A revised estimate should make additions and changes visible. Keep the original scope distinguishable from newly proposed work.
What to verify
Which line items changed? What prompted the revision? What review or authorization is still needed for the additional scope?
Write the answer beside its supporting document, date, and source. Separate an observed fact from a question that still needs confirmation. If two records disagree, preserve both and ask the responsible organization to identify the applicable version.
Worked example
A fictional shop identifies another item after inspection. The owner retains both estimates and asks the administrator to address the added work explicitly.
The example is fictional and illustrates recordkeeping, not a promised claim result. Substitute the facts from your own transaction; do not change a date or description merely to make it fit a preferred outcome.
A practical next step
Do not assume the earlier response answers a later, different estimate.
Send one focused request through the verified contact route shown in your paperwork. Keep the response with the original question. Mark the item resolved only when the specific discrepancy or missing information has been addressed.
Scope and source
This checklist does not determine coverage, interpret state law, or replace the agreement applicable to your vehicle. For general background, see the FTC guide to auto warranties and service contracts. Coverage conclusions require the actual terms and relevant facts.
