What is Enterprise Resource Planning (ERP)?

Enterprise Resource Planning (ERP) is business software that integrates core functions -- finance, procurement, inventory, HR, sales, and operations -- into a single unified system. ERP provides one source of truth for organizational data, helping businesses of all sizes automate processes, improve decision-making, and operate more efficiently.

Updated July 2026.

The global ERP software market was worth roughly $55 billion in 2024 and is forecast to reach about $123 billion by 2030 (Fortune Business Insights). Despite that scale, Panorama Consulting's 2024 ERP Report found the average ERP implementation still takes around 18 months -- a reminder that adopting ERP is as much an organizational change as a software purchase.

In this article we'll talk about the definition of enterprise resource planning (ERP) systems such as SAP, Oracle, Microsoft and Infor.

'Enterprise resource planning (ERP) is a method of using computer technology to link various functions—such as accounting, inventory control, and human resources—across an entire company. ERP is intended to facilitate information sharing, business planning, and decision making on an enterprise-wide basis.'

ERP solutions and systems monitor and help to execute day to operations throughout a business or organisation. They tie together different parts of an organisation including finance, warehousing, human resources, sales, project management and more into one centralised system.

By combining all of the different functions of a business in one system, ERP solutions can leverage a single data model and one single source of the truth. This means that data replication is eliminated and every employee within the business can access up to date information on sales, projects, finance, inventory levels and more. ERP systems help organisations to work in unison, by democratising critical information and providing it to all employees in real time.

Enterprise + Resource + Planning: what the term means

Breaking the phrase down explains the concept:

• Enterprise -- the software spans the entire organization, not a single department, connecting every business unit and location.
• Resource -- it manages a company's core resources: money, materials, inventory, people, and equipment.
• Planning -- it uses that shared data to plan, forecast, and coordinate activity across the business in real time.

Put together, enterprise resource planning means using one connected system to plan and manage all of an organization's core resources from a single source of truth.

What is the benefit of an ERP system?

As the name suggests, an enterprise resource planning tool helps an organisation to plan and deploy its resources more effectively. For many organisations with multiple lines of business or locations, an ERP tool is as essential as electricity connection - they simply can’t properly function without one. Organisations that don't run ERP solutions often experience huge inefficiencies and risks as they rely on communication via email, spreadsheets and one to one communication.

An enterprise resource planning solution enables business leaders to achieve a variety of business goals dependent on their needs, including improving profit margins, increasing sales or customer satisfaction and much more. By having one common data model and single source of truth, organisations can work more efficiently and with more agility. For a fuller treatment of the benefits of ERP — including the evidence on how much of that value companies actually realise — see our dedicated guide.

ERP Example:

Let’s consider an example: imagine a company which builds bicycles by purchasing components such as frames, pedals and handlebars from several suppliers. Without an ERP system, the procurement department would have to manually order these components, remembering to reorder parts when stock levels are low plus keep track of all deliveries. They would also need to keep some records of part numbers, costs and more. Similarly the shop floor workers would need to record how many bicycles they manufacture plus record wastage levels and ensure all bicycles despatched for shipping were also recorded. Meanwhile the finance team needs to ensure that all of this data is correctly logged and filed against the correct ledger.

If the finance team wanted to perform some analysis on the profitability of a particular bicycle product line, it would be a huge manual effort to find then consolidate the necessary data - and it would only be valid at that point in time, meaning they'd either waste several days every time they wanted to get that insight or they'd be operating without knowing whether they're making a profit or loss.

Whilst it’s possible to do all of this manually, an ERP system makes the collection, organisation and analysis of this information much faster and less prone to human error. If implemented correctly, an ERP would allow the bicycle company to run reports on any product line at any point in time - allowing them to quickly eliminate any efficiency gaps on the fly.

ERP Systems Can Automate Your Business

Modern ERP systems are also placing a much larger focus on not just logging and tracking tasks, but automating once manual processes. Using developments in machine learning and artificial intelligence, todays enterprise resource planning tools are capable of assisting and sometimes replacing humans. For example, many modern ERP solutions provide the ability to automatically scan PDF or paper purchase orders and invoices, converting them into a digital format and matching them without any need for human intervention. This allows for organisations to spend more time on value add tasks or to spend their time analysing the data within the ERP system to identify areas for improvement. ERP vendors are working on more use cases which take advantage of automation to increase the return on investment of implementing an ERP tool.

What modules does an ERP solution include?

Most ERP suites bundle a common set of modules -- financial management, procurement, inventory and supply chain, project management, asset management, sales/CRM, human capital management, and reporting and analytics -- and every vendor offers a different mix of depth and breadth.

For a full breakdown of each module and how to prioritise them, see our guide to ERP modules.

Who uses enterprise resource planning (ERP) systems?

Businesses in multiple industries use enterprise resource planning tools to help them operate more efficiently. Traditionally, ERP systems are associated with supply chain heavy organisations such as manufacturing and distribution. These businesses use ERP systems for financial management, but also procurement, supply chain, manufacturing and distribution. 

However in recent times, ERP systems have developed functionality which allows them to be used in other industries including legal, professional services, agriculture, software and information technology and more.  These organisations have a stronger focus on people and need to track metrics such as resource utlization, project management and profitability. This is also known as professional services automation.

In response, as well as modules for inventory and supply chain, many ERP systems of today place a greater focus on functionality required for people centric businesses including travel and expense management, timesheet recording, project management and accounting and human capital management. This functionality allows businesses in the services space the ability to deploy their resources - people more effectively.

What ERP systems are available?

ERP systems range from solutions built for small businesses to platforms for multi-billion-dollar corporations, and include both broad "horizontal" suites and industry-specific products. They also come in different deployment models -- traditionally on-premise, but increasingly Cloud ERP, where your vendor hosts, maintains, and upgrades the software for you.

For a side-by-side look at the leading products and who they suit, see our full list of ERP systems.

What is an ERP implementation?

ERP implementation is the practice or process of installing an enterprise resource planning tool within a specific organisation. Although most ERP solutions come with out of the box functionality across various modules such as finance, procurement, supply chain, professional services automation and more, an organisation will always have its specific way of operating and therefore the system has to reflect this - or the business needs to change. Due to this, ERP systems need to be implemented which is essentially a process of deciding and then activating ERP functionality according to a businesses specific needs.

How long does an ERP project take?

ERP implementations can take anywhere from a few weeks to a few years. How long an ERP project takes very much depends on how large your organisation is, what the ERP solution offers out of the box and how much each process needs to be customised. Typically, ERP projects take much longer and are much harder than most organisations anticipate due to the scale of preparation and change required to successfully complete one. This is also known as change management, which is something that many organizations neglect when thinking about changing their ERP systems.

Frequently Asked Questions

What is enterprise resource planning?

Enterprise resource planning (ERP) is business software that integrates an organization's core functions -- finance, procurement, inventory, HR, sales, and operations -- into one unified system with a single source of truth, so data is entered once and shared in real time across every department.

What is enterprise resource planning used for?

ERP is used to run and connect a company's day-to-day operations: recording financial transactions, managing purchasing and inventory, planning production and supply, tracking projects and people, and reporting on the whole business from one data set. It replaces disconnected spreadsheets and standalone tools with a single coordinated system.

What does enterprise resource planning mean?

The term breaks down into "enterprise" (spanning the whole organization), "resource" (money, materials, inventory, and people), and "planning" (using shared data to forecast and coordinate). Together it means managing all of a company's core resources from one connected system.

What is an example of enterprise resource planning?

A bicycle manufacturer using ERP can link procurement, the shop floor, and finance in one system: when components are used, stock levels, costs, and the general ledger update automatically, letting the finance team report on any product line's profitability at any moment instead of manually consolidating spreadsheets.

How is ERP different from MRP?

MRP (material requirements planning) is a narrower, older discipline focused only on production planning, inventory, and purchasing for manufacturing. ERP is broader: it includes MRP-style capabilities but also finance, HR, sales, projects, and analytics, unifying them across the entire enterprise rather than the factory alone.
