SAFE stands for Service and Administration Front End. It is a basic Web-based application that allows small companies to perform invoicing tasks, both one-off invoices and recurring services (subscriptions). Subscriptions can be entered with a price per month, per quarter, or per year. Invoice lines can be joined together by your company administrator into an invoice. That invoice can then be downloaded in PDF format, printed, and sent to the customer. SAFE is meant to allow non-techical people to work with the invoicing system, so simplicity is key.
