The application is very simple to use. I will specify the answers to the questions to be asked in use as an explanation here.
3 steps to be done;
Step 1: Site's monthly invoice
Step 2: Entering flat information
3. Step: The last step is to calculate the invoice that the whole site has to pay with the "Calculate" button.

- Quick calculation by editing only the differences every month with the Update button
- Deletion of flats that have been entered more than once
- Sharing of calculated invoices (Whatsapp, Sms, E-mail ... etc)
- If there are flats that will not be included in the invoice on the site, the invoice of the flat you entered incompletely will be divided into other flats.
