Before we start
AI never says "I'm not sure." It says the wrong thing with exactly the same confidence as the right one. That single trait is behind nearly every AI horror story in our profession.
THIS WEEK RECONCILED
AI is fluent. That isn't the same as right.
There's a particular kind of wrong that only AI does, and it's the one that'll catch you out.
A junior who's unsure hedges. "I think it's this, but let me check." That uncertainty is a gift — it tells you exactly where to look. AI doesn't do that. Ask it something it only half-knows and it hands back a confident, fluent, perfectly formatted answer that happens to be wrong. Same tone as when it's right. No flicker of doubt.
It once gave me a tax rate quoted to the decimal, with a plausible-sounding justification, that was simply last year's figure. If I hadn't already known, I'd have used it.
THE TRAP
"The relevant threshold for 2026/27 is £12,570, as confirmed in the Finance Act 2025, s.34." — fluent, specific, cites a section. It can also be entirely invented. The confidence is not evidence.
That's the trait to burn into your team's heads: AI is fluent, not accurate. It will invent a piece of legislation, cite a case that doesn't exist, and quote a made-up statistic — all in the register of a confident senior manager. It isn't lying. It has no idea it's wrong, which is worse, because it can't warn you.
The fix isn't distrust. If you re-check everything from scratch, AI has saved you nothing. The fix is a named habit — the Reconciled Review Method: AI-assisted, human-verified. Every piece of AI work gets a review step that's a real step, with an owner, not a vague "someone will glance at it." On anything factual, you verify the claims, figures and references against source before you rely on them. That's not bureaucracy. It's the same reason you review a junior's file before it leaves the building.
There's a quieter danger underneath, and it worries me more. If your team leans on AI for the thinking, not just the typing, the skill quietly erodes. You end up with people who can prompt but can't judge whether the answer's any good. So the review habit does two jobs: it catches today's errors, and it keeps your people sharp enough to catch tomorrow's.
The signature on the work is still yours. The tool doesn't carry the risk — you do. So the review trail, not the model, is what actually protects the firm.
RECONCILED IN PRACTICE
Make the check a real step
Pick one workflow where you already use AI and add a verification step that can't be skipped:
Name it — "AI-assisted, human-verified" goes on the file or the workflow, so everyone knows the draft isn't the finished article.
Own it — a specific person does the check, the same way a specific person reviews a junior's work. "The team" owns nothing.
Verify the facts, not the vibe — every figure, date and legal or HMRC reference gets checked against source. Fluent formatting is not a tick.
Done once, it stops being a chore and becomes reflex — the same reflex you already have for reviewing anything before it goes to a client.
Rich's Take
AI is fluent, not accurate — and fluent is dangerous, because it reads like competence. The signature is still yours, so the review trail, not the tool, is what protects the firm. Treat every output like a keen junior's first draft: useful, and never filed unchecked.
YOUR QUESTIONS RECONCILED
"How do I stop my team trusting AI output blindly?"
Don't rely on telling people to be careful — build the check into the workflow so it can't be skipped, and give it an owner. Then do the thing that actually shifts behaviour: show them. Next time AI confidently invents a figure or a reference, share it with the team. One vivid example of a fluent, authoritative, completely wrong answer does more than any amount of "please double-check." Once they've seen it lie with a straight face, they never fully trust it again — which is exactly where you want them.
Golden rule, restated: a good prompt earns you a strong first draft, never a final answer. Whatever comes back, it's checked against source before it reaches a client. You're still the accountant.
PROMPTS RECONCILED
Make AI flag its own risky claims
You can't stop AI being confidently wrong — but you can make it show you where to look. Run this over any AI-drafted output before you rely on it:
"List every factual claim, figure, date and legal or HMRC reference in the text below. For each one, mark whether I must verify it against source before relying on it. Do not correct them — just flag them, and note which are most likely to be out of date or invented. [paste the text]"
It turns a wall of confident prose into a checklist. You still do the verifying — but now you know precisely which lines to distrust.
This week
Add the "AI-assisted, human-verified" step — with a named owner — to one workflow where you use AI. Then hit reply and let us know how you got on, and tell us the best confidently-wrong answer AI has ever handed you.
Next week in Reconciled
You've got the colours and the check habit. Next week we write them down: the one-page AI policy, plus the engagement-letter wording that now needs to match it.
