Our repair shop handles a steady flow of damaged distribution transformers and I need a Windows-based desktop program that ties the whole workflow together. The software must open with an intake screen where I log each incoming unit—basic make & model data, KVA rating, reported fault etc. From there the system should guide the transformer through every stage of repair: • Repair process tracking – define job cards, assign technicians, attach test readings and spare-parts consumption, then mark the job ready for inspection only if all mandatory fields are closed. • Inspection scheduling – create Stage-1 and Stage-2 inspection slots, print or email call-letters, and store the inspector’s pass/fail remarks alongside test certificates. A dashboard view that shows what is waiting for which stage will keep the shop floor organised. • Billing & invoicing – once the second inspection passes, generate the delivery challan automatically, raise the GST-compliant tax invoice, and later update each invoice with receipt dates, partial payments and outstanding balances. Everything runs locally on Windows so performance is critical even when the network is down. A clean WPF or WinForms front-end connected to a lightweight SQL (SQLite or SQL Server Express) back-end would work well, but I’m open to your preferred Windows-friendly tech stack as long as the UI stays snappy and the database is easy to back up. Acceptance will be based on: 1. Installer (.exe or MSI) plus complete, well-commented source code. 2. Role-based log-in (storekeeper, technician, inspector, finance) with simple permission rules. 3. End-to-end flow test: create a dummy transformer, push it through repairs, inspections, challan, invoice and a payment update without manual data edits in the database. 4. Printable PDFs for challans, inspection reports and invoices that match our letterhead (template will be supplied). 5. Basic user/technical documentation so our in-house IT can maintain the system. If a future mobile or web view becomes necessary, code structure should not block that expansion, but the immediate requirement is a solid Windows desktop application that our workshop staff can start using right away.

Hi there, I can deliver a fast, offline-first Windows desktop application that cleanly manages your entire transformer repair lifecycle—from intake to final payment—without slowing down shop-floor operations. I propose a WPF (.NET) front end with MVVM architecture, backed by SQLite or SQL Server Express (your choice). This keeps the UI snappy, works reliably without network access, and makes backups as simple as copying a single database file. The codebase will be structured in clear layers (UI, business logic, data access) so future web or mobile extensions remain straightforward. Key modules will include: • Intake & job cards with mandatory field enforcement before inspection • Repair tracking with technician assignment, test readings, and spare-parts usage • Stage-1 / Stage-2 inspection scheduling with dashboards, call-letters, remarks, and certificate storage • Automatic challan and GST-compliant invoice generation after final pass • Payment tracking with partial receipts and outstanding balances You’ll receive: MSI/EXE installer + fully commented source code Role-based login (storekeeper, technician, inspector, finance) Verified end-to-end workflow demo as per your acceptance test Printable PDF challans, inspection reports, and invoices using your letterhead Clear user and technical documentation for in-house maintenance The goal is a practical, production-ready system your workshop can start using immediately.

This is a workflow integrity problem, not just a desktop build. Your shop needs a system that enforces process discipline from intake to billing, works offline without hesitation, and removes manual gaps that cause delays or errors. I’ve built Windows-based operational software where performance, data correctness, and role control directly affected daily throughput. 1 I will design a Windows desktop application with a clean, fast UI and a structured local database that tracks each transformer from intake through repair, inspections, challan, invoicing, and payments without data duplication. 2 I will enforce job-card logic so technicians cannot advance stages unless mandatory fields, test readings, and parts usage are completed. 3 I will implement Stage-1 and Stage-2 inspection scheduling with dashboards, call-letter generation, pass/fail logging, and certificate storage. 4 I will automate GST-compliant invoicing and delivery challans after inspection clearance, with partial payment tracking and outstanding balances. 5 I will deliver role-based access, printable PDFs matching your templates, an installer package, and documented source code structured for future expansion. I focus on reliability, clarity, and ownership. This will be built to run daily on the shop floor, not as a demo, and handed over cleanly to your internal IT team. Best Regards Amaan Khan. L
