To make it short: This software runs more than 365 days. This is also on the package! Such packages are only useful if you have permanently against such use a program. The first time, it generally takes longer than by hand, as you have to enter everything. From the second year it is then but still brisk. (This is what we experience in the control software of Buhl)
My Schweiger parents helps the package to manage their tenants. They have quickly found in the menu structure cope. That I regard as positive times. It will be gradually as with other programs of Buhl (W iso). You can get anything from the monthly Abrechhung to annual accounts.
What we like, you have to be a specialist to make correct statements.
