How to Track Parts and Stock as an HVAC Technician (Without Running Dry on a Job)
Running out of a capacitor, contactor, or the right gauge of line set halfway through a job costs you a return trip and a frustrated customer. Tracking parts well means two things working together: knowing what you pulled at the job site, and knowing what's left in the warehouse to reorder. R-Pro gives you both — a field app for the technician on site and an office ERP for the books and stock — two powerful tools running on one workflow.
At the job site: log what you actually used
- Record the parts you fit on each service call directly against the customer's job — capacitor, compressor, TXV, filter drier — so consumption is captured at the moment it happens, not from memory at the end of the week.
- Scan a supplier receipt or part nameplate with your phone and let R-Pro auto-fill the item details, so you're not typing model numbers with greasy gloves on.
- Issue a receipt to the customer on site listing the parts and labor, giving them a clear record and giving you a clean source for what left your van.
- Works fully offline — in a basement plant room or a rooftop with no signal, every part you log is saved and syncs later, so nothing gets lost.
- Tie each part to per-customer service history, so when you return to that site you can see exactly what was replaced and when.
At the office: real stock levels, suppliers, and reorder points
- Track inventory in the ERP so you always know what's on the shelf and what's down to the last unit before it bites you mid-job.
- Manage suppliers and raise purchase orders in the same system, so reordering common parts is a few taps instead of digging through old invoices.
- Record purchases against accounting automatically — every part you buy flows into your books as a cost, feeding sales, expenses, and net profit.
- Keep a customer ledger and pull reports to see which parts move fastest and what's tying up cash on the shelf.
- Set your own country's tax — VAT, GST, or sales tax with your own name and rate — so purchase invoices and tax invoices are correct wherever you work.
The connection: field use updates the office, no double entry
- Parts you log on a job in the field app flow into the office ERP automatically, so warehouse stock and the books reflect real consumption without re-typing anything.
- Because field and office share one data set, a part fitted on site can draw down inventory and land on the customer's invoice in the same motion.
- One subscription covers both tools in 10 languages — the technician's phone and the office computer stay in step, not in two disconnected spreadsheets.
- You stop guessing: what got used on the truck and what's left in the warehouse are the same story, which is what stops you running dry on the next job.
Stop running dry on the job
R-Pro pairs a field app — log parts, scan receipts, work fully offline — with an office ERP for inventory, suppliers, purchase orders, and accounting. Two powerful tools, one workflow, so what you use on site keeps your stock and books accurate automatically.

Is R-Pro a field app for technicians or an office program for inventory?
It's both, used together. The field app handles on-site work — logging parts used, scanning receipts and nameplates, issuing receipts, all offline. The office ERP handles stock levels, suppliers, purchase orders, and accounting. Field and office run on one workflow, so they're two equal tools, not one with the other bolted on.
Can I track parts on my van and parts in the warehouse?
Yes. You log what you fit at the job site in the field app, and the office ERP keeps your overall stock and reorder picture. Because the two share one data set, what you use on the truck draws down against what the office is tracking — no separate counts to reconcile.
Do I have to enter parts twice — once for the customer and once for inventory?
No. That's the point of the connection. A part you log against a job in the field flows into the office ERP automatically, so it can appear on the customer's receipt and reduce inventory from the same entry, with no double entry.
Can I set my own country's tax for purchase and tax invoices?
Yes. You set your own tax name and rate — VAT, GST, or sales tax — so purchase orders, invoices, and tax invoices are correct for wherever you operate, in any of the 10 supported languages.
