The process of designing, building, deploying, and supporting software specifically for a group of users, tasks, or organisations is known as custom software development. Custom software development, as opposed to commercial off-the-shelf (COTS) software, focuses on meeting a specific set of needs.
Custom software integrations entail creating a solution that is unique to your particular use case. This code might range from a straightforward plugin to move data across databases to a fully developed, customised content management system.
