Actually, netflow works quite well for billing.  It's used by lots of
service providers for exactly that reason.  CENIC <http://www.cenic.org>
has been using netflow for billing for many years.  There are a few slides
from a 2002 talk here:

No idea where this comes from.  Sounds like a broken deployment...
