Web Project StudiosSilent failure audits

Services and prices

One fixed-price audit. Three ways to go further.

The main thing I sell is the Silent Failure Audit: five working days, a fixed fee, permission to look but not change, and a written answer on which of the things your systems do on their own actually happened. If you need more than an audit, I build AI automation that proves it ran, work as a fractional CTO, and do technical due diligence.

01The main offer

Silent Failure Audit

A five-day check of the things your systems do with nobody watching: filings, submissions, deleting old data, reports and the links between systems. Not a hunt for errors, which you already get told about. A check on whether each one happened at all, and whether it produced what it should have.

Best for

Usually someone who has just had a reason to ask: a penalty, a question from an auditor or a buyer, a new role, or a systems change. And where a task that quietly stops means a penalty, not just a nuisance.

Silent Failure Audit: the terms

£1,500–£3,000 fixed

Duration
5 working days
Fee
£1,500 for one area, £3,000 for a full sweep. Fixed.
Access
Read-only, removed at the end
Changes to your systems

Deliverable
Written findings and a one-hour walkthrough call
If nothing is wrong
The report says so, in writing. Same fee.

What the report contains

  1. 01A list of everything in scope that runs on its own
  2. 02Missed runs: what should have happened and didn't
  3. 03Empty runs: what said it finished and produced nothing
  4. 04What each gap could cost you: a penalty, an audit finding or money
  5. 05What to keep an eye on so you can see this yourself from now on

Why the fee is fixed

£1,500 covers a single process area. £3,000 covers a full sweep of your systems. The fee is agreed before I start and does not change based on what I find. That is deliberate: if I were paid more for finding more, you would end up with a report full of findings.

AI automation with a receipt

Everyone sells AI automation. I build the kind that has to prove it ran. Most automations are judged by whether they threw an error. Mine are judged by whether the work actually happened, so every build ships with its own receipt.

Price
Scoped per buildPriced per build, once we've agreed exactly what it does and what counts as done. The checks are part of the build, not an add-on, so they're in the price from the start.
Takes
Fixed scope, agreed up front
Covers
  • The automation itself, on systems you already run
  • Checks that it ran and that it produced something, built in from day one
  • A human sign-off wherever a wrong answer costs money or a filing
  • A weekly line in plain English: what ran, what it produced, what it skipped
  • A handover your own team can run without me
Best for
The job you'd automate tomorrow if you trusted it not to fail quietly. Often one the audit has just turned up.

03

Fractional CTO and interim technical lead

One or two days a week owning the technical decisions on a .NET and Azure estate: architecture, delivery, cost, hiring, and the judgement calls that need someone who has made them before.

Price
£1,000–£1,200 a dayUsually one or two days a week on a rolling monthly arrangement, scaled up or down as the work requires. Remote, working UK and EU hours.
Takes
1–2 days a week, rolling monthly
Covers
  • Architecture and delivery ownership
  • Azure cost and design review
  • Technical hiring and team structure
  • Board-facing translation of technical risk
  • Hands-on work where that's the fastest route
Best for
Companies with a real estate to run and no senior technical owner, or one who has left. Regulated domains especially.

04

Technical due diligence

Assessment of a .NET and Azure target for investors and acquirers, with particular attention to the automated processes a standard diligence checklist tends to take at face value.

Price
Scoped per dealUsually three to eight days depending on the size of the estate and the turnaround required. Available directly or as overflow capacity for diligence firms.
Takes
Usually 3–8 days
Covers
  • Architecture and technical debt assessment
  • Cloud cost and scalability review
  • Delivery capability and key-person risk
  • Compliance-critical automation: does it actually run
  • Written findings suitable for an investment committee
Best for
Private equity, corporate acquirers, and diligence firms needing overflow capacity on the Microsoft stack.

Questions about the services

Prices, scope and what happens if nothing is wrong.

What if the audit finds nothing wrong?

The report says so, in writing, and the fee is the same. It is fixed before I start, so I am not paid more for finding more.

How much does a fractional CTO cost?

£1,000 to £1,200 a day, usually one or two days a week on a rolling monthly arrangement, scaled up or down as the work requires. Remote, working UK and EU hours.

What does technical due diligence cover?

Architecture and technical debt, cloud cost and scalability, delivery capability and key-person risk, and whether the compliance-critical automation actually runs. Usually three to eight days on a .NET and Azure target, with written findings for an investment committee. Available directly or as overflow for diligence firms.

How is AI automation priced?

Per build, once we have agreed exactly what it does and what counts as done. The checks that prove it ran are part of the build, not an add-on, so they are in the price from the start.

Do I have to start with the audit?

No. Fractional CTO work and due diligence stand on their own. The audit is the usual starting point because its findings tell you whether you need anything else.

Not sure which one?

Start with the audit. The rest follows from what it finds.

Tell me about one process that runs without anyone watching it. I'll work out with you how you would currently know if it had stopped, and whether that is worth checking properly.
