ERP is a central tool in the Business Information System. This management software is synonymous with performance, cost and resource optimization. But what is the definition of an ERP?

What is an ERP?

The term ERP comes from the English “Enterprise Resource Planning”. ERP has been translated into French by the acronym ERP (Enterprise Resource Planning) and is defined as a group of modules linked to a single database.

Concretely An ERP makes it possible to manage all of a company's operational processes by integrating several management functions : order management solution, inventory management solution, payroll and accounting management solution, e-commerce management solution, B2B or B2C trade management solution in one system.

In other words, ERP represents the “backbone” of a company. It uses a single database to store company information, allowing for better collaboration and better visibility into business activities.

To be qualified as an “Integrated Management Software”, an ERP software solution must cover at least two fundamental principles:

  • The integration of computer applications in the form of independent but perfectly compatible modules on a single and common database.
  • The use of a Workflow engine to define all the tasks of a process and to manage their implementation in all the modules of the system that need them.

ERP is a management software which allows the company to integrate various functionalities such as:

  • Accounting and financial management (accounting management ERP, billing management ERP),
  • Inventory management (ERP inventory management software),
  • Human resources management,
  • Supplier management (ERP for retail suppliers) as well as,
  • Sales management,
  • Distribution management or even,
  • E-commerce management (ERP commerce, specialized retail ERP).

In addition to an ERP, and as part of a customer satisfaction approach, many companies also use CRM software. This tool allows them to pool and maximize the knowledge of a given customer and, thus, to better understand, anticipate and manage their needs.

How does an ERP work?


An ERP brings together several applications to manage the operational and administrative activities of a company. It works by connecting the various departments of a company (accounting, human resources management, sales, production, etc.) and by providing a unified view of all company information.

The operation of an ERP generally follows several steps:

  1. Data collection : Data is collected from various systems and sources to be centralized in the ERP system.
  2. Data storage : The data collected is stored in a centralized database, which can be accessed by all departments of the company.
  3. Data processing : The data is processed in order to be usable by the various departments of the company.
  4. Data analysis : Data is analyzed to help decision makers make informed decisions.
  5. Reporting : Reports can be generated from collected data to help decision makers understand business performance.

Users can access the data and features they need for their work at any time, which can improve productivity and collaboration across departments.

The key components of an ERP system

ERP systems generally include the following modules:

  • Financial and accounting management: which allows you to manage company finances, invoices, accounts, budgets and tax returns.
  • Sales and purchase management: which allows you to manage customer orders, quotes, purchase orders, invoices and payments.
  • Inventory and operations management: which makes it possible to manage stocks, supplier orders, production operations and production plans.
  • Human resources management: which makes it possible to manage information on employees, salaries, leave and benefits.
  • Supply chain management: which allows you to plan and manage activities related to the supply chain, such as purchases, sales, and inventory.

What are the challenges associated with setting up an ERP system?

  • High cost: ERP systems can be expensive to set up and maintain.
  • Complexity: ERP systems can be complex to set up and use, which may require user training.
  • Customization: ERP systems may not be tailored to specific business needs, requiring additional developments.
  • Data migration: ERP systems generally require the migration of existing data, which can be a technical challenge.


In summary, ERPs are software that allows businesses to effectively manage their business and operational processes. They bring together data and processes from different departments in a business, such as accounting, sales, production, and human resources, to provide an overview of business activities. The benefits of ERPs include improving process efficiency, decision making, and data security. However, there are also challenges associated with setting up an ERP system, such as high cost, complexity, customization, and data migration. That's why it's important to choose the right ERP system for your business by evaluating your needs, comparing options, considering costs, and requesting demonstrations. A good understanding of ERP systems allows businesses to use them effectively to improve their operation and increase their overall performance.
