Software delivered by a vendor as a service can help reduce
costs related to software acquisition. Although businesses
may find it easier to find the budget to acquire software as a
service (SaaS) instead of purchasing software outright, it may be
less clear as to what kind of license is appropriate.
Generally, software is delivered with certain limited rights to
copy and install software onto a computer. When purchasing
SaaS, there is typically no need to install a copy of the software.
Because there is no need to copy software, a traditional software
license with the right to copy and install the software is probably
not appropriate. Instead, when licensing SaaS, publishers
commonly select a right to use ("RTU") license.
