What is SaaS?
SaaS stands for Software as a Service: cloud-based apps you use over the internet, usually through a subscription. You don't buy and install the software on your own computers or servers. You just log in through a web browser.
Common SaaS examples include tools for accounting, project management and customer support. In the case of Taxually, the SaaS tool automates tax compliance. SaaS is popular because it scales easily, costs less upfront and stays up to date without manual upgrades. We cover this in more detail in 10 Automation Tools Every Business Needs.
