Account Relationships

"Some of the stand alone objects that are drawn into a relationship with the Account are the customer, the address or parcel (for property-based bills such as tax or utility bills), the services or valuations being billed on the address or parcel, the permits associated with the address (if property-based) or the customer, and the licences that customer holds or that have been granted for the business. Utility billing applications will also have information about the meter and its reading route and sequence."
