Many users of Mac-HaBu, Win-HaBu and Lin-HaBu asked us for a program to write invoices for services of a rental object (Apartments, Offices …). It seems that there is no application for this job, which works as flexible as our programs (e.g. cross platform). This was the reason; we decided to develop a new application.

xNeKo, Mac-NeKo, WinNeKo, Win-NeKo and Lin-NeKo are developed as independent applications. They can be used for rental objects. But they also work for objects, where only the service must be paid. Who need also an accounting program, can use our accounting program. Between both programs exists an interface, which makes it easy to transfer data.

During the development, we used the concepts of our accounting program. Beside the simple and intuitive operation, a high flexibility is extremely important. Older objects, different contracts or additional changes can make the calculation very complex. Therefore, a program must be flexible and expandable, also during the live cycle.

With the existing examples and the wizard you are able to install it very easy. Nevertheless, you are able to expand the calculations for more complex objects. With this feature, you are able to create invoices for almost all objects.

Through the high scalability (calculations, accounts...), an optimal protection of your investment is guaranteed. Of course, we also offer updates (usually free) regularly with new features.

What's new?

The following list shows the most important new features of version 19.3:

We also corrected all known errors and optimized the usage.
