At Autohost, we care about making data-driven decisions. I know many companies say this, but we mean it. We have a lot of data, and we want to use it to make better decisions. One of the issues is related to understanding the differences between signed contracts and billed invoices, and how to predict revenue. We can't tell if we are on track to hit our revenue goals, because we don't know how much revenue we will get from our existing customers as product usage changes.
