The Best HVAC Estimate App for Building Quotes Right From Your Phone
Most estimating tools assume you're sitting at a desk. R-Pro doesn't. It pairs a field app you run on your phone at the job site with a full office ERP that handles your quotes, invoices, and books — two powerful tools working as one. You walk the equipment, build the estimate on the spot, and that same quote becomes an invoice and a line in your accounting without you typing it twice.
Build the estimate while you're still standing at the unit
- Scan the equipment nameplate with your phone camera — model, serial, and specs auto-fill so you're not squinting and re-typing numbers in a cramped mechanical room.
- Scan a parts receipt and the line items and totals drop straight into the estimate, so your material costs are real, not guessed.
- Pull up the customer's full service history before you quote — what you replaced last visit, what's still under warranty, what's likely to fail next — so the number you give them is informed.
- Drop a quick voice memo while your hands are dirty and convert it to text later, so nothing about the job gets lost between the site and the quote.
- It all runs fully offline. In a basement, on a rooftop, in a plant with no signal — you still build and save the estimate, and it syncs when you're back in range.
A real office ERP behind every quote, not just a PDF maker
- Produce clean, professional quotes — including itemized construction and installation estimates with labor and materials broken out line by line.
- Turn an approved quote into an invoice or a tax invoice in a couple of taps, with no re-keying of customer details or amounts.
- Set your OWN country's tax: name it VAT, GST, or sales tax and enter your own rate, so the totals are correct wherever you work.
- Track suppliers, purchase orders, inventory, and a running customer ledger, so the price you quote reflects what parts actually cost you today.
- See accounting that adds up on its own — sales, purchases, expenses, and net profit — plus reports that tell you which jobs and customers are actually making you money.
Field and office, one workflow — no double entry
- The estimate you build on your phone is the same record the office side works from — quote, invoice, and accounting all share one job, not three disconnected copies.
- When the field app captures a receipt or logs parts and labor, that cost flows into purchases and expenses automatically, so your books stay current without a second pass.
- Issue a receipt to the customer on site the moment the work is done — and that transaction is already reflected in your sales and ledger back at the office.
- Both sides run in 10 languages under one subscription, so a crew working across languages stays on the same numbers.
- The result: you quote in the field, you bill from the office, and the money is counted once — the day's work is already in the books before you've left the parking lot.
Quote in the field. Bill from the office.

Is R-Pro a field app or an office estimating program?
Both — and that's the whole point. The field app builds quotes, scans nameplates and receipts, and keeps customer history in your pocket; the office ERP handles invoices, tax invoices, accounting, inventory, and reports. They're two strong tools that share one workflow, so an estimate you create on your phone is the same record your office bills and books from.
Can I create a real, professional estimate on my phone in the field?
Yes. You build the full quote on site — itemized labor and materials, including construction and installation estimates — using nameplate and receipt scans to auto-fill the details. The customer gets a clean, professional quote on the spot, and you can issue a receipt right there once the work is done.
Can I set my own country's tax on quotes and invoices?
Yes. You set the tax name and rate yourself — VAT, GST, or sales tax — so your quotes, invoices, and tax invoices show the correct totals for wherever you operate, not a hard-coded rate from somewhere else.
Does the estimate work if I lose signal at the job site?
Yes. The field app is fully offline by design. You can scan equipment, build the quote, and save it with no internet — in a basement, on a roof, or inside a plant — and it syncs to the office side automatically once you're back in range.
