If you already understand what ERP is, why businesses implement ERP, and how to select an ERP system, you might think nothing is left to learn. However, before starting ERP implementation, one more important step remains. Organizations must clearly understand how to define the scope of work and identify the main modules of an ERP system.
Defining the correct scope ensures that the ERP system supports every important business process. Therefore, companies should carefully analyze their operational requirements before choosing an ERP solution.
How Organizations Define the Scope of ERP Work
To define the ERP scope, organizations usually discuss requirements with department heads (HODs) and process owners. These discussions help identify daily activities, reporting needs, and workflow dependencies.
However, another important question arises. How can a company find the right ERP vendor who can deliver the required solution?
To answer this, businesses must first understand how ERP systems are structured and how they manage large volumes of data in a centralized system.
For example, building an ERP system is similar to building a house. A house includes bedrooms, kitchens, living rooms, and bathrooms. Each section has a different function but still exists within one structure.
Similarly, ERP software consists of multiple modules. Each module performs a specific task while remaining connected to the central system.
Major Segments of ERP Systems
Most large ERP systems divide their modules into two primary segments:
- Commercial Modules
- Non-Commercial Modules
These segments help organizations manage operations efficiently.
Commercial Modules in ERP
Commercial modules directly affect the financial performance of a business. Therefore, management teams pay special attention to these modules.
Since businesses operate to generate profit, these modules play a critical role in monitoring revenue, expenses, and financial control.
Before implementing ERP, organizations should carefully analyze these modules and choose vendors capable of delivering reliable solutions.
Common commercial ERP modules include:
- Finance and Accounts (F&A)
- Sales Management
- Purchase Management
- Inventory Management
- Machine Spares and General Items
- Raw Material (RM) Stock Management
- Finished Goods (FG) Stock
- Import and Export Management
- Job Work Management
- HR and Payroll
- Statutory Compliance
These modules directly track financial transactions, inventory flow, and procurement activities.
Non-Commercial ERP Modules
Non-commercial modules also influence financial performance. However, they affect finance indirectly through operations, purchasing, and inventory activities.
Although they do not always handle financial transactions, they still play an essential role in business efficiency and productivity.
Common non-commercial ERP modules include:
- Operation Planning and Production
- Plant Maintenance
- Gate Entry and Exit Management
- Quality Control
- Research and Development
- Complaint and Customer Feedback
- MIS and Analytics
- Reports and Dashboards
- Roles and Access Rights
These modules help improve operational efficiency and decision-making.
Strategic ERP Modules
In addition to core modules, modern ERP systems often include strategic modules. These modules support business growth and strengthen relationships with customers and suppliers.
Although they may not directly generate financial transactions, they provide valuable data for strategic decision-making.
Popular strategic modules include:
- CRM (Customer Relationship Management)
- SRM (Supplier Relationship Management)
- SCM (Supply Chain Management)
- Logistics Management
Using these modules helps organizations improve sales performance and optimize procurement strategies.
Choosing ERP Implementation Phases
Once organizations understand ERP modules, they can decide which modules to implement first.
Many experts recommend starting with commercial modules, especially:
- Sales
- Purchase
- Inventory
Implementing these modules together ensures better data accuracy and operational control.
After achieving stable results, organizations can gradually implement Finance and Accounts.
Why Finance and Accounts Depends on Other Modules
The Finance and Accounts (F&A) module depends heavily on data from other modules such as Sales, Purchase, and Inventory.
Therefore, if these modules provide accurate data, businesses already achieve about 60% success in financial automation.
The remaining financial activities include:
- Banking transactions
- Cash transactions
- Payments and receipts
- Other accounting adjustments
Since these processes follow simpler business logic, organizations can manage them more easily once core modules function properly.
ERP Options for Businesses with Budget Constraints
Some organizations face budget limitations during ERP implementation. In such cases, they can implement only essential commercial modules first.
Additionally, many ERP systems integrate with financial applications like Tally. This integration allows businesses to manage financial data without implementing a full accounting module inside the ERP.
However, companies should consider one important limitation.
Some ERP solutions allow one-way communication with third-party accounting software. In this situation, data can move from ERP to the financial system, but changes made in the financial software may not reflect back in ERP.
As a result, tracking financial updates may become difficult in the future.
Conclusion
Understanding ERP modules and defining the correct scope of work plays a crucial role in successful ERP implementation. Organizations should carefully analyze their business processes, identify required modules, and choose a capable ERP vendor.
By implementing modules in the right sequence and ensuring proper integration, businesses can improve operational efficiency, financial control, and long-term growth.
