Start with the evidence
Gather the original quote record, any revised versions, job evidence and final invoice. Identify which facts were confirmed at the time of each communication. Separate added scope, corrected information, a calculation error and an unexplained difference. Keep customer records private during the review.
A worked example
Fictional ledger: the original recorded amount is $180, a later documented scope revision is $30 and the final invoice is $220. The visible records explain $210, leaving $10 unresolved. The right response is to find the missing basis or correct the record, not label the whole $40 difference as a documented customer change.
Choose the next action
Assign each difference to evidence and a responsible person. Preserve the original values. If the issue concerns permitted charges, required disclosures or a dispute, use authoritative local guidance and appropriate professional review rather than a generic marketing article. Communicate only facts that the business can confirm.
Check whether it worked
Close the review when the records reconcile or an unresolved item has a clear escalation owner. Check whether the invoice itself needs correction through the approved process. Analyze recurring discrepancies for missing intake details, version confusion or arithmetic errors. Do not remove difficult records from marketing reports merely to improve the apparent average job value.
