This software I have acquired in order to make a professional utility billing for an apartment building can. For this you need a really basic course (I and the software) in order to see through, at least in some areas can since the whole is built up and complicates more than confused. The result was that I have as yet made my billing in Excel without WISO landlords who might not look as nice, but is at least accurate, complete and comprehensible.
Saves you money and stay away, here there certainly something better it is in the market which may not WISO !!
