Cooling billing is a matter of trust

1. In times of high service charges and energy prices, apartment owners and tenants pay close attention     to the so-called "second rent". They expect a fair and transparent cooling billing.

2. Landlords and property managers want to allocate the incurred cooling costs of their buildings      smoothly and with no disputes about the so-called second rent.

3. Ontime billing and collection must be error free with no hassle of delays.

4. Efficient credit control procedures and tools insure full transparency.
