What is software vendor?
A software vendor (ISV), often known as a software publisher, is a company that focuses on creating and selling software rather than computer hardware for broad or specialised markets. In contrast, in-house software is created by the organisation that will utilise it, whereas custom software is created or tailored for a single, particular third party. Although ISV-provided software is used by end users, it remains the vendor's property. ISV-created software can be used for a wide range of purposes. Software for real estate brokers, healthcare personnel scheduling, barcode scanning, stock maintenance, gaming, commerce, energy exploration, vehicle fleet management, and child care management software are some examples.
