Quick checklist

  • Do not wait until the audit notice to test portal access.
  • Do not treat vendor enrollment as a complete audit file.
  • Do not mix driver and vehicle records in one folder.
  • Do not edit old records without preserving source records.
  • Do not ignore former drivers and inactive units in the requested period.

Why this matters

Most audit mistakes are ordinary workflow mistakes. They are fixable when the carrier knows where to look.

What to prepare

Area Records to gather
Mistake examples
  • DQ file has license copy but no application
  • Maintenance invoice lacks unit number
  • ELD export has unassigned driving not reviewed
  • Drug testing records exist only with the TPA
  • Insurance certificate has old business details
Fix pattern
  • Find the source record
  • Save the corrected or missing document
  • Write a short note when needed
  • Update the routine that caused the gap

Common gaps

  • Portal access belongs to a former employee.
  • The carrier reviews active drivers only.
  • Paper receipts are not scanned.
  • Corrective actions are discussed but not assigned.

Before / During / After audit

Before

  • Run a mock audit using one driver and one unit.
  • Fix naming and folder issues before collecting all files.

During

  • Keep explanations tied to documents.
  • Use the missing-items log instead of scattered notes.

After

  • Turn each mistake into a checklist item.
  • Schedule monthly spot checks.
