School Transportation Invoice Audit Checklist

Identify the billing and contract records

• Record the vendor, invoice identifier, billing period, and applicable contract or amendment.
• Identify the approved rate basis, service type, and permitted billing conditions.
• Confirm who owns transportation review, contract interpretation, and the final payment decision.

Compare billed routes with available service evidence

• Match billed lines to district-approved routes, service dates, and available assignment records.
• Inspect cancellations, schedule changes, duplicate lines, and charges without supporting records.
• Check whether invoiced rates match the conditions the district independently verifies in its contract.

Document exceptions before a staff decision

• Capture the invoice line, contract reference, available service evidence, and reason for staff review.
• Separate missing evidence from a confirmed discrepancy. An incomplete record is not proof of overbilling.
• Record the reviewer, follow-up question, vendor response if applicable, and district-approved resolution.

Keep payment authority and implementation decisions with the district

Authorized staff decide whether any real invoice line is accepted, questioned, corrected, or escalated. The public sample demonstrates deterministic matching and staff-reviewed sample credit actions using fictional records only. Any district data, integration, security control, production workflow, or implementation must be separately scoped and verified.
