Line-by-line method

How to compare an auto repair estimate with the final invoice

Align lines by the work or part they describe, then compare description, quantity, unit amount, labor time or rate, tax, fee, and total. Keep unmatched items visible instead of forcing a match.

A practical comparison order

1. Keep each document as a separate dated version.
2. Confirm the vehicle and repair visit are the same.
3. Normalize obvious formatting differences without changing the original text.
4. Match confident line items and flag uncertain ones for review.
5. Compare any added or changed item with the approval records you saved.
6. Recalculate subtotals only as a check; do not overwrite document amounts.

Why source links matter

Text recognition and matching can be wrong. A useful comparison lets you reopen the page, image, or user-entered note behind every result. RepairGap keeps that source path with the finding.
