Contacts can be anyone within our without an account. A contact can also be a team member. If you are going to be checking in/out products to people, they will need to be in the system. If they are not users or part of an account, you can still add them as a contact.
Click the ADD button (bottom right corner, second button from the left). All fields with a red asterisk must be filled in. When done click the CREATE button (bottom left, first button from the left). The CREATE button then changes to a SAVE button. Click SAVE.
