Back end development: It comes into play when the user has interacted with the website interface via buttons and more. The main influencing factors in this phase are complex queries & data processing tasks.
Testing: It is vital to test every component of the software to prevent any possible bugs. Testing helps in knowing the end capacity of the software in real business conditions that may affect its costs in long term testing.
Software size: The software development costing is directly proportional to the size of the software and its user base. Its size is defined by the number of screens/pages it has and the size of the user base is defined by the number of end-users it is expected to adopt.
