In several responses and replies to me in emails, people have wanted to know basic import on the terms on which this blog is based. So I will now attempt to answer these questions in this post as well as future posts. So Billing will be first term that I will try to address.
The Wikipedia and several other places on the net provide the different definitions for billing.
Let me attempt the turn of explaining this to you in a simple sequence from the inception of a business to the action of billing for initiating the chain or cycle of activities which help in recognizing the revenue of this business.
Say there is a need for some service/product which an individual, a group of individuals or a more specifically say a company /organization requires. So in absolutely bare terms and though there are more factors to it but in the minimalistic sense when the need for this service permeates beyond a critical number of individuals then the chance arises for a market to be created for this service.
Now this critical number is never a fixed number, it just cannot be. This number is recognized as demand defining threshold. And this threshold is the trigger which makes people having the resources, plan and knowhow to kind of satisfy this demand start taking notice of this demand.
