A full-stack field service app — GPS tracking, AI assistant, photo contracts, Stripe billing — built and deployed to Apple TestFlight in 18 days flat.
BuildBillRx operates a team of field technicians across multiple job sites daily. Scheduling happened over the phone. Job details were texted in group chats. Customer signatures were paper-based and impossible to track. Billing was manual and delayed.
The business was growing, but the operational chaos was growing faster. They needed a single system their entire team could use from a phone — and they needed it fast, before peak season hit.
The challenge: most app development timelines run 3–6 months minimum. They had 3 weeks.
We designed and built BuildBillRx — a full-stack mobile application for iOS and Android. The app handles every step of the field service workflow: job dispatch, GPS tracking, on-site documentation, photo capture, customer signatures, and invoice generation.
An embedded AI assistant helps techs fill out job notes, generate customer-facing summaries, and flag incomplete documentation before job close.
Stripe handles all billing. Clerk Auth handles team logins with role-based permissions. Supabase provides real-time sync across devices. Everything built on a 10-table PostgreSQL schema designed for scale.
Real-time technician location on a live map. Dispatch knows exactly where every team member is, at all times.
An embedded AI helps techs write job notes, generate customer summaries, and ensure documentation is complete before closing.
Capture before/after job photos, collect customer signatures on-device, and store everything permanently in the job record.
Generate and send invoices directly from the app. Stripe handles payment processing. Zero manual billing workflow.
Clerk Auth with custom roles — technicians, dispatchers, and admins each see only what they need.
Supabase Realtime keeps every device in sync instantly. Job updates, status changes, and new assignments appear in seconds.
BuildBillRx shipped to TestFlight in 18 days. The team onboarded in a single afternoon. Within the first week, dispatch time dropped significantly, job completion documentation went from inconsistent to 100% complete, and billing delays disappeared entirely.
The AI assistant became the highest-used feature — techs use it to dictate job notes hands-free and generate customer-facing summaries in seconds.
The system is now in daily production use across the entire team, handling dozens of jobs per day.
