An ERP for after-sales service teams.Designed to show at the first call whether the unit is under warranty or contract,dispatch a qualified technician and let technicians work offline in the plant room,and bill parts and labor separately for Thai tax.

A technician is sent first, then the argument about who pays begins.
How it's designed to workThe intake console finds the unit by phone number and shows warranty, contract, SLA and credit-hold badges before the request is created.

Two technicians go to the same machine.
How it's designed to workLinks a repeat report on the same unit to the existing request, with its status and appointment time.

Notes on paper, keyed in again later; data is lost and labor and parts do not match.
How it's designed to workThe technician app records on the device all day, replays safely without duplicates, and sends conflicts to the office.

A technician swaps a part for free and nobody approved it.
How it's designed to workAdded work needs the customer's signature, and amounts over the technician's limit go to a supervisor's approval inbox.

A fifth visit goes out under a four-visit contract and earns nothing.
How it's designed to workShows the remaining entitlement from the first call, and requires a quotation once it is used up.

Nobody knows which van holds what; counts are adjusted silently.
How it's designed to workTreats each van as a warehouse, refills by min-max, and requires a reason and approval for count differences.

Prototype screens in the Thai-language UI, with sample data.
The installed base with the full history of every repair, part and refrigerant used is at the center of every screen.
Warranty, contract or billable is decided before a technician is booked, not after the repair.
Coverage, SLA and work on the service side; price, billing cycle and remaining entitlement on the commercial side. No two places to maintain.
SLA is counted on the contract's calendar, paused only for reasons the contract allows, and escalated before it is breached.
Designed for recording on the device all day and replaying safely, with conflicts sent to a supervisor queue.
