Enterprise software, also known as enterprise application software (EAS), is software used in organizations, such as in a business or government, contrary to software chosen by individuals (for example, retail software). Enterprise software is an integral part of a (computer based) Information System.

Services provided by enterprise software are typically business-oriented tools such as online shopping and online payment processing, interactive product catalogue, automated billing systems, security, enterprise content management, IT service management, customer relationship management, enterprise resource planning, business intelligence, human resource management, manufacturing, enterprise application integration, and enterprise forms automation.

Due to the cost of building or buying what is often non-free proprietary software, only large enterprises employ a software that models their entire business system.

As enterprises have similar departments and systems in common, enterprise software is often available as a suite of customizable programs. Generally, the complexity of these tools requires specialist capabilities and specific knowledge.
