Client Overview
Built on Precision.
Constrained by Paper.
Sar Auto Products Ltd. is a Rajkot-based manufacturer of high-precision automotive components — including synchronizer rings, cones, sleeves, hubs, gears, gearboxes, and power transmission assemblies — serving OEM and aftermarket customers across India.
With more than two decades of manufacturing expertise and advanced CNC and VMC machine-based production infrastructure, the company had built a strong reputation for dimensional accuracy and reliable delivery.
However, despite sophisticated manufacturing capabilities, the operational backbone remained heavily dependent on Excel sheets, paper-based workflows, and institutional knowledge held by key personnel. As production complexity increased, these disconnected systems began slowing operational efficiency, visibility, and decision-making.

Business Challenges
Operational Complexity the Spreadsheet Couldn't Contain
The problems were not isolated. They were deeply embedded across procurement, inventory, production planning, quality management, and reporting workflows.
Job-work and subcontractor movement lacked traceability
Management reporting required manual consolidation from multiple departments
No real-time inventory visibility across warehouses and production locations
Raw material inward and consumption tracking remained reactive
Production schedules existed in supervisor notebooks rather than centralized systems
Quality rejections and rework tracking were inconsistent
Machine breakdowns were handled reactively without preventive maintenance systems
GST, E-Invoice, E-Way Bill, and ITC-4 documentation processes were slow and error-prone
Transformation Objectives
What the Leadership Team Actually Needed
The leadership team was not searching for software. They needed operational control, visibility, accountability, and faster decision-making across the business.
The ERP transformation was designed around six strategic outcomes:
Real-Time Production Visibility
Track what is being produced, on which machine, at any moment — without relying on manual communication or verbal updates from the shop floor.
Proactive Maintenance
Shift from reactive breakdown management to preventive maintenance scheduling with structured downtime analytics and service history.
End-to-End Inventory Traceability
Track every lot from raw material inward through to finished goods dispatch with full lot-level history and serial number traceability.
Compliance Automation
Automate E-Invoice, E-Way Bill, ITC-4, and GST documentation workflows to eliminate manual errors and processing delays.
Subcontractor Accountability
Monitor job-work materials sent, received, and pending with automated challan documentation and ITC-4 compliance reporting.
Unified Management Dashboards
Provide leadership with a single operational source of truth across all departments, accessible in real time from any device.
Solution Overview
ERP Configured for Precision Manufacturing
A custom ERP was implemented as a fully integrated manufacturing-centric operational platform spanning nine functional modules. Rather than deploying a generic ERP structure, every module was configured around SAR Auto Product's operational workflows, approval hierarchies, manufacturing logic, and compliance requirements.
The objective was not simply digitization — it was to redesign operational flow, eliminate data silos, and create a connected manufacturing ecosystem where every department works from the same live data layer.
Solution Architecture
One System. Nine Modules. Zero Data Silos.
The ERP architecture established a connected operational flow — a centralized data layer accessible in real time across departments.

Before vs After
A Business Transformed, Not Just Digitized
"Before Setu, we were running a world-class factory on a patchwork of spreadsheets and verbal updates. We knew everything that was happening on the shop floor, but we could never see it all in one place, and we could never see it fast enough to act on it.
The transformation did not just give us better reports. It changed how we manage.
Our production team now works from live data. Our purchase team negotiates from documented history. Our maintenance team plans instead of reacts. And when our OEM clients ask for quality traceability, we can answer in minutes instead of days.
What Setu built for us is not a software system. It is the operational foundation we needed to grow to the next level."
Conclusion
Precision Manufacturing Deserves Precision Systems
SAR Auto Products Ltd. entered this transformation with deep manufacturing expertise and a strong growth vision. What limited scalability was not manufacturing capability, but operational visibility.
The ERP implementation restructured how the organization understands and manages operations by creating a unified operational system spanning procurement, inventory, production, maintenance, quality, and compliance.
The result was not merely software deployment. It was the creation of a scalable manufacturing command centre built for future growth.
