What Is Agentic AI in Audit — and What Can It Actually Do Today?

Audit Technology
“Agentic AI” is attached to almost every audit-technology announcement this year. For a working auditor the useful question is not whether it is coming, but what one of these systems can actually do on a live file today — and where it still cannot be trusted. This is a plain read for independent and mid-sized firms, without the conference-stage gloss.

The word that is doing a lot of work
Most software an auditor has used is an assistant: you ask it something, it answers. An agent is different. You give it an objective, it breaks that objective into steps, uses tools and data to carry them out, and returns a result together with a record of how it got there. Systems marketed as “agentic” are usually described in three parts — reasoning over plain-language instructions, drawing on the firm’s own documentation and rules, and taking defined, logged actions.
The distinction that matters on an engagement is simple: an agent does not just describe the work, it attempts to do it, and it leaves a trail behind. Whether that trail is good enough to rely on is the whole question — and it is an auditor’s question, not a vendor’s.
What it can genuinely do on an audit today
The real, current uses are narrower than the headlines and more useful than the skeptics expect. In practice, agentic tools are being used to draft a risk-and-control matrix from a client’s process description, propose a testing strategy for an assertion, gather and organise supporting documents, and produce first drafts of routine deliverables and reportable observations. Work that used to take a day of assembly can come back as a draft in minutes.
Notice what that list is and is not. These systems are fast at the assembly and coordination work — the reading, extracting, matching and drafting that has always eaten junior hours. They produce drafts and organised evidence, not conclusions. The analytically difficult part of an audit was never the assembly; it was the judgment applied afterwards.

Auditor reviews & decides

Where it stops — and where you stay responsible
The limits here are not incidental gaps that a later version will close. They are the job. An agent can flag an exception; it cannot decide whether the evidence obtained is sufficient and appropriate for the assertion being tested. That judgment, and the professional skepticism behind it, sits with the auditor under ISA 200 and ISA 500. The IAASB is revising ISA 500 on audit evidence precisely because tools now sit between the auditor and the source document.
Two cautions are worth carrying into any pilot. The first is reliability: if you cannot see how a tool reached an output, you cannot easily judge that output’s reliability as evidence — which is exactly what ISA 500 asks you to weigh. The second is authenticity. The same technology that can read a document can fabricate one, so the value of an agent is less that it organises evidence quickly and more that it lets you trace each item back to where it came from.
What this means for a smaller firm
The launches that make the news come from the largest firms with matching budgets, which makes agentic AI sound like something that happens elsewhere. The more useful trend for an independent practice is quieter: the capability is arriving inside the tools you already use, on the files you already have, rather than as a separate enterprise platform you must adopt wholesale.
The part of a test of details these tools handle well is the same part that has always consumed junior hours — reading mixed supporting documents, extracting the fields that matter, and lining them up against the accounting records. That specific step, turning a folder of invoices, CMRs and contracts into matched, review-ready evidence inside Excel, is what DocMaster automates today; you can see the full workflow in how it works. The judgment stays with you; the coordination does not have to.
The honest summary
Agentic AI in audit is real, and it is genuinely useful for one thing: doing the assembly work fast and leaving a trail. It is not a substitute for the auditor’s evaluation, and a system that produces evidence you cannot trace is a liability rather than a shortcut. Treated as a fast, reviewable junior rather than an oracle, it earns its place on the engagement.
Frequently asked questions
No. A general chatbot answers prompts. An agent is given an objective and carries out multi-step work with tools and data, returning an output plus a record of the steps it took. That record is what makes it usable on an audit.
No. It can draft matrices, gather evidence and flag exceptions. Deciding whether evidence is sufficient and appropriate — and taking responsibility for that decision — remains the auditor’s under ISA 200 and ISA 500.
It can support the file, but you must be able to assess its relevance and reliability. If you cannot see how the tool reached a result, that is harder to defend. Traceability, not just speed, is the test.
Increasingly, no. The practical route for a smaller firm is capability built into the tools you already run, rather than a separate enterprise platform bought and rolled out wholesale.
