Why does a plumber need a custom business app?

A plumber typically manages jobs, quotes, invoices and payments through a patchwork of Excel, WhatsApp and paper. A custom app centralizes everything: scheduling, customer files, automated quotes, invoicing, payment follow-up. Average gain: 5 to 10 hours per week.

What's the delivery timeline?

Functional phase 1 delivered in 7 business days after scoping: interface, database for customers / jobs / quotes, and 2-3 critical integrations. Subsequent phases ship in short iterations.

Is there a mobile app for technicians?

Yes, available from phase 2. The mobile app (installable PWA or native) lets techs view schedule, access customer records, take photos, get customer signature and generate quotes on-site — even offline.

Which integrations are available?

Build Seven integrates the tools you already use: Google Calendar / Outlook, Stripe or GoCardless (payments), accounting (Pennylane, QuickBooks), SMS Twilio, e-signature (Yousign, DocuSign).

The problem

Excel, WhatsApp and paper
eat your evenings.

An average plumber handles 15 to 25 jobs per week. Quotes typed by hand in the evening, invoices sent as improvised PDFs, schedule on paper, manual follow-ups for late payments.

A custom business app replaces that patchwork with one single tool: scheduling, customer records with history, quotes generated in 30 seconds from a price catalog, invoices sent automatically, scheduled follow-ups. You get your evenings back.
