A web application is very different from a standard business website. Instead of presenting information, it gives people something to interact with - whether that's managing projects, processing orders, collaborating with a team, or accessing software through a browser. As businesses continue moving more of their operations online, custom web applications have become part of everyday work rather than a niche technology investment.
