Every growing UK business eventually hits the same wall: the off-the-shelf tools stop fitting. The spreadsheet that ran operations in year one becomes a liability in year three. The CRM everyone uses is missing the one field that actually matters to your business. The "solution" ends up being three separate tools duct-taped together, a WhatsApp group, and one person who holds everything in their head.
Custom software replaces that mess with a single system designed around your real process — the one you actually run, not the one a SaaS vendor wishes you ran. It is more work upfront and far less pain forever.
What's included in a custom software build
The shape of a typical engagement. Every project is scoped individually — this is what we reach for by default.
Process discovery & mapping
We sit down (in person or on a call) and map the workflow you run today — every handoff, every edge case, every "we do this one weird thing". That becomes the spec.
Tailored data model
Your entities, your fields, your relationships. Not forced into somebody else's idea of a "contact" or "deal" or "project".
Modern tech stack
TypeScript, Next.js or Remix, Postgres, Prisma, role-based auth. Boring choices because they last. Hosted on a stack you actually own — no vendor lock-in.
Integrations with the tools you keep
Xero, HubSpot, Stripe, Google Workspace, Notion, Slack — anything with an API. Build once, sync forever.
Documentation & handover
Written admin docs, video walkthrough, and a one-page "how it fits together" diagram. So the system is not a black box the day we finish.
Post-launch support window
Thirty days of free bugfixes and small tweaks after go-live. Beyond that, a simple monthly support option if you want it — no lock-in contract.
Who this is for
- Founders whose operations are run out of a Google Sheet and a WhatsApp group that nobody dares delete.
- Teams paying for 4 or 5 SaaS tools that almost fit and spending more time in spreadsheets reconciling them than using them.
- Businesses with a process that is genuinely unusual and cannot be shoehorned into a generic CRM or project tool.
- Owners who want to own their data and their workflow — not rent it.
How we build it
Workflow discovery
One or two sessions mapping the current process, the painful bits, and the shape of the system that would replace it. Output: a written spec, not a 40-page wireframe deck.
Prototype & sign-off
Interactive prototype of the core screens and flows, reviewed with the people who will actually use it daily. Changes here cost nothing — changes after build cost a lot.
Iterative build
Short cycles with weekly demos. You use the real system on real data from week 2 onwards so feedback is grounded in actual use, not screenshots.
Migration & cut-over
We import your existing data, train the team, and run the new and old systems in parallel for a transition window so nothing breaks on day one.
Typical engagement ranges
Honest ranges, not a rate card. Every SoftwareYeah quote is tailored in writing after a free discovery call — these are the bands most projects land in.
Single-role dashboard, forms, reporting, a handful of integrations. Replaces one spreadsheet-and-WhatsApp workflow.
Role-based access, complex data model, multiple integrations, workflow automation, custom reporting. Replaces 3–5 SaaS tools.
Custom software pricing depends entirely on scope — a single internal dashboard is nothing like a multi-role operations platform. The ranges above reflect real SoftwareYeah projects; every quote is still confirmed in writing after discovery so there are no surprises.
