This SaaS licensing glossary is built for the people who actually sign and renew the contracts: mid market CFOs, IT leaders, procurement, and the SaaS and FinOps managers who carry the spend. Every entry is written in plain buyer language, free of vendor spin, so you can read a quote, question a line item, and protect the budget.
We group the terms the way overspend actually shows up. License waste sits in one place, plan and contract mechanics in another, and the rationalization concepts that remove duplicate tools in a third. Each definition links to the service line and the cluster pillar that put it to work.
License and seat terms
This is where most quiet overspend lives. Seats get bought and never deprovisioned, plan tiers drift upward, and nobody owns the cleanup. These definitions help you find and reclaim that money.
- License right sizing, matching every user to the lowest plan tier that still does their job.
- License reclamation, the repeatable process of finding inactive seats and pulling them back before the next renewal.
- Shelfware, paid software that is provisioned but barely used or never deployed at all.
- Plan tier, the packaged feature level you buy, for example Microsoft 365 E3 against E5, where the wrong choice is a recurring tax.
Contract and renewal mechanics
The contract decides how fast cost can rise and how easily you can cut it. Learn the mechanics before the renewal lands, not after.
- True forward, the Microsoft Enterprise Agreement mechanic that charges for added users at the next anniversary without crediting reductions.
- True up, the annual reconciliation that bills for licenses added during the term.
- Auto renewal, the clause that rolls a contract forward, often with an uplift, unless you give notice in a set window.
- Price increase, the uplift a vendor proposes at renewal that a usage backed case can blunt.
Rationalization and governance terms
Once the licenses are clean, the next savings come from removing tools that do the same job and keeping the stack disciplined.
- SaaS management platform, tooling that discovers applications, tracks usage, and surfaces renewals in one view.
- Tool sprawl, the slow accumulation of overlapping applications bought by different teams.
- SaaS consolidation, moving work onto a platform the company already owns, often Microsoft 365.
How to use this SaaS licensing glossary
Read the term, then follow it into the work. The full picture sits in the digital workplace cost optimization pillar, which ties Microsoft 365, collaboration, content and agreement tools, and renewals into one spend map. From there you can move into Microsoft 365 optimization, collaboration and video rationalization, SaaS renewal negotiation, license right sizing, tool rationalization, and SaaS management and governance.
