Fixed Price Software

Pricing

Predictable cost, predictable scope

A written specification with a fixed price attached — and a clean rule for anything that comes after.

How the price gets fixed

You tell us what you want built. We write a specification. The specification has a price tag attached.

The price covers everything inside the specification — design, build, testing, deployment, source-code handover. If something inside the spec turns out to take twice as long as we estimated, that's our problem, not yours.

If you ask for something outside the spec mid-project, we'll quote that separately, in plain English, before any work starts on it. You either approve the change order or you don't. You're never billed for work you didn't ask for.

What's not included

Honest list:

  • Hosting costs — Vercel, Supabase, etc. Usually a few pounds a month at the start; we'll set up the accounts in your name so you control billing.
  • Third-party services — Stripe fees, SendGrid / Resend usage, domain registration. All billed by the vendors directly to you.
  • Ongoing maintenance after handover. Optional retainer available; never an obligation.
  • Major scope changes mid-build. Handled as change orders.

Typical engagement sizes

Most projects sit in the £15k–£75k range and take 4–12 weeks from spec sign-off to handover. As rough guides:

  • £5–15k — single-purpose tools, internal forms, a clean marketing site with a CMS. 2–4 weeks.
  • £15–40k — client portals, dashboards, multi-page sites with auth and a small backend. 4–8 weeks.
  • £40–100k — fuller web applications with several user roles, payments, integrations, and a real domain model. 8–16 weeks.
  • £100k+ — multi-app suites, large integrations, or fixed-price rebuilds of existing systems. Bespoke quote.

These are starting points, not menu prices. The actual figure comes from your specification.

What you get for the money

Every engagement, regardless of size, includes:

  • A written specification you can take elsewhere if you don't want to proceed with us.
  • A GitHub repository with full source access from day one.
  • An architecture decision record explaining every non-trivial choice.
  • Code review and automated tests on every change.
  • Staged delivery with reviewable slices every two weeks.
  • Production deployment to your accounts, in your name.
  • Handover documentation, including the "what I'd do differently" conversation.

When you've paid the final invoice, you own everything outright — no licences, no ongoing tie-in, no holding the keys hostage.
