- 01
Confirm the record identifies the agreed job, its current status and the person responsible for invoice review.
- 02
Compare the documented work with approved scope. Flag missing approval; do not assume a completed task creates permission to charge.
- 03
Trace issued parts, supplier documents, returns and existing invoice lines. Record differences as questions, not automatic additions.
- 04
Check that supporting notes describe work actually performed. Ask the responsible person to resolve missing or conflicting information.
- 05
Assign each open question an owner and next action. Move the record forward only under the shop's agreed review rules.
Keep the boundary clear.
This checklist does not establish customer liability, warranty coverage or vehicle safety. Fixed-price and warranty work may require a different billing treatment.
