You have probably used a SaaS (Software as a Service) app today without even thinking about it. Maybe you checked your email, had a video call, or worked on a shared document online. All of these are powered by SaaS applications. But what exactly are these tools, and what categories do they fall into?
So in this blog, we will walk through the main categories of SaaS applications. We will explain what each one does, give real-life examples, and help you understand why they matter. Whether you are just curious or planning to use them for your business, this guide will make it all super clear and easy to follow.
