At first I found it difficult to install the program at all. Constantly came error messages. The reason: you must enable JavaScripts what my browser at first but strictly refused (security issues). Was only taken as this hurdle, the program ran.
It is quite easy to use and can be explained in most cases by itself. Everything is in there, I do not use because I lot (so and so things like storage) do not need here. For me it is perfect now to have everything in one place, invoices, contracts, correspondence, etc. The program is easy. Only the templates for letterhead I find not so great, but I can live with it.
Conclusion: A good all-round package for small offices and freelancers.
However, one should take into account when purchasing the follow-up costs. Because if you have once entered all the data, you will want to use the program in the following years.
