There are three ways to do this:
The first option is to log in to our CloverCARE Portal, navigate to your License Keys section and click on the Extend Trial button. This request is then sent to our sales department for approval.
The second option is to contact our sales department directly via firstname.lastname@example.org. Please don't forget to include your company name and your license number.
The third option is shown in Designer, when your license has expired. A dialog window will pop-up and offer you an option to extend your license.
