Answer
Each active Lightning Payroll subscription — monthly or annual — includes two desktop installs (seats) for use on Windows or Mac computers. The desktop version does not automatically sync data between machines, but your payroll data can be easily transferred using one of our backup options, such as the Online Backups feature.
In addition to your two desktop seats, your subscription also includes access to the Lightning Payroll web and mobile app, which operates in the cloud and does not use up a desktop seat.
If a particular computer is only viewing the payroll data (and not editing it), a licence seat is not required. See here for more information about the three licence 'modes' available in the software.
If you need more than two desktop systems using Lightning Payroll at the same time, you can purchase additional subscriptions under the same account — each subscription will provide you with two more desktop seats (plus another web/mobile login).
