TurboKast Studio · for agencies
Your clients ask for things you can't build in-house. We build them under your name, at a fixed price.
You already build their websites well. When a client wants online booking, a quote calculator, a portal, an integration or an internal tool, we build it for you, from £749, under your name or ours. You set the price your client pays and keep the difference. One person in Dundee, building it, testing it and handing it over.
What we build
- Online booking with a diary, deposits and reminders
- Quote and price calculators
- Job, rota and quote apps with a phone view for crews
- Order, voucher and deposit pages
- Automations: confirmations, chasers, invoices raised from finished jobs
- Joining up what the client already pays for: Xero, QuickBooks, payments, email, their website
- Client logins and portals, scoped job by job (we say so if one is too big for a single-job price)
We do not build or replace your websites, branding or social work, and if a ready-made app does the job we say so.
How a job starts
- Brief. A free 15-minute call, or send me what the client asked for.
- Written fixed quote, free, with a Scope and Success Criteria Schedule: what is built and how we both know it works.
- You accept by replying "accepted". We start once the Schedule is agreed in writing.
- Built and tested on a test version first. You have 5 working days to check it against the Schedule.
- Live, with a handover document in the client's accounts.

Not VAT registered, so the price quoted is the price you pay. Hosting and third-party fees are quoted up front. Refund and fix promises have conditions: they are in the written order terms that come with every quote, and those terms win over this page.
Your name or ours
White-label or named, as you prefer. You deal with me; your client deals with you. I do not contact your client unless you ask. How reselling works (your client's rights, who owns what, whose data it is) is written down before the first job.
Safe to resell
- Code, hosting and domain sit in your client's own accounts (or yours) from day one.
- When paid in full we assign the rights we own in the custom code. A handover document comes with every build, so any competent developer can take over.
- Written terms under Scots law. We build with AI coding assistants, directed by me, and every change passes automated tests; the terms say what we cannot promise.
- Professional indemnity and public liability insurance, no separate cyber policy. Details go in the quote.
Our proof: Green Palm Dundee Landscaping (named with their agreement). About seven staff; jobs, the rota and the quote calculator lived in three spreadsheets. We built one web app for the office and for crews on their phones, with invoices raised through QuickBooks. It is live and still growing. Public demo with made-up data, and the case study:

Honest limits. I am one person, and I do not yet have a named backup developer: the handover document is what protects you.
