Introduction
Technology has changed dramatically over the past two decades. Businesses no longer need to purchase expensive software, install programs on every computer, or maintain complex infrastructure to access powerful digital tools.
Today, many organizations rely on Software as a Service (SaaS), a cloud-based software delivery model that allows users to access applications through the internet.
From email platforms and project management tools to customer relationship management systems and accounting software, SaaS solutions have become an essential part of modern business operations.
This guide explains what SaaS is, how it works, its advantages, challenges, and why it continues to shape the future of business technology.
