Field Service App questions
Can technicians use the app without signal?
Yes. Jobs, checklists and photos are saved on the phone and sync automatically when the technician is back online, which matters in basements, attics and rural areas.
Can customers book jobs themselves?
Yes. The customer app lets people request a visit, choose a time window, approve quotes and pay invoices, and every request lands in your admin panel.
Does it work for roofers as well as plumbers?
Yes. Checklists, photo steps, quote items and job types are set per trade, so a roofer, plumber, electrician or cleaning company each gets screens that match their work.
How much does it cost?
Our app plans are $3,000 for a Starter App, $5,000 for a Business App with accounts and an admin panel, and $8,000 for an Advanced App with a separate staff app, tracking and payments. Each plan is a fixed, one-time price.
Do you build for iPhone as well as Android?
Yes. We build in Flutter, so one codebase gives you an Android app and an iPhone (iOS) app. Every plan includes publishing on Google Play and the Apple App Store under your own accounts.
Who owns the app and the code?
You do. The app is published under your own Google Play and Apple developer accounts, the backend runs in your own Firebase project, and you receive the full source code at handover.
