AI-written management accounts commentary

Aipedia, by the Apex broking team · Last reviewed 2026-10-27

Generative AI can draft management accounts commentary quickly, but the accountant must review it as if a junior colleague wrote it. Clients, lenders and buyers act on these narratives, so a wrong explanation can cause a real loss.

Part of: AI in Accountants

In short

Monthly management packs increasingly carry AI-drafted variance commentary and KPI narratives. The risk is a fluent explanation that is simply wrong, for example blaming a margin fall on prices when the cause was a costing error. The ethics Code requires accountants to check technology output is appropriate for its purpose (R320.11) and to explain the limits of the work (R113.3), and the PCRT AI guidance says to treat output as a junior colleague's draft. If a lender or buyer relied on the pack, the claim may come from outside the engagement, which tests both duty of care and PI cover.

How firms use AI for commentary

Outsourced finance and client accounting teams produce monthly packs with a profit and loss, balance sheet, cash summary and a page of narrative. Generative AI tools can read the variances and draft that narrative: why revenue moved, why gross margin fell, what is driving debtor days. Some tools pull the figures straight from the ledger and produce board-ready wording.

This is where AI is most persuasive and least reliable. The tool sees the numbers but not the context, so it explains a movement with the most plausible reason, not necessarily the true one.

The duties that apply

R320.11 of the IESBA technology revisions (in ICAEW's Code from 1 July 2025): decide whether output is appropriate for the intended purpose before using it.
R113.3: explain the limitations of the work. Commentary that reads as analysis but is really a generated summary should say so.
Integrity: an accountant should not be associated with information they know or suspect to be misleading.
The PCRT AI guidance para 3.4: treat AI output as if "prepared by a less experienced junior colleague", and 3.5: members "remain ultimately accountable".

What can go wrong

Illustrative scenario: a firm prepares monthly accounts for a trading company. The AI commentary attributes a margin improvement to "favourable purchasing terms", when in fact stock was overstated after a cut-off error. The directors use the pack to agree a new overdraft and to declare a dividend. When the stock error is found at year end, the company has a cash shortfall and the lender asks questions. The company says it relied on the firm's explanation, not just the numbers.

The commentary is the problem here because it turned a data error into a confident story. A reviewer reading for tone, not cause, would not have caught it.

Commentary also travels. Directors forward packs to lenders, investors and prospective buyers, often without the firm knowing. An explanation written for an internal board meeting can end up supporting a covenant waiver or a price negotiation, which widens the group of people who may say they relied on it and raises the stakes of any error in the narrative.

How PI usually responds

A client claim that commentary was negligently prepared usually falls within a civil liability PI wording, subject to the terms and excess. Claims from third parties such as lenders or buyers depend first on whether the firm owed them a duty of care; see Caparo for accountants. Clear engagement terms on who may rely on the pack, and for what, matter here: see engagement letters and liability caps. More examples are in accountant negligence claims.

Practical controls

Check every causal statement against the ledger or a conversation with the client before it goes out.
Label the pack as unaudited management information prepared for the directors.
State in the engagement letter that third parties may not rely on it without written agreement.
Keep the AI draft and the reviewed version so changes are visible if the pack is later questioned.
Apply the same standard to AI cash flow forecasts and to AI-drafted advice letters that cover the same figures.

Frequently asked

Is it acceptable to send AI-drafted commentary to clients?

Yes, once a competent person has checked that each explanation is supported by the figures and the client's circumstances. The Code requires that judgement before technology output is used, and the PCRT guidance treats the draft as a junior colleague's work.

Can a lender sue us over a management pack we prepared?

Possibly, if the firm assumed responsibility to the lender, for example by knowing the lender would rely on it for a specific purpose. Disclaimers and clear engagement terms help, but the outcome depends on the facts and the Caparo tests.

What should a reviewer check in AI-written commentary?

Check that each stated cause is supported by the ledger, the client's own explanation or a document, not just by the size of the variance. Look for statements of fact the tool could not know, such as supplier terms or customer behaviour, and remove or verify them.

Should management packs say that AI was used?

The PCRT guidance and the CCAB draft Statement both favour telling clients how AI is used, usually in the engagement letter. A short note in the pack itself is optional but helps set expectations about the narrative.
