Office guide
Perpetual Office or Microsoft 365?
Compare ownership model, feature updates, cloud services and device needs to identify the better fit.
Updated 2026-08-28 · 5 minute readThe better Office model depends less on slogans and more on how many people, devices and cloud services you actually need.
Perpetual desktop licensing
A perpetual Office release is a one-time purchase for a specific version and licensed scope. It can be a good fit for a stable Windows or Mac computer that needs classic desktop apps without recurring feature upgrades.
Microsoft 365 subscription
A Microsoft 365 subscription typically combines continually updated apps with cloud storage, collaboration features and account-based use across supported devices. Access depends on an active subscription.
