As answered by people managing Fieldpaid and Code Effects.
Fieldpaid's answer
Fieldpaid is built around two things no other contractor app combines: it runs directly on your existing QuickBooks item list — pulling your real prices to build quotes, then pushing finished invoices back automatically — and it shows you the real margin on every job after it's paid. You log the hours and materials you actually used, and when the invoice clears, Fieldpaid reveals your true profit versus what you quoted. Most tools tell you what you billed. Fieldpaid tells you what you actually made.
Fieldpaid's answer
Tools like Jobber and Housecall Pro are broad, expensive all-in-one platforms with scheduling, CRM, and dispatch you may not need — and they make you maintain a separate price catalog. Fieldpaid is deliberately narrow: it does invoicing, quoting, payment chasing, and profit visibility, and it uses the QuickBooks prices you already maintain instead of asking you to duplicate them. If you already run QuickBooks and just want to quote fast on site, get paid quicker, and finally see which jobs actually make money, Fieldpaid does that without the bloat or the price tag.
Fieldpaid's answer
Experienced solo and small-crew trade contractors — electricians, HVAC technicians, plumbers, and security integrators — with five or more years in business who already use QuickBooks Online. They know their prices and run a real operation, but lose money through invisible profit leaks and slow collections. They want a fast mobile layer on top of QuickBooks, not another full business platform to learn.
Fieldpaid's answer
Fieldpaid started from a simple observation: experienced contractors already have their prices dialed in inside QuickBooks, but QuickBooks is painfully slow to use on a phone at a job site, and it never tells them whether a job actually made money. The product was shaped with input from a working electrician who pushed it toward being QuickBooks-native rather than a replacement — read the item list, push invoices back, and stay out of the way. The goal was a tool that feels like "I handled it," not another system to manage.
Fieldpaid's answer
Next.js, React, Supabase (PostgreSQL), and Vercel, with the QuickBooks Online API for accounting integration and Stripe for payments.
