i gave up on per-customer interface accounting, didn't scale for me.

for a while, i had a BSD box in the middle of my network, and i used
ipfw rules (which worked both as counters for accounting, and as
ingress/egress filters).

we've since moved to cisco, and, well, now i have cache flow stats which
are parsed into customer subnets.

unfortuneately, i've practically had to install seperate interfaces for
the cache flow data, as it is a steady huge flow of data, especially
for sub-30 minute periods.
