Because each piece of software is custom-made and unique, it’s difficult to determine ageneral development cost for customised software. No two custom-built applications are alike. As a result, it’s difficult to share an estimate of general expenses without first learning about the project’s unique requirements.
The size of the programme (the number of pages/screens), the complexity of the software, conceptual design, interaction with some other systems, migration of current data, usage patterns, and so on; all contribute to the expenses of customised software creation.
