In todays world of 2025 the computer field has changed computer services. Most IT companies had to reinvent themselves that don't write just custom software. Most applications are now online services rather than desktop and client server programs.
Online applications have become different where you use the application with a login account and pay to use the service. In other words, software applications have been placed on the internet.
I worked for a solutions provider that wrote custom software applications in Oracle, FoxPro and Visual Basic. Today, they developed a US customs clearance application where users to use all the time. This has provided a growing income stream for many IT companies.
Another example is an IT company offering advertising services all the time for users who pay. This has become the norm for most information technology companies.
