About

PlumbMargin is job costing and quoting software for UK sole-trader plumbers and very small plumbing businesses. It calculates labour, materials and overhead, and shows gross profit and margin before the quote is sent. The customer quote does not include internal costs. Three quotes are free and need no account. A one-time £49 licence removes that limit. There is no monthly subscription.

About

Wrencher is a Windows desktop app for sole traders and small trade businesses. It combines client records, quotes, job scheduling, alerts, invoices and mileage tracking. Users can prepare quotes with multiple options, convert quotes into invoices, and organize work in a week calendar. Intended users include electricians, plumbers, HVAC technicians, builders, landscapers and other tradespeople. The app runs on the user's computer after license activation, with no account, login or cloud service. It is for tradespeople who prefer local storage while managing quotes, scheduled jobs, client details, invoices and mileage in a desktop tool. Wrencher is offered for Windows. It has a 30-day full-feature trial and licenses at $99 per year or $299 for lifetime access. Its scope is day-to-day quoting and job administration rather than a broad field-service platform.

UK plumbers and small plumbing businesses

Audience

Sole traders and small trade crews (1-5 people): electricians, plumbers, HVAC technicians, builders, carpenters, painters, landscapers, and handymen. Especially useful for tradespeople who want to keep client data on their own computer instead of a cloud service, and who are tired of monthly subscriptions.
