Build · zero to one
We build it at a fixed price, against tests you have agreed in writing.
From an idea on a page to working software in your hands. Our own AI tools do much of the build work under close direction, and every line is reviewed, tested and signed off by a person. That is why it’s fast, and why you can check it.
Fixed price, from £40,000. Written acceptance tests before any build work. You pay for results, never hours.

How to start
Four steps, each one checkable.
- 01
A first conversation
You tell us what you want to exist. We tell you straight whether it needs building at all, or whether a tool off the shelf will do.
Free
- 02
Discovery Sprint
You leave with a written specification, a working prototype you can click through, acceptance tests in plain English, and a fixed price for the build.
2 weeks
- 03
Build, in milestones
Each milestone ends with a demo and an evidence pack: the tests and their results. You have 5 working days to accept it against the tests you agreed. You pay on acceptance.
Typically 4–12 weeks
- 04
Handover
The code, the full test suite and the documents are yours on payment. We can run and support it afterwards if you want us to. You are never locked in.
On final acceptance
What you get
Fixed price. Tests first. Your code.
- A fixed price, from £40,000, agreed before the build starts. You pay for results you can check, never hours.
- Written acceptance tests, agreed with you in plain English, before any build work.
- A weekly written update, and a change log: every change request gets a written answer within the week.
- Working software you can use, tested against what you asked for.
- The source code and the test suite, owned by you on payment.
The kind of thing we build
Where a tool off the shelf won't do.
- A quoting engine
- Turn a customer request into a priced quote, checked against your own rules.
- A reporting tool
- Pull numbers from the systems you already have into the report you need.
- An assistant for your own documents
- Answers only from your files, and shows the source for each answer.
- A new product
- An AI product or service of your own, from first idea to first customers.
What we don't do
No hourly billing, no surprises.
- We don’t bill by the hour. The price is fixed before work starts.
- We don’t build what a tool off the shelf would do. We say so and name the tool.
- We don’t start without written acceptance tests you have agreed.
- We don’t lock you in. The code and tests are yours on payment.
Who does the work
One accountable director. No hidden team.
Our director leads every build personally and is the person you speak to. AI agents do much of the build work under his direction; a person reviews, tests and signs off everything before it reaches you. VOCABOTICS LTD, registered in England and Wales (no. 17412438).
