How to Send Invoices From Your Phone the Moment an HVAC Service Call Ends
The fastest way to get paid is to invoice before you leave the jobsite, while the work is still fresh and the customer is standing right there. R-Pro gives you two powerful tools that work as one: a field app that lets you issue a receipt or invoice from your phone on the spot, and an office ERP that turns those field invoices into clean accounting and proper tax invoices — no double entry, no end-of-day catch-up.
Invoice on site, straight from your phone
- Finish the job, pull up the customer, and issue a receipt right there — no laptop, no back-office trip, no waiting until you're home.
- Scan the equipment nameplate and any parts receipts so model numbers and line items auto-fill instead of being typed out with cold hands.
- Pull the customer's full service history on the spot, so the invoice reflects exactly what was diagnosed and repaired on this visit.
- Works fully offline — in a mechanical room or rooftop with no signal, you can still create the invoice and it syncs the moment you're back online.
- Hand the customer a clear, itemized receipt before you pack up the van, which is the single biggest thing that gets you paid faster.
The office ERP turns that field invoice into real books
- Every on-site invoice flows into proper invoices and tax invoices in the office side — formatted, numbered, and ready to send or print.
- Set your OWN country's tax — name it VAT, GST, or sales tax and set your own rate, so the invoice is correct wherever you operate.
- The sale lands in your accounting automatically alongside purchases, expenses, and net profit, so your books are current without a bookkeeping session.
- Track who has paid and who hasn't through the customer ledger, instead of guessing from a pile of paper receipts.
- Pull reports on revenue and outstanding invoices whenever you need them — the office tool is a full ERP, not a stripped-down add-on.
One workflow: field and office, together
- What you capture in the field — the job, the parts, the receipt — becomes the invoice in the office with no re-typing and no double entry.
- Because both tools share one record, an invoice sent from the jobsite is already reflected in your accounting before you reach the next call.
- Diagnosis, repair steps, scanned parts, and the on-site receipt all stay attached to the same customer, so the invoice and the work history never drift apart.
- One subscription covers both the field app and the office ERP in 10 languages, so the tech and the office are always looking at the same numbers.
- The result is a clean loop: invoice at the curb, get paid sooner, and your books update themselves — field and office working as one.
Invoice at the curb. Let the books keep themselves.
R-Pro pairs a field app that invoices from your phone the second a job ends with a full office ERP that turns it into clean accounting and tax invoices — two powerful tools, one workflow.

Can I really send an invoice from my phone before I leave the jobsite?
Yes. The field app lets you issue a receipt or invoice on site the moment the job is done — pull up the customer, confirm the parts and labor (nameplate and receipt scans auto-fill the details), and hand it over right there. It works even with no signal and syncs once you're back online.
Is R-Pro a field app or an office program?
Both — they're two equal, powerful tools used together. The field app handles AI fault diagnosis, scanning, voice memos, service history, and on-site receipts. The office ERP handles invoices, tax invoices, accounting, inventory, suppliers, and reports. One subscription, one workflow.
Can I set the tax to match my own country?
Yes. You set your own tax name and rate — call it VAT, GST, or sales tax and enter the rate you charge. Your invoices and tax invoices come out correct for wherever your business operates.
Do I have to re-enter the invoice in the office later?
No. The invoice you create in the field flows into the office ERP automatically — no double entry. The sale posts to your accounting and customer ledger on its own, so your books are current without a separate bookkeeping step.
