If, for example, you have an employee working in the field who does not need access to bexio but you want to include them on your invoices as a seller or contact person, you need a user for this.
So you do not have to set up an additional license and a fully fledged account with login, you have the option of setting up a contact person without login that doesn't need licenses and is free of charge.
You can add contact persons without login under "Settings - Plans / add-ons / users - Users".
On the right side you will find the button "new contact person"
You can then define the first name, last name and an e-mail address for the contact person and save the contact person without login.
