Client Overview
A mid-sized manufacturing company operating across multiple plants in India was facing recurring challenges in inventory management. Despite having an ERP system in place, the client relied heavily on manual data entry, spreadsheets, and delayed stock updates. This resulted in frequent stockouts, excess inventory overruns, production delays, and working capital blockage. The client approached us for a mobile app development solution that could integrate IoT devices with real-time inventory visibility across warehouses and shop floors.
Business Challenges
The client is a mid-sized manufacturing enterprise operating in a highly competitive and cost-sensitive environment. With multiple production lines, warehouses, and a complex supplier network, efficient inventory management was critical to maintaining profitability and meeting delivery timelines. However, like many manufacturing organizations, the client was struggling with legacy processes that were no longer scalable.
Despite using a traditional ERP system, the lack of real-time visibility and mobile accessibility created significant gaps between physical inventory and system records. These challenges were common across the manufacturing industry, where rapid production cycles demand accurate, instant inventory data.
The manufacturing company faced several operational and financial issues:
- No real-time inventory tracking across raw materials, WIP, and finished goods
- Delayed stock updates causing production halts and emergency procurement
- Overstocking due to inaccurate demand forecasting
- Manual reconciliation between ERP, warehouse records, and physical stock
- Lack of mobile access for plant managers and procurement teams
The client needed a custom IoT-enabled mobile app that could provide live inventory data, reduce human dependency, and improve decision-making.
1. Lack of Real-Time Inventory Visibility
Inventory data was updated manually at fixed intervals, often at the end of shifts or days. This delay meant:
- Stock levels shown in systems did not reflect actual shop-floor reality
- Materials consumed during production were not immediately recorded
- Decision-makers operated on outdated information
Without real-time inventory tracking, production and procurement teams could not respond proactively, resulting in frequent mismatches between demand and availability.
2. Heavy Dependence on Manual Processes
Most inventory-related activities—stock entry, issue recording, reconciliation—were performed manually using spreadsheets and paper-based logs. This led to:
- Human errors in data entry
- Time-consuming reconciliation between physical stock and digital records
- High dependency on specific individuals for critical updates
The absence of a mobile app development solution made it impossible for staff to capture data instantly on the shop floor or in warehouses.
3. Frequent Stockouts Impacting Production
Stockouts were a recurring issue, especially for critical raw materials and fast-moving components. These shortages resulted in:
- Sudden production stoppages
- Idle manpower and machine downtime
- Emergency procurement at premium prices
The manufacturing unit lacked automated alerts or predictive insights, making inventory management reactive instead of preventive.
4. Inventory Overruns and Excess Stock
To avoid production delays, procurement teams often over-ordered materials as a safety measure. This resulted in:
- Excess inventory occupying valuable warehouse space
- Increased carrying and insurance costs
- Material aging, damage, and obsolescence
Without data-driven insights, the balance between availability and optimization was difficult to achieve.
5. Poor Coordination Between Departments
Production, procurement, warehouse, and finance teams worked in silos. Each department relied on different data sources, leading to:
- Conflicting inventory numbers
- Delayed approvals and misaligned planning
- Lack of accountability
The absence of a unified mobile app development and IoT platform prevented seamless collaboration.
6. Limited Mobility for Plant Managers & Decision Makers
Supervisors and managers had no mobile access to inventory insights. Critical decisions were delayed because:
- Reports were available only on desktops
- Real-time shop-floor visibility was missing
- Approvals required physical presence or manual communication
In a fast-paced manufacturing environment, this lack of mobility slowed down operations.
7. Scalability & Future Growth Constraints
As the company planned to expand operations, existing inventory processes could not scale. Challenges included:
- Inability to integrate new plants quickly
- No readiness for automation or Industry 4.0 adoption
- Increased risk of inefficiencies with growth
The client needed a future-ready mobile app development solution integrated with IoT to support long-term scalability.
Summary of the Challenge
The client’s challenges were not isolated issues but interconnected problems rooted in outdated inventory practices. The manufacturing industry today demands real-time data, automation, and mobile accessibility.
To overcome these challenges, the client required a custom IoT-based mobile app development solution that could transform inventory tracking into a real-time, automated, and intelligent process—laying the foundation for smart manufacturing and sustainable growth.
