The advantage goes to whoever puts AI into production first.
Where the money is
Five places we usually start. Each one moves a number your board tracks.
High-volume, rules-based work in finance and operations. We start with one, prove the return, then move to the next. These five are a starting point, not a limit.
Credit control and cash collection
“Too much cash sits in debtors, and chasing depends on who's in.”
Chasers sent on schedule in your tone, remittances matched, disputes flagged, and a daily view of cash.
One week off debtor days on £50m revenue releases about £960,000 of cash.
Measured in debtor days and overdue £Month-end close and board pack
“Close takes eight days and the pack is built in Excel.”
Reconciliations run automatically; variance commentary and the pack are drafted for review.
Measured in days to closeOrder intake and quotes
“Orders arrive as emails and PDFs and get re-keyed.”
Orders read and entered into your system; quotes drafted within hours for sales to approve.
Measured in hours to quoteOnboarding and document checks
“Setting up a customer or supplier takes a week.”
Documents collected and checked, Companies House and credit checks run, gaps flagged.
Measured in days to onboardNot on the list?
If a process is high-volume, rules-based and still done by hand, we can automate it. Bring it to the briefing.
- Purchase order matching
- Expense claims
- Supplier statement reconciliation
- Payroll inputs
- Stock reconciliations
- Timesheets and billing
- Contract renewals
- Customer service inbox
- HR onboarding
The cost of waiting
Every month you wait has a price.
Put in your own numbers for cost or for cash. The audit replaces these assumptions with measured figures.

Cash released = annual revenue ÷ 365 × days taken off. Borrowing cost saved assumes the released cash reduces your borrowing.

Before
Automation audit from £7,500
Two weeks. Credited in full against your deployment.

Handover support £1,000 a month
Every fault in what we built fixed, with guaranteed response times. Six hours a month of changes and training, while your team learns to run it. Covers up to two live processes.
What support includesThen
It's yours to run no licence
No lock-in and nothing more to pay. Need us later? £100 an hour. Start your next process during handover and support is free while we build it.
How your team stays in control
Nothing breaks at month-end. Nobody loses control of the ledger.
What your finance team, IT and auditors will want to know, answered up front.
We run alongside first
The system runs in parallel with your team until the numbers match. Then you switch over.
Your team approves
Payments, customer messages and anything over a threshold wait for a person's sign-off.
Full audit trail
Every automated action is logged and can be reviewed by finance or your auditors.
Your environment
Runs in your cloud or on your servers. Your data stays under your control.
Data terms first
UK GDPR data processing terms are signed before we see any data.
You own it
Code, documentation, tests and credentials are handed over at Day 30.
Why us
We don't sell AI strategy. We deliver systems that pay.
You've seen the decks, the day rates and the pilots that quietly disappear. We removed every one of them.

Who we work with
We're selective. It's why it works.
We take on two deployments at a time and turn down work we can't deliver in 30 days.
We're a fit if
- You're a UK business with 50 or more people
- A process runs hundreds of times a month, mostly by hand
- A senior leader owns the outcome and can make decisions
- You want results measured, not promised
We're not a fit if
- You want an AI strategy deck
- You want ten pilots at once
- Nobody owns the result
Check your fit
Five questions. Thirty seconds.
Do you have 50 or more people?
Does one process run 500+ times a month?
Is it mostly done by hand today?
Will a senior leader own the outcome?
Could you start within the next quarter?
Answer all five
We'll tell you straight whether a briefing is worth your time.
Questions
What finance leaders ask us first.
- Will it disrupt month-end?
- No. We run alongside your team until the numbers match, and only then switch over.
- Will my team resist it?
- Your team approves every exception and keeps control of the ledger. The work they lose is the re-keying.
- What happens when the AI gets it wrong?
- Anything uncertain or over a threshold goes to a person to decide. Every action is logged.
- Where does our data go?
- It runs in your environment, under a signed UK GDPR data processing agreement. AI providers are used on business terms that don't train on your data.
- Why not just buy accounts payable software?
- Off-the-shelf tools fix one step and add a licence. We automate the whole process across the systems you already have, and you own it.
- What does it cost to run afterwards?
- Only AI model usage and hosting, paid directly in your own accounts. For accounts payable at 1,500 invoices a month that's roughly £20 to £90. The audit confirms the figure before you commit.
- Who looks after it once it's live?
- We do for the first two weeks, included. Then three months of handover support at £1,000 a month, while we train your team to run it. After that it's yours, and we're on call if you need us.
- How do we pay?
- The audit is paid upfront and credited in full against the deployment. The deployment is paid half on signing and half at go-live. Handover support is billed monthly in advance.
Next step
The margin goes to whoever moves first.
In 30 minutes we'll tell you whether one of your processes is worth automating and what it's worth. If it isn't, we'll say so.
