Case Study
How We Built a Custom Billing & Service Management System — With GST Compliance and End-to-End Workflow Tracking
About the Ebby Electronics
An electronics service business handling:
- Repairs
- Spare replacements
- Customer service requests
With increasing volume, they needed a structured system to manage operations efficiently.
Problem
The business had multiple moving parts:
- Service estimation
- Repair tracking
- Spare billing
- GST and non-GST invoicing
But everything was:
- Manual
- Unstructured
- Difficult to track
Key Challenges
- No proper system for service estimates
- Difficulty managing GST vs non-GST invoices
- No tracking of products under repair
- No visibility of work assigned to technicians
- Billing and inventory not connected
- GST reports required manual intervention
The Real Issue
Operations were happening.
But there was no control, no tracking, and no compliance clarity.
Challenge
This wasn’t just billing software.
We had to build a system that:
- Handles end-to-end service workflow
- Tracks products from intake → delivery
- Manages both GST and non-GST billing seamlessly
- Integrates inventory into billing
- Keeps GST reporting clean and audit-ready
Solution
We built a custom service + billing management system tailored to their workflow.
1. Service Intake & Receipt System
- When a product is received:
- Receipt is generated
- Checklist captures:
- Accessories received
- Product condition
Ensures clarity and accountability from the start
2. Estimation System
- Separate estimates for:
- Service charges
- Spare parts
Structured and transparent communication with customers
3. Technician Assignment & Tracking
- Jobs assigned to:
- Internal technicians
- External service agents
- Agents can:
- Update service stages
- Track progress
Full visibility into who is doing what
4. Service Workflow Management
- Status-based system:
- Received
- In Progress
- Ready
- Completed
- When marked “Ready”:
- Admin gets notified
No need for manual follow-ups
5. Smart Billing System (GST + Non-GST)
- Toggle-based invoice generation:
- With GST
- Without GST
- Key Feature:
- Non-GST invoices do not affect GST invoice numbering
Ensures clean compliance
6. Inventory-Integrated Billing
- Spare parts billed within same invoice
- Inventory automatically updated
No mismatch between stock and billing
7. GST Reporting System
- GST invoices tracked separately
- Reports generated automatically
Ready to share directly with auditors
No manual reconciliation required
