Challenge: A multi-branch bookstore was running on disconnected spreadsheets and a legacy POS, causing stock discrepancies, delayed financial reporting, and manual payroll errors across locations.Solution: Led end-to-end ERPNext implementation covering Inventory Management, POS, Finance & Accounting, HRMS, Warehouse Management, E-commerce Integration (Shopify + ISBN barcode sync), BI Reporting (Frappe Insights), and Production. Integrated UPI and Axis EDC payment gateways directly into the POS workflow. Conducted stakeholder workshops, converted requirements into technical specs, built custom modules, and ran full UAT before go-live.Outcome: Reduced stock reconciliation time by ~70%, eliminated manual payroll processing, enabled real-time sales dashboards across all branches, and achieved successful go-live within the agreed timeline with zero critical post-go-live issues.
