Get lifetime access to Microsoft Office 2021 or 2019 — pay once, own it forever. Choose Professional Plus for Windows (the full suite including Access and Publisher) or Home & Business for Mac. Both are perpetual desktop licenses.

This is NOT Microsoft 365. This is a one-time purchase — you own Office forever, with no subscriptions or recurring charges. Microsoft 365 is the annual cloud subscription ($99.99/year), whereas Office 2019 and 2021 are perpetual desktop licenses.
