Select New Item.
In the Department field select Service. In the Category field select Service.
In the Name field enter Tip. In the Item # allow Juvonno to auto generate the number or enter a custom number.
In the Retail field leave it at $0.00 to allow you to enter the amount of the tip when creating the Quick Invoice.
Check out.
Enter the type of payment for the tip and complete the invoice process.
