MIISCOAI & Product Engineering

Field service ERP · Client product

An ERP and field-service app that take complaints from first call to paid invoice.

A custom ERP and a React Native field-service app built for Maheshwari Infotech, a consumer appliances enterprise. Customers raise complaints with photos and warranty details; technicians are dispatched, verify completion by OTP, pick repair parts and generate invoices — while the admin panel manages 500+ active customers and 1,000+ service complaints.

  1. The problem

    Service teams relied on manual calls and paperwork to coordinate complaint assignments, job verification and billing — causing delays and errors.

  2. The solution

    Built a role-based mobile app with structured complaint flows, an OTP handshake for job sign-off and in-app invoice generation.

  3. Key challenge

    Synchronising complaint state between customer and technician in real time while staying usable in low-connectivity field conditions.

  4. Outcome

    Reduced complaint resolution time and eliminated manual billing — a fully digital, end-to-end workflow on iOS and Android.

MIISCO / 02How it's engineered

The engineering behind it.

  • 01

    Workflow automation

    Complaint routing, technician dispatch and status timelines replace phone calls and paperwork.

  • 02

    OTP handshake

    Jobs are signed off by a one-time code exchanged between customer and technician.

  • 03

    Invoices that write themselves

    Parts, quantities and totals calculated automatically, exported as PDF and emailed.

  • 04

    Works in the field

    Offline-resilient mobile app that keeps state in sync when connectivity returns.

Maheshwari Infotech is business automation in practice: a manual, phone-driven operation turned into one digital workflow across an ERP and a mobile app.
