Software as a service (SaaS) is a licensing or subscription-based model which customers can access over the internet on any device. The software is centrally hosted in the cloud and there is no requirement for hardware to be installed by the customer.
Using this method has a number of benefits to consumers, whether that is individuals using software for private purposes, or businesses. Tasks related to accounting, invoicing, sales and communications can all be performed through Software as a Service.
The benefits of developing a SaaS application for your business, often mean users subscribe to the software, rather than purchase it, meaning you have a guaranteed revenue stream each month.
