Add pet parents as new clients either by creating their profile for them or by inviting them to create one themselves.
To add a client manually or to send an invite click on Clients > Add new client
To create a client profile without sending an Invite to the client, make sure the "Send invite link" checkbox is unchecked.
You may choose to send an Invite so your client can click the link in the email and sign up. In that case either leave the 'Send invite link' checked or click on 'Invite a client' button in top right.
Should you choose to fill out the client form and send the invite link, the client's sign up form will be pre-filled out.
