Internal Management System Development for a USA-Based Automobile Spare Parts Manufacturer

Discover how our team assisted a leading USA-based automobile spare parts manufacturing and distribution company in developing a custom management system tailored to its internal process integration, automated reporting, and workflow automation needs. The system extended the capabilities of the company’s existing environment and enabled better management of orders, inventory, production, finances, and overall business operations.

Custom Internal Management System

Project Overview

A USA-based automobile spare parts manufacturing and distribution company needed to extend its existing environment to cover processes associated with finances, inventory management, production, sales, and logistics. Different facilities and business units had unique processes that needed to be managed without modifying the ERP environment.

A custom internal management system was developed around the existing ERP architecture. The solution connected custom applications, business data, reporting, and workflow automation through the platform's established APIs and business object framework.

Solution Delivered

A customized management system has been developed in order to integrate the ERP system with various applications, API integrations, reporting capabilities, and workflow automation.

Developed Custom Internal Applications

Custom applications were created for order management, inventory control, production planning, and other department-specific requirements. These applications worked with existing ERP business logic to support organization-specific spare parts manufacturing and distribution processes.

Integrated Business Systems

REST-based APIs and business objects connected the ERP environment with internal and external systems. Automated data exchange improved information flow across sales, procurement, inventory, production, and other operational functions.

Automated Financial and Operational Reporting

Reporting dashboards were introduced for sales orders, inventory, receivables, cash flow, production, and other operational indicators. Automated data retrieval reduced dependence on manually prepared reports.

Automated Business Workflows

Recurring processes across order management, purchasing, production, and inventory were streamlined through workflow automation. Defined business rules helped reduce manual intervention and maintain consistent process execution.

Built an Upgrade-Friendly Architecture

Custom functionality was developed around established APIs, business objects, and extension capabilities instead of modifying the ERP's core functionality. This made it easier for the system to accommodate future changes in the platform.

Role-Based Access Control Implemented

Role-based access control was configured for administrators, managers, and end users. Access control was possible at application, business information, reporting, and administration levels depending upon user responsibilities.

Developed Operational Dashboards

Custom dashboards provided visibility into sales, inventory, production, financial indicators, and operational activity. Teams could access relevant business information through a centralized interface.

Secured ERP Integrations

The solution incorporated authenticated API access, role-based authorization, encrypted data transmission, input validation, secure credential management, and audit logging to protect information exchanged between connected systems.

Architecture

Frontend (Custom Applications):

Based on the framework and provides web/desktop UIs for internal users. Features: custom order management dashboards, inventory control dashboards, production planning and scheduling dashboard, financial reporting and analytics dashboard, data integration and synchronization tools.

Backend:

Core logic with customizations. Business objects (self-contained business logic modules within the environment). Custom applications developed using the platform’s extension capabilities. Custom services support applications working with business objects.

Data Layer (Microsoft SQL Database):

The custom management system uses a Microsoft SQL database. The system-wide database stores operator, administration, and licensing information. The company database for each company stores transactional data in hundreds of tables.

Integration Layer:

REST-based APIs access data via a REST interface across functional modules, including inventory, production, procurement, sales, and finance. Business object APIs develop custom business applications via REST, SOAP, and WCF. Reporting APIs run and distribute documents programmatically.

Infrastructure:

Deployment flexibility – Cloud, On-Premises, or Hybrid. The architecture of the system is designed to support scalability and can handle multiple branches of international companies. Data storage that is safe with Microsoft SQL.
