Steps
In the left-hand menu, click Address book.
In the top right, click New contact.
Choose the Contact type: Owner, Tenant, Guarantor or Service provider. The Create new contact form opens directly.
For a service provider only: select a role from the list or type a new one.
Select the contact's Legal form: Individual or Company.
Fill in the General information (first name, last name, email, phone, language…).
Fill in the address, depending on the contact type:
Owner: fill in the Address section.
Tenant: if their contact address is different from the unit's address, turn on the option to enter a different contact address, then fill it in.
Guarantor or Service provider: to add an address, turn on the option to add an address, then fill it in.
Click Save.
The contact then appears in your address book. You can then link them to a unit (for an owner) or to a contract (for a tenant or guarantor).
