The Challenge

PrecisionWorks, a 350-person precision engineering company in Pune supplying automotive components, was running production management on Tally (accounting only), Excel (production planning), and physical job cards. On-time delivery rate: 67%. Scrap rate: 4.2% with no traceability. Customer delivery complaints generated manually — no SLA tracking. SAP B1 evaluation had been abandoned due to ₹1.8 crore implementation cost and 18-month timeline.

Our Solution

Canny built a custom manufacturing ERP covering production planning (MRP), shop floor control with barcode-based job card scanning, quality inspection, inventory management, procurement, and customer order management. GST-compliant invoicing replaced Tally for operational data, with Tally retained for accounting via integration.

Technical Architecture

React frontend with Next.js

Node.js API server on AWS EC2 with PostgreSQL

Barcode scanning via React Native mobile app on shop floor tablets

Zebra label printers for barcode generation (ZPL)

Tally integration via Tally XML API for accounting sync

Redis for production scheduling real-time updates

“We looked at SAP Business One and Odoo. Both were either too expensive or too complex to configure for our actual production processes. Canny built exactly what we do — not a generic ERP we had to bend our processes to fit.”

— Rajesh Patil, MD — PrecisionWorks

Long-Term Impact & ROI

PrecisionWorks won two new Tier-1 automotive supplier contracts requiring demonstrable on-time delivery performance (>90%) — business they could not have bid on with their previous 67% OTD. Annual savings from scrap reduction: ₹90 lakh. Inventory reduction freed ₹1.2 crore in working capital.
