What finance teams should document when AI is used in reporting before the audit

Accendo · 2026-07-28 · Reviewed 2026-09-26

AI is starting to appear in corporate reporting, but its use remains cautious and uneven.

Recent Financial Reporting Council research found that the use of AI in corporate reporting is increasing, with generative AI being used particularly in narrative reporting. Its use in financial statements remains more limited, and corporate reporting remains strongly human-led.

For finance teams, the practical issue is not whether AI can be used at all. It is whether any AI-supported output, analysis or draft disclosure can be traced back to reliable source data, reviewed by someone accountable and explained clearly if the auditor asks.

AI can support reporting, but it does not change management’s responsibility for the final figures, judgements and disclosures.

You can read the FRC’s research here: Corporate reporting remains human-led amid growing adoption of artificial intelligence.

The FRC also published guidance in March 2026 on the use of generative and agentic AI tools in audit engagements. That guidance is aimed at audit firms. It does not create a new standalone reporting obligation for finance teams, but it does show the wider direction of travel: AI-supported work needs appropriate oversight, documentation and professional judgement.

Where AI may appear in finance reporting

AI use in finance teams is not always obvious.

It may sit inside software, spreadsheets, reporting tools, data analytics platforms or general productivity tools. It may be used formally by the finance team, or informally by individuals trying to work more efficiently.

Common examples may include:

These uses may be helpful, but they also create questions. What source data was used? Was the output checked? Was the tool appropriate for the task? Who reviewed the result? Can the business explain how the final figure or disclosure was reached?

These questions matter before the audit begins, not after the auditor raises them.

AI support is not the same as reliable evidence

An output that looks plausible is not the same as one that is correct.

That is one of the main risks when AI is used in reporting. A draft paragraph may read well but include a statement that is not supported. A summary may miss an important exception. An analysis may rely on incomplete or unreconciled data. A tool may produce an answer without showing enough of the process behind it.

Finance teams should therefore treat AI-supported outputs as starting points, not final conclusions.

Before relying on them, management should be able to show:

The aim is not to prevent useful technology from being used. It is to make sure the business can trust and explain what is being reported.

What auditors may ask

Auditors are unlikely to object to technology simply because it has been used. The issue is whether the output can be evidenced and whether management has applied appropriate review.

If AI has supported any part of the reporting process, auditors may ask questions such as:

These questions are not only technical. They go to the reliability of the reporting process and the strength of management oversight.

Data quality, transparency and explainability

AI is only as useful as the information and controls around it.

If the source data is poor, incomplete or unreconciled, the output may be unreliable. If the tool’s process cannot be understood or explained, it may be difficult to evidence. If no one owns the final review, accountability becomes unclear.

The FRC’s work on AI in corporate reporting highlights risks around error, data quality, transparency and explainability. These are practical issues for finance teams, especially where reporting needs to withstand audit, lender review, investor scrutiny or buyer due diligence.

A good process should therefore make clear:

Technology may speed up reporting, but speed is only valuable if the output remains reliable.

Controls finance teams should document

A sensible control process does not need to be overly complicated.

It should give management and the auditor a clear view of where AI is used, what it produces and how the output is reviewed.

Useful controls may include:

The aim is confidence in the reporting process, not paperwork for its own sake.

Why human review remains central

AI can assist with analysis, drafting and summarising information, but it does not replace professional judgement.

Finance reporting often involves judgement about provisions, impairment, going concern, revenue recognition, estimates, assumptions, disclosures and the presentation of performance. These areas require management to understand the business, assess evidence and take responsibility for the conclusion reached.

Human review is especially important where:

A finance team should not rely on an AI-supported output simply because it appears fluent, detailed or consistent. The question is whether it is right, complete and supported by evidence.

Questions to ask before the audit

A short internal review before audit fieldwork can reduce difficulty later.

Useful questions include:

These questions help move AI use from an informal productivity tool to a controlled part of the reporting process.

Keep a short record of each significant AI-assisted output

Record the purpose, tool and version where available, source data, output date, reviewer, checks performed and final decision. For example, reconcile AI-generated variance commentary to the management accounts and remove explanations the evidence does not support. Retain the approved output without unnecessarily duplicating confidential inputs.

Protect confidential information

Use tools and account settings approved by the organisation. Check the relevant contractual, confidentiality and data-protection requirements before entering personal or client information. Do not assume an AI answer is a source, or that a citation is valid without opening and checking the underlying document.
