The biggest opportunity AI creates for accountancy practices isn't replacing accountants. It's giving them their time back. And the real opportunity lies in what they do with that time.
Across business, AI is increasingly taking on repetitive, process-heavy work. Legal firms are using it to review contracts in minutes rather than days. Banks use it to monitor transactions for suspicious patterns. HMRC uses machine learning to identify anomalies in tax returns.
The same shift is happening in accountancy. AI is increasingly able to handle the reading, matching, summarising and pattern-spotting that sits behind routine accounting processes. That doesn't remove the need for accountants but creates capacity for more high-value work.
The data is there. The intelligence has lagged.
The accounting industry has been talking about automation for a decade. Bank feeds, rule-based categorisation and receipt capture arrived years ago. Making Tax Digital has pushed most small businesses onto cloud software, so the data exists, and it's structured.
What has lagged is intelligence. Most "AI" in accounting software today still means discrete, well-bounded tasks: OCR reading a receipt, data extraction, categorisation, bank reconciliation. Useful, but narrow. What it doesn't yet do, in most practices, is run an end-to-end workflow: take a piece of work from first contact to filed return without a human stitching the steps together. The accountant is still reviewing the ledger line by line, still chasing the client for missing receipts, and drafting the same explanatory email.
Meanwhile the pressures on small practices are real: fee compression, staff shortages, and clients who expect instant answers. The firms that win the next five years will be those that use technology to create more capacity and then use that capacity intelligently.
If AI gives an accountant back several hours every week, those hours can be reinvested into higher-value activity: talking to clients, providing proactive advice, identifying services they may need, strengthening relationships and improving retention. Partners can spend more time meeting prospective clients, developing their profile and winning new business.
For a small accountancy practice, that changes the economics of growth. Increasing revenue and client numbers no longer requires headcount to increase at the same rate.
That shift is already visible in a handful of areas. AI review tools are starting to read a client's bookkeeping and flag what looks wrong: a duplicated invoice, VAT treated inconsistently, an expense that doesn't match the pattern of the business, turning a ledger someone has to wade through into a short list of things worth a second look.
At Nomi, we're already building around this principle, alongside specialist agents for VAT, Self-Assessment and Corporation Tax that check a return against the rules and explain their reasoning in plain English. Reporting is changing shape too, with live data paired with a written narrative so a client gets a paragraph explaining what moved and why, rather than a spreadsheet to decode.
Another area where technology can create capacity is by removing friction from everyday client interactions. Meeting business owners where they already are, rather than asking them to log into yet another portal, matters more than it sounds. We've had good results simply letting clients send a receipt over WhatsApp and having it read and filed automatically. The same logic applies to timing: catching a client who's gone quiet, or a deadline that's creeping up early enough to do something about it.
And increasingly, this intelligence is turning outward - voice and chat agents handling credit control calls and inbound queries, having substantive conversations with clients.
The risks are real, and worth naming
However, AI in a regulated profession carries genuine risk, and any serious approach must design around the risks.
Hallucination is the obvious one. An AI that confidently invents a tax rule is worse than no AI at all. The answer isn't to avoid the technology; it's to build systems that show their working, cite the data used, and say, "I'm not sure".
Less obvious but more dangerous, is silent failure: an agent that logs a task as complete when it actually failed. Good design treats this as a hard rule: every automated action should end in a verified outcome or an alert to a human. It's a discipline worth applying to the engineering itself: at Nomi, our own code gets reviewed by AI overnight, with a report waiting each morning, on the principle that nothing gets to assume it's fine.
There is also the wider issue of security. Accountancy platforms handle highly sensitive financial, tax, payroll and banking information. Any use of AI therefore needs clear controls around what information is processed, where it is processed and what actions technology is permitted to take.
Underpinning all of it must be a human in the loop: nothing filed, sent or committed without an accountant's sign-off. AI prepares; people approve.
Finally, there's over-reliance. An AI review is a second pair of eyes, not a substitute for the first.
Where the sector is headed
Within a few years, "year-end" may stop being a single, dreaded event. Books reviewed continuously by AI will stay close to final all year round, and the accountant's role shifts from catching up to looking forward.
Compliance work is likely to become largely invisible to the client while advisory conversations become the visible product.
The direction of travel isn't AI replacing accountants. It's AI working alongside them, with technology taking on the repetitive workflow while people provide the judgement, reassurance and relationships clients value.
But the winners aren't the practices that automate the most. They'll be those that make the best use of the time earned back.
If that time is simply absorbed elsewhere, AI becomes an efficiency tool. If it is reinvested into better advice, stronger client relationships, improved retention and winning new clients, it becomes something much more powerful: a growth tool.
That's where I believe the biggest opportunity lies for small accountancy practices. Not fewer accountants, but accountants spending more of their time doing the things that create value for clients and growth for their practice.
