Logging Service on a Supermarket Refrigeration Rack So Each Case and Compressor Has Its Own History
A parallel rack in the back of a grocery store isn't one piece of equipment — it's four to six compressors feeding a dozen circuits that run reach-ins, multi-decks, walk-ins, and low-temp coffin cases, each with its own EPR, TXV, and defrost schedule. When the produce multi-deck floods back or the low-temp circuit short-cycles, you need to know what you did to THAT case and THAT compressor last visit, not a single blob of "service done at store #214." R-Pro's field app gives every case and compressor its own running history on-site and offline, while the office ERP turns that work into the quote, invoice, and parts accounting back at the shop.
On the Rack: Give Each Circuit and Compressor Its Own Log
- Set the supermarket up as the customer once, then log each visit against the specific circuit or compressor — "Circuit 3, low-temp coffin cases, replaced TXV" stays separate from "Compressor B, megohm low, replaced contactor" so histories never blur together.
- Scan the compressor and case nameplates with your phone — model, serial, refrigerant, and capacity auto-fill instead of you hand-copying a Copeland or Bitzer tag in a cold, dim back room.
- Lean on the AI fault diagnosis when a circuit acts up: feed the symptom (low-temp circuit short-cycling, multi-deck not holding temp, suction pressure hunting) and it walks symptom → cause → repair steps from 600+ real HVAC and refrigeration cases.
- Drop a voice memo while you're still on the roof or at the rack — "Circuit 5 EPR sticking, watch it next PM" — so the note lands on that circuit's history, not your memory.
- It all works fully offline. Mechanical rooms and walk-in basements kill signal, but the rack history, scans, and diagnosis run with no connection and sync later.
Back at the Office: Quote, Invoice, and Track the Parts
- Turn the rack work into an itemized quote — TXVs, EPR valves, contactors, drier cores, refrigerant by the pound, and labor hours line by line for the store's facilities manager to approve.
- Issue a proper invoice or tax invoice with your own country's tax set the way you need it — VAT, GST, or sales tax, your own name and rate — so a chain's accounts-payable desk accepts it clean.
- Track inventory and suppliers: that case of drier cores and the contactors you pulled off the truck draw down stock, and purchase orders refill them before the next rack PM.
- Watch real accounting on the job — sales against the parts cost and refrigerant purchases — so you actually know the net profit on a multi-store service contract, not just the revenue.
- Keep a customer ledger per chain or per store, with reports that show what each location has cost you in parts and labor across the year.
The Connection: One Visit, No Double Entry
- The service you logged at the rack — the circuit you touched, the parts you swapped, the hours you spent — flows straight into the office books. You don't re-key the visit into a separate accounting program.
- On-site receipts you issue at the store tie back to the same job that becomes the office invoice, so the field record and the billing record are one story, not two.
- Per-component history compounds over visits: next time Compressor B trips, last year's contactor swap and megohm reading are right there on its log, so you stop chasing the same fault twice.
- Both the field app and the office ERP run in 10 languages under one subscription — your roof tech and your office bookkeeper work in their own language on the same store, same rack, same numbers.
Two tools, one subscription — built for racks like this
R-Pro pairs a field app — AI fault diagnosis on 600+ real refrigeration cases, nameplate and receipt scanning, voice memos, per-component service history, on-site receipts, fully offline — with a full office ERP for quotes, invoices and tax invoices, inventory, suppliers, purchase orders, and accounting. Two equal tools that work together: log every case and compressor at the rack, and the work flows straight into your books. Available in 10 languages.

Can I keep separate histories for each circuit and compressor on the same rack, instead of one big store record?
Yes. You log each visit against the specific circuit or compressor under that supermarket customer. "Circuit 3 TXV replacement" and "Compressor B contactor" stay as distinct entries, so when one acts up you see exactly what was done to that component last time — not a blended store-wide note.
Will it work in the basement mechanical room and walk-in where I have no signal?
Yes — the field app is fully offline. You can pull up a circuit's history, scan a compressor nameplate, drop a voice memo, and run AI diagnosis with zero connection. It syncs once you're back in signal, and nothing is lost in the meantime.
How does logging rack service on-site turn into an invoice for the chain?
The work you log on the rack — the circuit, the parts, the hours — flows into the office ERP, where you build an itemized quote and issue an invoice or tax invoice with your own tax name and rate. No double entry: the field visit and the office billing are the same record.
Does it track the parts I burn through on a multi-store rack contract?
Yes. TXVs, EPR valves, contactors, drier cores, and refrigerant draw down inventory as you use them, suppliers and purchase orders refill stock, and the accounting side shows sales against parts and refrigerant cost so you see real net profit per store, not just revenue.
