We do about the same thing, but we store absolute byte counts, relative
byte counts from the last measurement, and figure the kb/s; we also store
AdminStatus and OperStatus for SLA purposes.

Exactly, tough. If they use the bandwidth, then they should pay for the
bandwidth.


Depending on which switch you're using, you can also poll the switch for broadcast and multicast on the port and subtract that from the total so you don't bill for that.
