The All-in-One App for the One-Man HVAC Contractor: Field and Office in One Subscription
When you run an HVAC or refrigeration business alone, you are the technician in the van and the bookkeeper at the desk. R-Pro gives you both jobs in one app: a powerful field tool for diagnosis, scanning, and on-site receipts, and a full office ERP for quotes, invoices, and accounting. Two strong tools, one workflow, one subscription.
In the van: a field tool that works the way a technician does
- AI fault diagnosis built on 600+ real HVAC and refrigeration cases — enter the symptom, get likely causes and concrete repair steps, not vague guesses.
- Scan equipment nameplates and supplier receipts with your phone camera; R-Pro reads them and auto-fills the details so you stop typing model numbers by hand.
- Record voice memos on site and keep a full service history per customer, so the last visit is one tap away when you walk back in.
- Issue a receipt to the customer right there on the job, before you leave the site.
- Fully offline — a basement plant room or a rooftop with no signal still works, and everything syncs once you are back in range.
At the desk: a complete office ERP, not a stripped-down notepad
- Build quotes and estimates — including itemized construction quotes — and turn an approved job into an invoice or a proper tax invoice.
- Set your OWN country's tax: name it VAT, GST, or sales tax and set the rate yourself, so the paperwork is correct wherever you work.
- Real accounting that tracks sales, purchases, expenses, and net profit — you see what the business actually made, not just what came in.
- Manage inventory, suppliers, and purchase orders, and keep a running customer ledger so you always know who owes what.
- Pull reports when you need them, whether for your own review or for tax season.
One workflow: field work flows into the books by itself
- The job you log on site — the customer, the service, the receipt — carries through to the office side, so you enter it once and only once.
- No double entry: finish the repair in the field tool and the revenue is already waiting in your accounting, not sitting on a paper slip in your glovebox.
- One subscription covers both the field tool and the office ERP — no juggling two apps, two logins, or two bills.
- Everything runs in 10 languages, so the same workflow follows you across customers and borders.
- Because field and office share one set of records, your customer history, your invoices, and your profit numbers always agree with each other.
One app for the whole business — field and office
R-Pro pairs a powerful field tool — AI diagnosis, scanning, and on-site receipts — with a complete office ERP for quotes, invoices, and accounting. Two strong tools, one workflow, one subscription.

Is R-Pro a field app or an office program?
Both, and that is the whole point. The field tool (AI diagnosis, nameplate and receipt scanning, voice memos, per-customer history, on-site receipts, offline) and the office ERP (quotes, invoices and tax invoices, accounting, inventory, suppliers, purchase orders, customer ledger, reports) are two equally capable tools used together in one workflow. You are not buying a field app with bookkeeping bolted on, or an accounting program with a thin job log — you get both, fully built out.
Can I set my own country's tax instead of being locked to one system?
Yes. You name the tax yourself — VAT, GST, sales tax, whatever applies where you work — and set your own rate. Invoices and tax invoices come out correct for your country, not forced into someone else's tax model.
Do I have to enter every job twice, once in the field and once in the office?
No. What you log on site — the customer, the service, the receipt — flows into the office side automatically. You enter it once, and the revenue shows up in your accounting without re-typing it at the desk.
Does the diagnosis and scanning still work where there's no signal?
Yes. The field tool runs fully offline, so AI diagnosis, nameplate and receipt scanning, voice memos, customer history, and on-site receipts all work in a basement plant room or on a remote rooftop. Everything syncs once you are back in range.
