It may not be the best solution, but I've been running nnstat with a
simple config that sums up the bytes to/from the given IP address into
each customers "bucket".  A perl script gathers the info from it's log. 
It's been running unmodified without problems for 2 years now.

nnstat makes use of the fact that ethernet is broadcast (it's pretty much
a sniffer) so the machine must be located where all the traffic will pass.
