A tag is an identifier, namely, a keyword, that you can add to a client’s profile in order to organize or sort your clients.
To add a tag:
1) Go to 'Clients' tab and open client profile.
2) Under 'Tags' menu, type in your new tag (or select an existing one) and click '+' button.
3. Click 'Update'.
When making a booking, instead of entering client's first/last name, you can simply enter a tag and all linked clients will appear.
