Software as a product (SaaP) is software that is designed to be sold to users who pay for a license that allows the user to install and use the software on a personal device. This is in contrast to SaaS, where users buy a subscription and where the software is centrally hosted.
One example of software as a product has historically been Microsoft Office, which has traditionally been distributed as a file package using CD-ROM or other physical media or is downloaded over network. Office 365, on the other hand, is an example of SaaS, where a monthly subscription is required.
