to pay for support? And for new versions?

You are always entitled to free support and assistance. New updates are included in the price and you can use them immediately. The program automatically notifies you when there is a new update.
