Software as a Product

Software as a product (SaaP, also programming product, software product) is a product, software, which is made to be sold to users, and users pay for licence which allows them to use it, 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 a network.[1] Office 365, on the other hand, is an example of SaaS, where a monthly subscription is required.
