Put the client’s numbers in.
Ask what to do next.
Put the whole client file in front of something that has read every rule and every strategy worth knowing — then argue with it. It cites the rule it is relying on; you test it against what you know about the client. Better than either of you alone.
Client financials never leave the building and never touch a public model. That is not a feature; it is the only reason this is possible at all.

Stock — value at 31 March
Director’s loan — sign off
One file — two queries
You cannot put client figures into a public AI, and you know it
A chatbot is somebody else’s computer. The data leaves, it is processed where you cannot point to, and the client never agreed to it. For client financials that is not a preference about tools — it is a data-protection problem, and it is why the most useful technology of the decade is the one you are least able to use.
The strategy work is the first thing to go
Every good idea you have had for a client arrived in a gap between deadlines. When the compliance crunch lands, the advisory thinking is what gets deferred — so the highest-value work in the practice happens in whatever time is left over, or not at all, and it is the work that would have kept the client.
The knowledge is in one or two heads
The senior partner knows the relief, the timing rule and eight years of that client’s history. When they are away, or when they retire, it goes with them, and it takes a junior three years and a lot of mistakes to rebuild.
A machine on your desk, working on your files.
Strategy, worked out with you, on that client’s own numbers
Load the financials and ask the question plainly: what could be done for this client this year? It comes back with the reliefs that might apply, the timing that helps, the structure worth raising — and the rule it is relying on for each one. Then comes the part that matters. You push back. It has the rules and the plays; you know this client, the family, the last eight years and the risk they will actually take. It is two-way, in the room, on your own machine — and the answer is better because both of you were in the conversation.
The rulebook for where your clients actually are
It comes loaded with the tax, reporting and filing rules for the jurisdictions you work in, and it knows which one applies to which client. A practice with UK and Irish clients, or a German client with a UK subsidiary, stops carrying two rulebooks in one head — and stops checking last year’s rates from memory.
The forms, drafted for you to improve
Engagement letters, onboarding packs, management commentary, the standard letters and routine filings come back drafted in your practice’s own language. The typing is what disappears — not the judgement. What is left is the part you spent years learning: reading it as a qualified person who knows what to look for, and changing what needs changing. That is a better use of someone who can spot the thing a template never would.
Memory is the part of this machine the market is currently restricting. If the shelf is short, you hear the ETA before you pay — not after.
Price tracks the DRAM contract and is reviewed monthly.
The machine
It stands on the desk and works on your files.
A small black case with one spine of light. Your files, your rulebooks and its own model sit inside it, and nothing it works on leaves the room.
- Height
- 16 cm
- Case
- Matte black, pierced
- Name
- Engraved, filled in gold
- Cloud
- None — it runs where it stands
The Centurion
The same Centurion, wherever you are.
What stands on the desk is the whole of it. The phone is a window onto that same machine — not a second assistant and not a copy in someone else’s cloud. Same files, same rulebook, same memory.
Every conversation stays in the list, on both, in the order you last touched it. Ask it on the train; finish it at the desk.

The build sheet
Four questions about your practice, and the specification engraves itself.
Where your clients sit, the work you sell them, the sectors you serve and the work you would stop doing. No account and no card. The link carries the whole brief, so you can send it to a partner before anyone speaks to us.
The machine is the hardware. This is what is loaded into it before it reaches your office — and it is the part that makes it worth having.
The rulebook
The tax, reporting and filing rules for the jurisdictions you nominate, kept current. It cites the rule it is relying on so you can check it rather than trust it.
The strategy library, for you to test against this client
The plays that work, loaded from the practitioners who wrote them down — the classic strategies as well as the current ones. Most of what is genuinely good was written before either of us started, and a machine that only knows this year has a shallow bench. It is not there to choose. It is there so that when you reach for the move, you can see the alternatives nobody has time to think of at nine at night. The choosing stays with you.
Your own files
Prior-year accounts, engagement letters, the correspondence, the way your practice writes. It drafts like your firm because your firm is what it was taught.
The client, when you choose
One client’s file can be loaded for one conversation, and it stays on that machine. Nothing is pooled, nothing trains a model elsewhere, nothing survives a client leaving.
The ideas that never got off the ground
One customer, on what stopped waiting for other people — and what started moving instead.
“I had so many ideas that never got off the ground — always waiting on other people, never getting the answers I needed, losing momentum. Now I'm powering through them. It's not just answering questions: it gives me ideas, helps me think through problems, and keeps my projects moving. I wake up excited — like having someone incredibly capable in your corner, 24/7.”
Answered here, so you do not have to book a call to hear them.
Is this the compliant way to put client data into an AI?
It is the only route that does not create a transfer problem. The machine is in your office, the data stays on it, and there is no third-party processor holding your clients’ figures and no cross-border transfer to account for. You remain the controller and the processor is your own machine. Compare that with the data-processing agreement, the transfer assessment and the retention questions a cloud tool asks you to answer on behalf of every client you have.
Does this reduce what the accountant is for?
It is built on the opposite assumption. The rules and the strategies are the part that can be written down and loaded — and they are already in books nobody has the hours to read. What cannot be loaded is the judgement: what this client will actually do, what the family dynamic is, how much risk is sensible, what to say and when to say it. That is the accountant, and it is the scarce part. This puts the whole written body of the profession in the room so that your judgement is applied to all of it, instead of to whatever you could hold in your head at nine at night. It magnifies the practice. It does not stand in for it.
Does it give advice?
No. It drafts, it suggests, it does the arithmetic and it shows its working. The judgement, the recommendation and the signature are yours, and nothing leaves the practice under its own name. It has read the books; it has never met your client. That is the whole division of labour, and it is the reason the two of you are worth more together than either is alone.
Will it invent a relief that does not exist?
It can be wrong, the way any first draft can be wrong. That is why the output is a draft and your review is the control. What changes is the standard of the starting point and how much is left to correct — and it is instructed to cite the rule rather than assert the answer, so you can see where it came from.
We have clients in more than one jurisdiction.
Then it holds more than one rulebook and tells you which applies. That is the whole reason for loading the rules rather than hoping a public model remembers last year’s thresholds for a country it was never given.
What does it cost, and what if it is not for us?
The price is published on this page and there are no add-ons on an invoice later. If you want the quality demonstrated before the machine, a First Build is €1,500 — one deferred job, ten working days, done. There is also a fourteen-day cancellation on the machine itself.
Two prices. Neither is hidden.
The same machine, the same licence, the same support. Pay once and it ships in fifteen working days. Pay monthly and you are working within five — and you own it at the end. The lease is twenty per cent more over the term, and that difference is the price of being paid later, not an interest rate dressed up as one.
- Working within five working days, hosted privately for you
- The machine arrives in month six, memory moved onto it
- Licence included for the whole term
- No credit application and no credit file pulled
Signed and paid in one step. Read the agreement first — it is the document you accept at checkout.
- Arrives in fifteen working days
- The machine is yours from the first day
- Twelve months of licence included
- Stop at any time and keep everything
Secure card payment. Your receipt is immediate and the fourteen days to change your mind run from delivery.
Or order by invoice — the invoice follows within one working day.
| Lease to own | Buy outright | |
|---|---|---|
| Price | 24 monthly payments | One payment |
| Cost over the term | Twenty per cent more | The cash price |
| When you are live | Five working days | Fifteen working days |
| The machine | Arrives in month six | Ships immediately |
| Ownership | Title transfers at month 24 | From day one |
| Commitment needed | A monthly commitment | A capital decision |
| If you stop | The licence ends and the machine returns | You keep the machine and your memory |
The lease is an agreement drafted by a solicitor before it is offered, and you will see all of it before you sign anything. It is a subscription for a service with an option to purchase the equipment at the end of the term — not a regulated credit agreement, and no credit file is pulled. Because the machine cannot run without the licence and the licence is ours, the equipment itself is the security; that is why a small organisation with no borrowing history can have one.
Centurion Brain, in full
A small, quiet machine that sits on your desk and runs entirely in your office. It is specified, assembled, installed and tested before it ships, so it arrives working rather than arriving in boxes with a project attached.
See the machine and the price- A Centurion Brain — the machine itself, for your desk, running in your office
- Specified, assembled, activated and tested before it ships
- Your assistant on it, configured for your business before it leaves the bench
- A travel case, because the machine is yours and it goes where you go
- One setup card: plug in, join your wifi, wait for the light
- A named person and a dated call in week one
- Centurion Remote for iPhone and Android, for as long as you hold the licence
- Twelve months of licence, updates and support
Not for a practice that wants the machine to sign the file, and not for one that would not put client data near a machine at all. Both are reasonable positions, and this is not the product for either.
Do the arithmetic yourself
You price time for a living, so the only honest thing to do here is put the numbers on the page and get out of the way.
The saving does not begin when the machine arrives. It begins the week the first client file goes into it — which is why the honest comparison for most practices is not the price of the machine against zero, but the price of the machine against the work that is not being done.
One machine. Two ways to pay for it.
Pay once and it ships in fifteen working days. Pay monthly and you are working within five, hosted privately for you, and the title transfers at month 24. Every figure and every term is stated above — you do not have to book a call to hear them.
Tax treatment is described as a UK example only and is not tax or accountancy advice. Centurion AI supplies software and hardware; it does not provide accountancy, tax or legal advice. Rule sets are loaded per jurisdiction and should be checked against the current published rules.
