Custom software development is the process of designing, creating, deploying, and maintaining software for a specific set of users, functions, or organizations.In contrast to commercial off-the-shelf software (COTS), custom software development aims at a narrowly defined set of requirements. COTS targets a broad set of requirements, allowing it to be packaged and commercially marketed, and distributed. Customized software is software that is specially developed for some specific organization or another user. As such, it can be contrasted with the use of software packages developed for the mass market, such as commercial off-the-shelf (COTS) software, or existing free software.
