Whether you use trip sheets or an ELD to keep track of trips, if we audit your records for you, all of our work is guaranteed, so long as we have all records we require. If you ever receive an audit by a state agency and receive an assessment on any work we did, we will pay all penalties and interest associated with that assessment. We will also keep all records at our office so state audits can be conducted in-house whenever possible. This relieves you of having to make yourself available for registration and mileage/fuel tax audits. Reports we can provide through auditing include: Fuel breakdown by unit and state, mileage by unit and state, and fuel cost analysis.
