Intro - former utility employee

I'd read that in a heartbeat. Understanding the root cause of errors makes you a better auditor because you know where to look. — Sarah M

Please do write that guide, Floyd. I'll pin it in the Audit Methodology topic if you do. This kind of knowledge sharing is exactly what AAUBA is for. — Randy D

Count me in too. Knowing HOW the errors get made helps predict WHERE they'll show up. That's a huge efficiency gain when you're reviewing bills. — Marcus T

All right, you've convinced me. I'll start working on a billing system overview document. Give me a few weeks. Thanks for the encouragement everyone — and thanks for welcoming me back for this second intro.

Floyd, a follow-up on the multiplier errors. When one of those installs was caught within a few months, did the utility rebill the customer for the whole period, or was there a cap on how far back an underbilling could be collected? I have seen tariffs that limit back-billing on the utility side while refunds to the customer reach further, and I am curious how the billing department handled that internally.
