Garage Conversion Gurus

The website, CRM and cost-calculator systems I built inside a trades business as it grew into a 2× Company of the Year — on organic enquiries alone. Most of this work lives behind the login, so this case study shows you the architecture, not screenshots. That's a feature, not an apology.

The challengewhere it started

A genuinely good trades business with the usual problem: enquiries arriving by phone, sticky note and memory. Quotes taking evenings. No system between "someone's interested" and "job booked" — which means leaks, and leaks cost jobs.

The brief I set myself: make the enquiry pipeline boringly reliable, so the business could grow on the quality of its work instead of the owner's memory.

What I built — the enquiry machinereconstructed architecture · not screenshots
The enquiry machine — a system schematic A website with local SEO, a cost calculator and enquiry forms feed into an integrated system I built — a CRM, quoting and follow-up automations — which together carried four million pounds in organic enquiries through to two Company of the Year awards. what goes in what I built what came out in_01 website + local seo in_02 cost calculator in_03 enquiry forms THE SYSTEM how it works crm — every lead logged quoting system follow-up automations integrated · client system £4m in organic enquiries no ads · no cold calls jobs quoted 2× company of the year every connector solid — nothing leaks between click and quoting

Every block above is something I designed and built from scratch, on a zero software budget. The connectors are the point: nothing between click and contract relies on anyone remembering anything.

The black box — what I won't show

Client data, quote values, lead sources, internal dashboards. I don't open clients' insides to win work — which is exactly the discretion you'd want if the next CRM was yours.

What went in → what came out

In: a website built for local search, forms tuned to qualify rather than just collect, a CRM shaped around how the owner actually worked, quoting that took minutes not evenings.

Out: £4m in organic enquiries carried without leaks, evenings back, and a business that looked — and ran — as good as its work.

Why no screenshotsBackend systems, client confidentiality, and a build that lives on machines I no longer have access to. The architecture above is the honest representation: drawn, declared, and accurate.
Almost nobody can show you the system behind £4m of enquiries — because almost nobody has built one.

The honest bitattribution, stated plainly

The £4m is the business's result — their trade skills closed those jobs. My part: I helped develop and evolve the brand, and I personally built the website, the CRM, the cost calculator and the automations that carried every one of those enquiries from first click to booked job without leaking. I won't promise you £4m. I will promise you the same plumbing, built properly.
