You can be pretty sure that there are probably a lot of billing
systems based loosely around the tools mentioned here, and that in
their particular environments they are robust enough to be successful.
If you go down this route, or a similar route, you need to remember
that you MUST update the default RRD storage behaviours so that the
most granular data is not aggregated until four or five months after
the billing month, otherwise you will find that the averaging causes
different results to fall out of your scripts when you look into
customer queries on their bill !
