AI, Explained for the CFO

No jargon. One idea, four numbers, one spending rule — and the question to ask before signing anything.

The one idea that matters

AI assistants answer from your company's filing. Tools like Microsoft Copilot read what your business already has — documents, spreadsheets, email — and answer questions from it. That is the whole product.

Which means: if your filing is five versions of the same report, a tracker spreadsheet someone keeps "their copy" of, and folders shared to everyone since 2023, you are about to pay a monthly fee per person for an assistant that confidently summarises the wrong version. The assistant isn't broken. The filing is.

Nobody sells you this sentence, because the fix isn't a licence — it's work.

Why "just buy the licences" is the expensive option

The pattern repeats everywhere: seats bought for everyone, no preparation, and within 90 days the organisation's verdict is "we tried AI and it was mediocre." That verdict is the real cost — not the wasted subscription, but the two years of internal cynicism that follow it, while competitors' teams quietly get faster.

The counterintuitive truth: the IT tidy-up you've deferred for years and the AI programme are the same project. Sorted filing, sensible permissions, one authoritative version of each number — that isn't preparation for AI. On current technology, it is most of what makes AI good.

The four numbers to ask for

1

What are we paying Microsoft today — and how much is waste?

In organisations under ~200 people that have never audited licences, 15–30% of the spend is typically recoverable: seats for people who left, duplicate subscriptions from old entities, add-ons nobody opens. The audit usually part-funds the AI programme. Ask for this number before approving anything new.

2

What does a seat cost, and what makes it earn that?

An AI seat costs roughly a coffee-shop lunch per person per week. It earns that only if the person uses it on real work — a training and habit question, not a licensing one. Demand a usage report at 90 days, not a feelings survey. Unused seats get cancelled.

3

How many hours does our monthly reporting cycle consume?

Assembling packs by copy-paste is where document-heavy businesses bleed time — and the first place a well-grounded assistant pays for itself. Baseline it now so the after can be measured against a before.

4

What could leak?

These assistants respect your existing permissions — exactly as they are. If a confidential folder was over-shared years ago, the assistant will cheerfully surface it to whoever asks. It doesn't create the exposure; it reveals it. A permissions review before rollout is incident insurance, and it's cheap.

The spending rule: never fund more than the next gate

AI programmes fail as big-bang purchases and succeed as gated investments. Each stage produces evidence before the next rand is approved:

GateYou're buyingEvidence before the next gate
1 · Audit2–4 weeks of discoveryThe waste number, the risk list, a costed plan
2 · FoundationsTidy filing, fixed permissions, staff trainedPermissions test passed; literacy sessions done
3 · Pilot seatsA small licensed group, defined use casesUsage data + hours saved, in writing
4 · RolloutSeats where the pilot proved valueAdoption holding; dormant seats culled
5 · AutomationAI doing multi-step work, human sign-offEvery flow with an owner and audit trail

The board never approves "an AI strategy." It approves the next gate, every time, on evidence. This is also your protection against vendor enthusiasm — including ours.

The people part (which is most of it)

Literacy for everyone — a few hours, not a course: what these tools are genuinely good at (drafts, summaries, finding things), where they fail (they state errors with total confidence), and the one rule that prevents most incidents: if you didn't sign in with your work account, don't put work information into it. Your staff are already using free AI tools with company data — the choice is between governed use and invisible use, not between use and no use.

Accountability stays human — the person who sends it, owns it. AI drafts; people decide. No AI-made decisions about people or money. That sentence is most of your AI policy, and your auditors will ask for it in writing.

Trial discipline: start free trials, diarise the expiry, switch off auto-renewal the day you start. Yes, this applies to AI subscriptions too. Especially to AI subscriptions.

What good looks like in 12 months

Measured, not vibed: licence waste recovered; reporting-cycle hours down against the baseline; every seat active or cancelled; zero data incidents; one or two carefully-governed automations doing real work with a named human approving the output. Not "transformation" — a tidier, faster, better-protected business where the AI spend is justified line by line, and a foundation on which the next wave of AI (coming regardless of what you approve this quarter) lands well instead of badly.
