To add a customer to Fiitfu, simply click on the Purple Cross on the top Right of your Fiitfu Screen (You can also go to the Contacts Tab and choose the Green I Want To Button)
Now click on Add Contact.
You can now add your new client into Fiitfu. Please note the follow ups checked off on the bottom left hand corner will automatically populate this client's account. If you would like to take these off, simply uncheck them.
