With the blue office^® software, we have perfect organization. The address management is very clear. We can find all documents under the respective customer address and can see what we have already done at any time. It is a great advantage that the conditions can be stored at the customer address and do not have to be re-entered each time. The article structure is also ideal for us. And if I ever get stuck, I can simply call the Sieber IT team and they will help us competently.
