Why was the brake job labor flagged on invoice AF-2291?
You · just now
The rate exceeds your AFP Schedule B ceiling.

Amerit billed $185/hr × 6 hrs = $1,110. Your AFP contract caps this repair category at $90–$120/hr in your region. At the maximum allowed rate, that job should have cost $720.

Overcharge: $390. This is a disputable line item.
