Find the load bearing part
One rule holds the money up. A landed price that must not move, stock that must not oversell, a tenant seam that must not leak. We name it on day one.
We take the one part of a build everything else leans on, write it first, and put it on a server with your own data behind it. You open the address and decide before anything else is agreed.
How we build
Not a status report. The commands, the tests, and the moment the thing first answers on a real address. Scroll and it runs.

No stub and no sample set. The real feed, the real tax table, the real register, so the first answer the thing gives is one you can check.
We build the obvious way beside ours and publish both numbers. The gap between them is the whole argument, and it is a fact rather than a promise.
A process supervising it, a database it reads from, a link in your inbox. You use it. That is the review.
No slides
Every build on this page sits on a server with a database behind it, at an address we send you. There is no deck to sit through and nothing to squint at, because a screen that cannot be clicked has not been proved to work.
The work
Every screen below is a photograph of the running build, taken from the build itself. Nothing here is a mockup.




Written, not assembled
There is no template underneath these. The pricing, the duty maths, the register lookup and the auction were written for the business they belong to, and every one of them has a test beside it that fails when it is wrong.
Measured, not asserted
Any studio can say a system is safe or fast. On these builds the claim is a figure from a run you can repeat in your own browser, printed next to what the ordinary approach produced.
What happens next
Not the whole brief. The one thing you already suspect is going to be hard. That is the piece we would build first anyway, and it is the piece that tells you whether to carry on.
