Repair Invoice Audit: Parts, Labour Hours and Estimates
Check a mechanic's or repairer's invoice against the quote.
The Open buttons send the prompt text as currently shown below to that site only when you click. Fill in the placeholders first.
Audit my repair invoice. The written estimate: [ESTIMATE]. The final invoice: [FINAL_INVOICE]. What I authorised and when: [AUTHORISATION_RECORD]. The fault and what I asked them to fix: [FAULT_DESCRIPTION]. Compare line by line: parts, quantities, unit prices, labour hours, hourly rate, shop fees, environmental or disposal fees, taxes and discounts. Create a table with Estimate, Invoice, Difference, Authorised by me (yes, no, unclear), and Question. Calculate totals and show the arithmetic. Flag work or parts not on the estimate, labour times that look long compared with the estimate, parts charged twice, and fees not mentioned earlier. Suggest what to ask for (old parts, diagnostic report, photos, the warranty terms). Draft a polite query and, for items that were not authorised, a request for an adjustment. Do not comment on safety or the mechanical merits; ask for explanations. This is not legal advice. Name no rule I did not supply. Use [JURISDICTION] and [RELEVANT_LAW_OR_POLICY_IF_KNOWN] as given. Point me to a consumer agency. Threaten nothing beyond lawful steps.
