Tracking Parts Inventory Across Multiple Service Vans So Techs Stop Buying Duplicates
You run three vans, and last month two of your techs each bought the same hard-start kit because neither knew the other van already had two on the shelf. With R-Pro, the field app logs what each tech actually pulls on a job, and the office ERP keeps one shared parts count across every van — so the next tech checks stock before they swing by the supply house, not after.
On the van: log what gets pulled, the moment it gets used
- When a tech finishes a job — say a contactor swap on a 5-ton RTU — they record the parts used right on the customer's service record in the field app, so the count reflects reality, not a spreadsheet someone forgot to update.
- Scan the receipt from the supply house and the field app auto-fills the line items (part, qty, price), so a fresh box of TXVs or run capacitors lands in the system without anyone hand-typing part numbers.
- Scan the equipment nameplate on site and the model/serial attaches to the job, so when you reorder a specific OEM blower motor you know exactly which unit it was for.
- It all works fully offline — in a mechanical room with no signal, the tech still logs the part pulled, and it syncs to the shared count the moment the van is back in coverage.
- Per-customer history means if you go back to the same restaurant walk-in cooler, you see which parts that site already burned through this season.
In the office: one shared parts count, not three separate guesses
- The ERP holds a single inventory list across all vans and the shop shelf, so before a tech drives 30 minutes to the supply house, anyone can see Van 2 already has four of that part sitting unused.
- Purchase orders and supplier records live here, so reordering a low contactor or capacitor is a couple of taps against the vendor you already buy from — not a guess at last month's price.
- Every part used flows into accounting as a real cost against that job, so your net profit per call reflects actual parts spend, not a rounded estimate.
- Build an itemized quote or estimate that pulls from the same parts list and pricing, so the number you give the customer matches what your van actually carries.
- Invoices and tax invoices (with your own country's tax name and rate — VAT, GST, or sales tax) go out against the same job, so parts billed and parts stocked never drift apart.
Why duplicates stop: the field and office stay in sync
- Because the tech logs the part on the job in the field app, the office count drops automatically — no double entry, no end-of-week reconciliation where two vans both 'thought' they had it.
- One subscription covers every tech and every van, so all three vans report into the same shared inventory instead of each running its own private mental tally.
- When a part runs low across the fleet, the ERP shows it in one place, so you reorder once for the crew instead of three techs each grabbing 'just in case' stock.
- Field receipts scanned on the van and POs raised in the office update the same numbers, so the count an owner sees at the desk is the count a tech sees in the truck.
- Across 10 languages and any crew size, the rule is the same: a part is counted once, where it was actually used — so nobody buys what you already own.
Run your crew on R-Pro — field app and office ERP, working together
R-Pro is two strong tools in one subscription: a field app for AI fault diagnosis on 600+ real HVAC cases, nameplate and receipt scanning, and offline parts logging on every van — paired with an office ERP for shared inventory, purchase orders, suppliers, quotes, invoices, and accounting. Techs log parts where they're used, the office sees one shared count, and nobody buys a duplicate. Try R-Pro and stop paying twice for the same part.
Get R-Pro →FAQ
Two of my techs always end up buying the same part on the same week. How does R-Pro stop that?
Because both techs log parts used on the job in the field app, the office ERP keeps one shared count across all vans. Before the second tech buys, they (or you) can see the part is already on another van's shelf. The duplicate purchase only happens when nobody has visibility — R-Pro gives everyone the same number.
My techs are in basements and rooftops with no signal. Will the inventory still be accurate?
Yes. The field app is fully offline — a tech logs the contactor or capacitor pulled even with zero signal, and it syncs into the shared ERP count the moment the van is back in coverage. Nothing gets lost waiting for a connection.
Do I have to type in every part number when a box of stock arrives?
No. Scan the supply-house receipt with the field app and it auto-fills the line items — part, quantity, price. The stock lands in inventory without hand-keying part numbers, which is also how the count stays trustworthy.
Does parts spend actually show up in my numbers, or is it just a stock list?
It shows up in your books. Every part used is recorded against the job and flows into the ERP's accounting as a real cost, so your net profit per call reflects actual parts spend. The same parts list also feeds your itemized quotes and invoices, so billed parts and stocked parts stay aligned.
