The internet is really nice but put not your trust in it when FedGov comes calling. Or even State Gov for that matter.
Smiling at them and asking exactly what record they would like to see and then bringing them the folders one at a time can result in you passing the audit.
Let them into your electronic records and they are going to go fishing, no matter what the warrant says. And you did something wrong. Absolutely guarantee it. There is no way you can follow every single rule because what did not apply to you last year will apply to you this year for... reasons.
Not to mention the regulations that contradict each other.
I liked the old ways fine
