Each module has a Help menu, from which you can select About INVOICES. This displays information about the INVOICES program version and the current license.
If you have a license that is based on time, the Valid until value in the dialog indicates when the license expires.
If you have a volume-based license, the Capacity value in the dialog tells you how many total invoices can be processed. In the System info dialog mentioned below, you can also see how much of the available capacity that has been used.
System info displays information about your system.
