# Auditor

> Is the outside party who says someone else's numbers can be relied on — and whose signature is the only thing that makes that worth anything.

## Scope

Written for external audit and assurance in a firm, and largely applies to internal audit too. It is a different occupation from accountant: an accountant produces the numbers and closes the period, an auditor is the outside party who tests them and signs. The tax practice is different again. Regulation matters more here than on most pages — who may sign, and what they are liable for, is set by law and differs by market.

## Tasks

### Sampling and testing

- Direction: Automating
- Basis: evidenced (verified records attached)
- Why: Sampling exists because testing everything was too expensive. Once testing everything becomes cheap, the sample loses its reason to exist — and full-population testing has been ordinary in large audits for a decade, well before anything called AI. What generative tools add is the ability to read the supporting document rather than only the ledger entry, which extends the same trend into the half that used to require eyes.
- What this does NOT establish: Says nothing about how audit hours are actually billed, and in many firms the hours freed here were absorbed into more testing rather than into fewer people. It also says nothing about smaller audits, where the tooling is often not bought at all.
- Records:

### Deciding where to look

- Direction: Still human-led
- Basis: evidenced (verified records attached)
- Why: Anomaly detection genuinely helps and finds things a person would miss. What it cannot do is know which unusual thing is worth pursuing in this business, this year, given this management's incentives — that requires a model of why someone would want to misstate, and the incentive lives outside the data.
- What this does NOT establish: A judgement about the nature of the work, not a measurement. It also does not claim auditors are good at this: missing the risk that mattered is the defining failure of this profession and there is a long public record of it.
- Records:
  - 2024-06-12 · Deployment · The US audit regulator found auditors mainly use technology-assisted analysis to identify and assess risks, and requires the auditor to investigate what such tools flag — https://flyvolo.ai/en/changes/ev-20240612-auditor-5 (source: https://assets.pcaobus.org/pcaob-dev/docs/default-source/rulemaking/docket-052/2024-007-adoptingrelease.pdf)

### Asking the question that gets a real answer

- Direction: Still human-led
- Basis: evidenced (verified records attached)
- Why: Evidence in an audit is not only documentary; a great deal of it is what someone does or does not say when asked directly. That is a live social act with a person who may have a reason to mislead, and the auditor's professional scepticism is exercised in the room, not in the file.
- What this does NOT establish: Nothing here measures how much of a modern audit is inquiry versus document testing, and in many engagements the inquiry is a formality completed by email. Where it is a formality, this task is not human-led — it is simply not being done.

### The file and the opinion

- Direction: Being augmented
- Basis: evidenced (verified records attached)
- Why: Working papers are structured, repetitive and heavily templated — close to the ideal case for generation, and this is where firms claim most of their time saving. The opinion itself is different in kind: its wording is regulated, and a modified opinion is a public act with consequences for the client that the person signing has to be willing to cause.
- What this does NOT establish: Nothing public measures documentation time saved in audit, and firm claims about it come from a party selling the transformation. What would settle it: a regulator's inspection findings on files prepared with these tools.

### Signing it

- Direction: Still human-led
- Basis: evidenced (verified records attached)
- Why: Not a difficulty claim. In every market that has a statutory audit, the law requires a licensed individual or firm to sign, and attaches liability to that signature. That is the whole product: an audit is valuable precisely because someone can be sued over it. Automation does not reach a position that exists in order to be liable.
- What this does NOT establish: It protects the signature, not the headcount behind it. A firm can sign the same number of opinions with fewer people, and the signature says nothing about how many juniors were needed to get there — which is the number most readers of this page actually care about.
- Records:
  - 2015-12-15 · Constraint · US audit regulator's rules require firms to disclose the name of the engagement partner on every public-company audit and give each partner an ID, after choosing disclosure over a partner signature — https://flyvolo.ai/en/changes/ev-20151215-auditor-4 (source: https://pcaobus.org/Rulemaking/Docket029/Release-2015-008.pdf)

### Owning what the machine drafted

- Direction: New task
- Basis: evidenced (verified records attached)
- Why: New work created by the tooling, and the failure mode is specific: generated professional text is most dangerous where it is most confident, because a fabricated citation looks exactly like a real one to a reviewer who is skimming. This site holds a record of a Big Four firm repaying part of a government fee after fabricated references and a misattributed court quotation were found in a report it had drafted with a generative tool.
- What this does NOT establish: That record is one consulting engagement at one firm, not a statutory audit, and it establishes that the failure happened rather than how often it does. New work appearing is also not new headcount: in a billable-hours business an unbilled checking duty is absorbed, which is exactly the condition under which it gets skipped.
