Emarald has an accounting package, but for a very stiff price. You could
alternatively check out www.omegasoftware.com and read about ISP Manager (NT
Billing package). It is in beta at the moment but offers some very useful
features at a very reasonable price. There are others, Platypus
(www.boardtown.com), ISP Billing and a scant few more, but none that I'm
aware of that interfaces so closely with NT like ISP Manager.
