31 Jan 2024

Businesses are compelled to reassess their legacy tech infrastructure in the modern apparel retail industry. The outdated and unscalable ERP solutions pose a significant challenge and hinder accuracy, collaboration, and inventory control. The struggle intensifies with legacy systems, such as mainframes and servers, proving inadequate in the era of agility and cost-effective retail operations.

Modernizing your legacy enterprise resource planning (ERP) software helps streamline the process from start to finish. It helps you to innovate without disruptions and provides you with better opportunities to improve customer experience.

Explore how Rishabh Software helped a North American apparel company revolutionize its outdated legacy ERP system with a strategic approach to overcome scalability and usability challenges.

Project Overview

A North American apparel company, specializing in vintage-inspired custom apparel, faced growth constraints due to a legacy ERP system. The outdated system hindered ordering, design, production, shipping, accounting, and reporting. We undertook a phased modernization to overcome scalability and usability issues, revitalizing their operations. This transformation ushered an era of streamlined processes and data-driven decision-making with the apparel ERP system modernization.


Limited Functionality: The legacy ERP system was slow and struggled to handle the growing volume of orders, resulting in delays in order processing and shipment. It lacked the capability to sync with the evolving business requirements. The outdated ERP was also unable to leverage advanced data analytics to tap into the power of collective insights for real-time visibility and actionable insights.

Data Integration: The client desired seamless data flow between different departments and stakeholders for better visibility across the board. However, the legacy ERP system was unable to seamlessly integrate with standalone data components and modules, leading to manual data entry, errors, and discrepancies. Data and reports were stored in silos on an old data storage that was not accessible in real-time which often in either overstocking or inventory stockouts.

Security Vulnerabilities: The existing ERP system could be easily exploited as it had an outdated security architecture which made it vulnerable to evolving security threats.

Limited Mobility: Lack of real-time data access on mobile devices affected the sales team’s decision-making abilities.

Scalability Issues: The legacy ERP made it challenging to enter new markets because of its inability to scale up to meet the company’s expansion plans.

Outdated Reporting: Due to the outdated reporting capabilities of the system, it failed to deliver the comprehensive insights required for strategic decision-making.


Modernization of ERP solution for the apparel industry

Our team undertook a phased approach to address customer’s challenges. The engagement commenced with a Requirements Assessment (RA) phase to build confidence and identify areas of improvement. We helped recognize the need for change while embarking on a journey to ERP modernization. Here’s how they tackled the challenge:

Needs Assessment: The initial step involved a comprehensive needs assessment, including consultant collaboration and internal surveys, aiding in goal definition for the modernization of the ERP solution for the apparel industry.

Platform & Roadmap consulting: Drawing from our vast expertise, we advised the client to employ Microsoft Stack for enhanced scalability and integration. Leveraging Microsoft technologies, we added mobile access features and modernized the ERP with .NET Core and Angular.

Modernization & Customization with Technology Scaling: While the updated ERP system offered many out-of-the-box features, it still needed specific customizations to align the system with their unique processes. We consulted the client to choose Microsoft Azure as the go-to solution. Its suite of services ensured minimal disruption to ongoing operations while offering flexibility and scalability in accommodating the company’s evolving needs and aligning the ERP system with its requirements.
