How the review labels findings

Fair Bill Analyzer reviews an itemized legal invoice as a record of work. Every result names the lines it is based on, so you can check it yourself. This page explains each label on the results screen, the exact condition that produces it, and what the review cannot determine.

Proven: "Arithmetic that does not add"

Shown when a line's hours multiplied by its rate differs from the amount shown for that line by more than one cent, or when the line amounts do not add up to the invoice's stated total. It is a record-level inconsistency in the visible figures. It does not explain why the figures differ; a discount, credit, rounding rule, or correction may account for it.

Proven: "Duplicate time, same task, no explanation"

Shown when two testable lines share the same timekeeper, description, hours, and rate. The pattern merits a question. It does not establish that the same work was billed twice: one line may be a correction, a separate event described the same way, or work on a different matter.

Untestable

Shown when an entry lists three or more tasks separated by semicolons, or when the whole entry is a broad phrase such as "further work on matter" or "various emails". The review counts these lines instead of guessing a dollar figure. An untestable entry is not proof that the work did not happen; the detail may exist in records the invoice does not show.

Reference

Shown when an entry leads with a clerical-sounding task (for example scanning, photocopying, calendaring, or transmitting documents) and is billed above the invoice's own lowest listed rate. It is a comparison for context, never a finding that the rate charged was improper, and it is never added to the Proven total.

Assessed (paid tier)

AI-written observations about the redacted line text, each citing the lines it refers to and labelled "Assessed, not proven". They are produced only if you approve sending redacted line text, and they never override or restate a Proven result.

What no label means

If the review finds no checkable arithmetic mismatch or duplicate-looking pattern, that does not establish that every charge is appropriate. Some questions require the fee agreement, supporting records, or professional review.
