Project Overview
Project Overview
PI ERP is a comprehensive Payroll, HRMS, and Compliance platform developed for PI Jain & Co. to modernize payroll processing and statutory compliance for Indian businesses. It replaces spreadsheets and disconnected tools with a unified desktop application that manages payroll, attendance, leave, compliance, and operations — fully usable offline, with secure cloud synchronization when online.
The Challenge
The Challenge
Payroll in India is far more than salary calculations. Organizations must juggle attendance, leave, PF, ESIC, labour laws, multi-company structures, and inspections — often still on spreadsheets or fragmented tools.
- Complex Indian payroll: overtime, arrears, gratuity, bonus, and full & final settlements
- Statutory compliance across PF, ESIC, Factory Act, Shop & Establishment, and inspections
- Spreadsheets and disconnected systems create repetitive manual work and errors
- Consultants need reliable offline operation with future cloud synchronization
