System variables are used for replacing items such as client's name, address, tariff etc. with real client values into emails, SMS, invoices, reminders, contracts etc. This way you will be able to use one template to create many personalized messages, emails, and more. The template may be used for a certain client group/all clients later.
System variables are divided into categories, e.g. Client, Internet, Invoices etc., and are being pendingly added, hence no overview can be listed here. You will be able to see complete list of the variables every time you see List of system variables.
Most commonly used for: Settings Contracts My Templates, Settings Other Email templates / SMS templates, Invoicing Settings Templates Reminders
You may also add your own variables into the system.
