Unit register

Cold-chain service management
Every reefer you service, on one running record.
Job card, PDI checklist, warranty inspection report, parts and the GST invoice — one connected workflow instead of six disconnected registers. Built for refrigeration dealers and the fleets they look after.

Three jobs fell inside the window — those billed the claim. The one on 04 Aug did not, so it billed the customer.

The problem
A unit's history lives in six places. None of them talk.
Serial numbers in one register, warranty dates in another, job cards on paper, and the claim gets rejected because nobody can prove the install date.
How it usually runs
- Warranty claim stalls because the install date can't be proven
- Job card written on paper, then typed again for the bill
- Parts issued from stock, but nobody knows against which job
- AMC lapses quietly; you find out on the breakdown call
How it runs on Thermosyn
- Install date and warranty status sit on the unit, visible on every job
- The technician fills the job on his phone; the invoice draws from it
- Parts move against the job, and defective ones onto the warranty report
- Renewals and due services surface before the customer calls
Platform
Modules that already know about each other.
Raise a job from a unit, pull parts into it, send the defective ones to a warranty report, and bill the whole thing — without re-entering anything.
Warranty & AMC
Warranty status is worked out from the unit, not remembered. Every job knows whether it bills the customer or the claim.
Job cards & PDI
Assign, attend and close on the phone. The PDI checklist becomes the printed report — no second typing.
Parts & stock
Issue against a job, watch the stock ledger move, and raise a purchase order when it runs low.
Warranty reports (WIR)
Defective parts, labour codes and the claim itself — in the format the OEM expects, printable and emailable.
GST billing
Tax invoice or receipt with your seller details, GSTIN and place of supply, numbered from a gapless yearly series.
Unit lifecycle
Five stages. The record follows the unit through all of them.
Each stage inherits what the one before captured — which is why a warranty claim in year three can still show the PDI signed on day one.
In stock
Unit enters the register with its serial and component details.

Questions
Before you start the trial
Two groups. Refrigeration dealers and service centres who service reefer units, and the fleet owners whose vehicles those units are on. Both work on the same records, seeing only what concerns them.
Yes. Customers, vehicles and units import from spreadsheets. Duplicates are matched on registration, chassis and phone number rather than blindly added, so an existing customer does not become three.
Yes — tax invoices and receipts with your seller details, GSTIN and place of supply, CGST/SGST or IGST worked out from the state, and a number series that restarts each financial year without gaps or repeats.
Every job card, PDI report, warranty report and invoice carries one. Scanning it brings the reader to this site — a dealer can start a trial, and a fleet owner can reach their own vehicle records.
A single workshop is usually working the same day. If old records have to be cleaned and imported, allow a week — most of that is spent on the spreadsheets, not on Thermosyn.
It stays yours. Export customers, vehicles, units, jobs and invoices whenever you want, without asking us. Cancelling stops the billing; nothing is deleted until you say so.
