We Built a Contractor Quoting Tool in 48 Hours

A technical breakdown of shipping QuickQuote—the invoice app contractors actually want to use. In 2026, electricians in the UK are still writing quotes on the back of envelopes. Plumbers are texting invoice PDFs to clients from vans. HVAC engineers are emailing spreadsheets and hoping clients click the payment link before the WiFi cuts out. We built QuickQuote in two days to fix this. This is the story of how a small team at The BizLaunch Ltd shipped a production-ready contractor quoting tool using Next.js, Supabase, Stripe, and Resend—and what we learned along the way. The Problem: Friction at Every Step Contractors aren't slow to adopt technology. They're fast to abandon it when it doesn't fit their workflow. The pain points were clear: Quotes look unprofessional. Handwritten or auto-generated PDFs don't inspire confidence. Clients delay approval. Payment is friction. A quote email without a direct payment link means clients have to chase invoices, send bank transfers, or use Paypal
