A note from Ollie
Why not use a Big Four firm?
I am often asked what is different about us. My answer starts with what we have in common. As a PwC Director I was the national lead for independent quality assurance, and I am still brought in for complex reviews. You get Big Four experience without the badge, or the price tag.
What is different is how we work. I have delivered and recovered complex IT projects in the UK, the US and Europe, not only reviewed them, so our recommendations come with the practical detail to carry them out. Large-firm reviews tend to be punitive and to play down what went well. A payroll team that has just found an underpayment is under enough strain, and it is entirely possible to find what went wrong without blame.
Geoff and I are independent, with no ties to any payroll software vendor.
How we work
From the outside, and accountable for every line
From the outside
We are not your payroll provider, your IT provider or your AI vendor. We have no system of our own to defend, so we can tell you what we find.
Independent
We report what the evidence shows, with the working, even when the answer is awkward. Fixes are optional and quoted separately, so the audit never depends on selling them.
Every finding read by a person
The engine reads everything. One of us reads every finding it raises before it reaches you, and both of us stand behind the report.
Plain English
Short reports a busy owner or finance lead can read in one pass, with the detail behind every line for whoever needs it.
Openly AI-powered
How the AI is used
Two senior people run every engagement. The checking is done by software that AI helped us build and that we test against known answers, so it is fast, repeatable and cheap to run. Our hours go on judgement, not data entry.
AI does the reading and the arithmetic
We use AI to build and run a rule engine that reads 100% of the records in scope, not a sample, and works through every calculation. The same data gives the same answer every time.
People set the rules
We decide what the engine checks, from the legislation and the published guidance, and we test it against files with planted errors before it runs on yours.
People read every finding
Nothing reaches you that one of us has not read and checked against the working. Where a finding needs judgement, it gets ours, not the machine’s.
People write the words
The report text is assembled by our rule engine from sentences the two of us wrote. No generative model writes a finding, and we sign the report.
Claims we can back
Every speed, cost and accuracy claim on this site links to a public source, caveats included, and we publish our own test results. Where the evidence is thin, we say so.
Talk to us about an audit
A short call to scope it. A fixed fee before we start. Big Four experience, without the junior team or the Big Four fee, in days not months.
