Here are several differences between custom software development & off-the-shelf software solutions:
◉ Custom software development involves building software solutions from ground up. While, off-the-shelf software, on the other hand, is pre-built software designed to meet the needs of a wide range of users.
◉ Custom solution require a lot of research and time in development. Off-the-shelf softwares are designed for quick use and installation, hence, are faster to implement.
◉ Since custom applications are developed with unique features, keeping all aspects in mind such as application security, long-term viability and future-readiness, the cost may be higher than that of off-the-shelf software.
