First coined by John Koenig back in 2005, SaaS is a business model that allows customers to pay to access cloud-hosted software applications over the Internet. Unlike traditional software models, you don’t need to purchase or install the software yourself. Instead, SaaS helps you access the software app through monthly or annual subscriptions.
