What is ERP? An In-depth Guide to Enterprise Resource Planning

Many people have questions about ERP: what is an ERP system? What does Enterprise Resource Planning mean in business? Why do you need an ERP system? What is the purpose of an ERP system? What is Simple ERP? What does ERP stand for? What is the price of ERP? What is the best ERP for distributors and wholesalers? What is ERP in finance? What is ERP workflow and payroll?

What is ERP Definition


It’s challenging to answer all these questions in one article. Here, we explain what is an ERP and how it helps business growth. ERP stands for Enterprise Resource Planning.

ERP is an integrated software application that standardizes and streamlines business processes to improve productivity, efficiency, and communication. An ERP system provides easy access to information for better business decisions. ERP integrates business processes across all functions, including accounting, finance, HR, purchasing, distribution, manufacturing, warehousing, inventory management, sales, and more. ERP systems work on a single database with standard data definitions.

ERP was first designed for manufacturing companies to improve operational efficiency. Now, all industries, including wholesale and distribution, retail, eCommerce (B2B and B2C), services, education, hospitality, healthcare, financial services, and government, use ERP systems to streamline business processes and stay competitive.

Evolution: A Brief History


  • 1960s: Early integration of business processes started with Inventory Control (IC) applications, developed in COBOL or Fortran. These helped track usage, set targets, manage replenishment, reconcile balances, and report status.
  • 1970s: Material Requirements Planning (MRP) applications appeared. MRP used the Master Production Schedule (MPS), Bill of Materials, and Inventory Records to schedule production orders and raw material purchases.

By the late 1980s, MRP expanded to include Financials, HRMS, Order Fulfillment, and Procurement. In 1990, Gartner coined the term Enterprise Resource Planning to describe applications integrating end-to-end business processes.

Over the next two decades, ERP systems expanded to Supply Chain Planning, Project Management, Customer Relationship Management, and Warehousing. This phase is called Extended ERP or ERP II.

ERP Finance

The finance module in an ERP system automates tasks performed by finance staff, including clerks, accountants, and managers. It ensures all transactions are accurately accounted for and reported automatically.

An ERP system workflow is a configurable sequence of activities in an ERP system. Modern ERP systems allow different user groups to customize workflows for their needs:

  • Configurable: ERP workflows allow multiple configurations, like different approval rules for invoices.
  • Extensible: Users can design unique workflows beyond standard ERP workflows, extending ERP capabilities across industries.

Payroll in ERP

ERP system payroll integrates payroll activities with overall business processes. It handles tasks like calculating pay, breaking down allowances and deductions, computing taxes, and transferring tax deductions to the government.

A good ERP payroll system also tracks loans and advances to employees and integrates payroll data with accounting for a complete process flow.

ERP Deployment Evolution


From the 1990s to 2010, ERP systems were mainly on-premise. Users owned the infrastructure.

From the 2000s, Cloud ERP became popular. The ERP system is hosted by a third-party vendor, reducing infrastructure costs and providing world-class security, automatic updates, and latest technology.

Newer ERP systems, called Post-Modern or Next-Generation ERP, use AI, Machine Learning, and Blockchain, supporting digital transformation.

Key Features of ERP

  • Enhanced data integrity
  • End-to-end visibility of operations
  • Single source of truth, eliminating data redundancy
  • Uniform look and improved user experience

Making ERP Successful

ERP success depends on user adoption:

  • Effective training
  • Optimal solution design
  • Simple and scalable configuration
  • High-quality documentation
  • Accurate data migration

ERP System Cost


The cost of an ERP system includes fixed, running, and hidden costs.

Fixed Costs

  • Infrastructure (for on-premise or hybrid ERP)
  • License costs (based on users)
  • Implementation costs (paid to system integrators)

Running Costs

  • Additional licenses for growth
  • IT team salaries
  • Stabilization costs (help desk support)
  • Support and maintenance (often included in cloud subscription)

Hidden Costs

  • Training and testing costs
  • Data migration
  • Change management
  • Implementation review

Types of ERP Systems


Based on Server Location:

  • On-Premise ERP: Customer maintains servers and support team.
  • Cloud ERP: Hosted by third-party vendors (AWS, Azure). Can be SaaS or PaaS.
  • Hybrid ERP: Combination of on-premise and cloud for gradual transition.

Based on Industry Size:

  • Tier I ERP: Supports large global enterprises. Examples: SAP, Oracle.
  • Tier II ERP: Supports mid-to-large companies, less global reach.
  • Tier III ERP: Supports small companies, initial step in ERP roadmap.

Avoiding ERP Failures


Common causes of failure:

Choosing a product based on cost rather than needs

Poor evaluation of requirements

Incompetent system integrators

Wrong or low-quality data (GIGO effect)

Poor localization (tax and compliance issues)

Lack of clear success criteria
