Subscription Period: Customers are asked to purchase the support subscription annually in advance. Invoice date will be the date the subscription starts and is payable on receipt.

Subscription Components: The subscription is calculated using three components:

1. Number of gateways and devices the customer wishes to include and the estimated time required to service these per annum.
2. Number of physical visits the customer requests per year, reflecting travel time.
3. Chosen service level: Classic or Pro. Opting for the Pro level doubles the care given to your devices.
