RadiusOS — The operating system for your trades business
From first call to final payment —
one app for your whole business.
Track every job, follow up on every quote, and never let a lead slip through the cracks. RadiusOS keeps your pipeline organized so you can focus on the work.
Free forever. No credit card required.
Your estimates are in email. Your schedule is on paper. Your invoices are in QuickBooks.
Sound familiar? Most contractors lose jobs not because of their work — but because a quote never got followed up, or a call never got returned. RadiusOS puts everything in one place so you can run your business from your phone.
Every job. Every stage. One board.
The Field Service template is pre-built and ready to use the moment you sign up. Customize the stages for your workflow — or use them as-is.
Inbound call or inquiry logged
Estimate delivered, awaiting approval
Job booked on the calendar
Crew on-site or work underway
Work done, pending invoice
Invoice sent, awaiting payment
Never lose a lead from a missed call
Log every inquiry the moment it comes in — call, text, or web form. Every lead gets a health score so you know who needs a callback today and who can wait until tomorrow.
- AI scores every lead from 0–100 based on urgency and engagement
- See at a glance which quotes haven't been followed up
- Daily AI digest on your dashboard — no more forgotten callbacks
Follow up on quotes automatically
The job that falls through because you forgot to follow up on the estimate is the most expensive mistake in field service. RadiusOS tracks every open quote and tells you when to call.
- Auto-flag quotes that haven't been approved after 3 days
- AI writes a follow-up email for you — one click to send
- Set up sequences that remind customers automatically until they reply
Keep your schedule in one place
Move jobs from quoted to scheduled with a single drag. See your whole week at a glance. Add notes, log what was done, and track the next step — without leaving the app.
- Visual board showing every job by stage
- Drag jobs from Quote Sent to Scheduled in one move
- Notes and task reminders on every job record
Know what's waiting to be invoiced
Jobs that are complete but not invoiced are money sitting on the table. RadiusOS shows you exactly which jobs are done and need an invoice sent — so nothing slips through.
- Completed jobs are one stage away from invoiced
- See total job value by stage across your pipeline
- Reminders when completed jobs haven't been invoiced after 48 hours

Common questions
What is field service management software?
Field service management software helps contractors, HVAC techs, plumbers, electricians, and other trades professionals track jobs from first inquiry to final invoice. It replaces spreadsheets, paper schedules, and scattered email chains with one place for leads, quotes, scheduling, and payments.
Is RadiusOS free for HVAC and contractor businesses?
Yes. RadiusOS is free to start — no credit card required. The free plan includes the Field Service pipeline template, AI deal scoring, Gmail integration, and up to 250 jobs. Upgrade to Pro ($19/mo) for more jobs or Business ($39/mo) for unlimited jobs, automated follow-ups, and email sequences.
How does RadiusOS compare to ServiceTitan or Housecall Pro?
ServiceTitan and Housecall Pro are full field service platforms with dispatching, inventory, and technician routing — built for larger operations with $100+/month budgets. RadiusOS is for owner-operators and small crews who need the pipeline and follow-up tracking without the complexity or cost. Start free, no contract.
Can I track quotes and invoices in RadiusOS?
RadiusOS tracks the full job lifecycle — from first call through Quote Sent, Scheduled, Complete, and Invoiced. You can log notes, attach details, and use the AI-powered follow-up system to nudge customers who haven't responded to quotes. For full invoicing, you can integrate with QuickBooks or handle it separately.
