Introduction

A leading retail chain with 110 stores was operating on an aging on-premise ERP (SAP ECC 6.0) that had served them for nearly 15 years. With the shift to omnichannel retail, the legacy system could no longer support fragmented data, poor scalability during festive peaks, or real-time analytics.

Business Problem

• Fragmented data across POS, online store, and warehouses, leading to mismatched inventory and lost sales

• Poor scalability during festive peaks (Diwali sales) causing downtime and delayed orders

• Lack of real-time analytics; management relied on daily summaries instead of live dashboards

• Time-intensive manual reconciliations across Finance, Merchandising, and Supply Chain 

• Limited customer insights preventing loyalty program management and personalized promotions

• Replace the legacy ERP with a modern, cloud-based, unified retail solution

• Enable real-time analytics for decision-making and forecasting

• Automate SKU mapping, sales reconciliation, and supplier workflows. Support seasonal scalability and peak-load stability

• Provide seamless integration of Finance, Retail, Warehouse, and CRM modules

• Drive adoption with strong training, change management, and hypercare support

• Migrating 8 years of historical data (sales & inventory) from SAP to Dynamics

• Managing 92 custom processes, re-engineering them to leverage Dynamics' native functionality

• Ensuring smooth adoption across 350+ employees in stores and back-office operations

• Balancing automation with flexibility for varied retail scenarios

• Maintaining scalability, security, and performance during festive sales peaks

• Unified Retail Platform: Migration from SAP ECC to Dynamics 365 F&O + Commerce

• Data Integration: ETL-driven migration of 8 years of historical data

• AI & Analytics: Azure Cognitive Services for demand forecasting; Power BI dashboards for real-time sales and inventory insights

• Automation: Automated SKU hierarchy restructuring and supplier workflows via Power Automate

• Change Management: Train-the-Trainer program, microlearning videos, and 24x7 hypercare support for smooth adoption

Technological Framework

Why these Setup?

Dynamics 365 F&O + Commerce provides a unified retail platform that eliminates data fragmentation across POS, online, and warehouse — while Power BI and Azure Synapse deliver real-time analytics replacing manual daily batch summaries.

Why this Setup?

Azure Cognitive Services-powered demand forecasting replaces manual planning, Power Automate eliminates manual reconciliations, and Viva Learning ensures 350+ employees adopt the new system confidently across 110 stores.

Why this Setup?

ETL-driven migration from SAP ECC and real-time integration with 110 store POS systems ensures inventory accuracy and a single customer view — enabling personalised promotions and loyalty management that the legacy system could not support.

Takeaway

Zapcom executed an 11-month phased migration to Microsoft Dynamics 365 for a 110-store retail chain — achieving 25% inventory accuracy improvement, 66% faster order fulfilment, 95% reduction in system downtime, and 16% improvement in customer retention.
