In the Apartment Management System (AMS) there is a difference between what is defined as an "Apartment Type" and an "Apartment".
Apartment type: This describes the different categories / types of apartment that your property has to offer. For example: studio apartment, one bedroom apartment, two bedroom apartment and so on. You can create your own apartment type for each property that you are managing under the "Properties" section of the AMS.
Apartment: This is the physical apartment. You should add each unit which you have available by clicking on the "Add Apartment" button under the applicable apartment type.
