In-depth analysis of customized ERP functions: taking the "inventory management module" as an example

Inventory management is the core of ERP, and the difference in performance between the two in this module directly affects the daily operational efficiency of a company.

Customized ERP Function Analysis: Taking the Inventory Management Module as an Example to Explore the Differences Between Standardized and Customized Inventory Management Systems

How can a customized ERP system balance "rapid import" and "process flexibility" in its inventory management module? This article analyzes the challenges and limitations of both standardized and customized architectures.

Standardized Inventory Management: Quick Import and Data Format Restrictions

Packaged ERP systems have basic inventory management functions, which can meet the most basic needs of enterprises: purchasing, sales and inventory management.

  • Advantages: Quickly launch the system and meet the basic processes of most enterprises.
  • limit: The data format is fixed and not easily expanded or modified. This is problematic when companies have specific pricing strategies, complex multi-warehouse management, or require multi-dimensional reporting and analysis.Specific needsSometimes, the functionality of the suite system may not be sufficient, requiring manual intervention to address system deficiencies.

Customized Inventory Management: Challenges of Process Flexibility and Cross-Departmental Integration

Customized ERP systems can integrate a company’s unique purchasing or sales logic into the system.

  • Advantages: The process is highly flexible and can be precisely matched with business needs, further improving operational efficiency and saving a lot of manpower and time.
  • challenge: The development process is complex, and excessive customization can lead to system complexity, difficulty in upgrading, and increased long-term maintenance costs. Adherence to the developer's specifications and design principles during development may limit the system's long-term scalability.

Selection Guide for Small and Medium-sized Enterprises: 5 Key Considerations for Evaluating ERP Systems

When deciding to implement an ERP system, small and medium-sized enterprises (SMEs) should evaluate the following five key aspects based on their own circumstances and future development:

Five key considerations for SMEs when choosing an ERP system

From current processes, budget range, technical support to system upgrades, master the five key evaluation criteria for ERP selection in small and medium-sized enterprises.

Key Point 1: Assess the current state of the enterprise and the complexity of its processes (the higher the complexity, the greater the customization requirements).

The primary task is to identify needs and objectives. If a company's business processes are complex and unique, forming a distinctive source of its competitive advantage, then customization is more suitable. If the processes are simple, a standardized, versatile, packaged ERP system will suffice.

Key Point 2: Budget Scope and Total Cost of Ownership (TCO) Considerations

Customized ERP systems are expensive to implement and maintain. While packaged ERP systems have lower initial costs, their implementation and maintenance costs must be carefully considered.Total Cost of Ownership (TCO)Total Cost of Ownership (TCO) should include: initial investment, long-term maintenance costs, software upgrade costs, and user training costs. Please carefully evaluate the long-term costs.Hidden costsTo avoid unnecessary expenses.

Key Point 3: The System's Future Scalability and Resilience

As customers' business content continues to change and expand, the system must be able to keep up.

  • Set type: The system that offers "cloud modules" and "value-added applications" can be flexibly selected according to needs to meet future growth requirements.
  • Customization: It is necessary to ensure that future scalability is considered during the customization process to avoid the system needing frequent changes or rebuilds due to architectural limitations.

Key Point 4: Choose a reliable technology partner and training support

Choosing an experienced ERP implementation consultant is key to success. The technology partner should be able to:

  1. Understand customer needs and prioritize user experience.
  2. Provide system operation manuals, telephone customer service consultation, and on-site training to ensure that employees can understand how to operate the system.

Key Point 5: Commitment to Continuous System Optimization and Version Upgrades

The system requires regular maintenance and optimization. Packaged ERP systems should be updated regularly to maintain security, functionality, and compliance with the latest technological trends (such as AI and big data). Customized systems require maintenance contracts with technology partners to ensure continuous functional improvements and smooth interface operation.

Long-term strategy for ERP systems: considerations for maintenance, upgrades, and system transition

As businesses move towards digital transformation, many face a critical choice: continue using their existing customized ERP systems or transition to standardized suite ERP solutions? When system maintainers can no longer provide support and follow-up maintenance, businesses will face a bottleneck where the system can no longer be repaired, upgraded, or optimized, which forces businesses to develop new demands for ERP systems.

Why are companies shifting from packaged systems to customized systems?

1. Hidden costs and system maintenance risks

In the early stages of business growth, packaged ERP systems are favored due to their affordable price. However, as business expands, outdated and difficult-to-upgrade systems become common problems. Unmodifiable systems can create bottlenecks for businesses. These highly technology-dependent, fixed-process systems ultimately force companies to seek customized solutions.

2. Advantages of customized systems in terms of flexibility and stability

nowCustomization The ERP system adopts a modular architecture, allowing departments to select suitable modules based on their needs. It is highly scalable and can integrate with new technologies such as AI, BI reporting, and mobile apps. Regular updates further enhance its compatibility with the latest technological and cybersecurity requirements, providing advantages in flexibility and stability.

Four Steps and Strategy Recommendations for ERP System Transformation

When a company decides to shift from customization to packaged services, the following strategies are recommended:

Four Steps and Import Process for ERP System Conversion

By adopting the 80/20 rule strategy to implement the ERP system, we ensured a complete plan for data transfer, training, and post-launch tracking.

Step 1: Use balanced import (ERP Balanced Deployment Strategy)

This is the key to the transformation. Enterprises need to address specific workflows, report formats, and other aspects that cannot be fully implemented in a suite of systems. 20-40% demandIt can be done on the basis of the original logic.Secondary customization developmentThis design balances system stability with business flexibility.

Step 2: Planning for the transfer of legacy data and interface integration

Data transfer is a key risk point. Data structure cleanup and comparison are required, along with the provision of data conversion tools to transfer critical data (such as customer, supplier, product, and inventory information). Simultaneously, a two-way interface (API) between the original and new systems needs to be established to support the transition process.

Step 3: User Habit Transfer and Training

Employee resistance to new systems is a common challenge.A complete system operation manual, consultant training, online courses, etc. should be provided to ensure that users can adapt to changes in system functions, operating methods, and processes.

Step 4: Official Launch and Continuous Tracking

Implement the system in phases, gradually introducing modules rather than replacing everything at once. Retain some existing system operations for transitional support. After deployment, set KPIs to track performance (such as document accuracy and report generation time) to ensure the system achieves its expected benefits.

Customized ERP FAQs

Common ERP systems in Taiwan include local Taiwanese brands (such as Dingxin, Dingjie, and ICT) and international brands (such as SAP, Oracle, and Microsoft Dynamics 365), as well as cloud-based or open-source systems (such as ECOUNT and Odoo). Enterprises can choose the appropriate system based on their size, industry needs, and budget.

What is an ERP system? ERP stands for "Enterprise Resource Planning." An ERP system includes programs for all core business areas, such as purchasing, production, materials management, sales, marketing, finance, and human resources (HR). SAP was one of the first companies to develop standard software for enterprise solutions and continues to provide industry-leading ERP solutions.

The price of ERP systems varies greatly, mainly depending on the size of the enterprise, the required functions, and the model adopted (cloud or traditional buyout). Small businesses may only need tens to hundreds of thousands of New Taiwan Dollars, while large enterprises may need to spend millions or even tens of millions of New Taiwan Dollars. Cloud ERP is usually priced on a monthly fee basis, with relatively low costs (e.g., starting from about NT$1000 per month) and includes software maintenance fees; traditional ERP costs include expensive software licensing fees and server equipment fees, and additional system maintenance fees are also required.
