The SaaS model has truly revolutionized the way software is being used. Convenient, hosted on the now cloud, without the need for IT or hardware and so many more advantages. So what is cloud-based billing? A recent piece by Gigaom helps explain why cloud billing is beneficial and how it helps vendors move all aspects of a paper-based system to the cloud. But isn’t that old technology? Isn’t that about generating a PDF file and sending it to your customers instead of a printed invoice? Perhaps not. Perhaps this is about a billing system that works for the SaaS software, charges customers online and they can pay online. Perfect! This is turning out to be good.
