MS Office Professional Plus 2021
Microsoft's most complete standalone Office
Office 2021 Professional Plus is the most complete standalone Office suite for Windows, offered as a one-time purchase instead of a Microsoft 365 subscription.
Create documents, manage email, analyze data, build presentations, design publications and work with databases - all in a single suite you own for life.
All seven applications, including Access and Publisher
The Professional Plus edition includes Word, Excel, Outlook, PowerPoint, Access, Publisher and OneNote.
Access and Publisher are not part of the Home and Student or Home and Business editions, so Professional Plus is the choice when you need the full toolset.
Own it once, no subscription
This is a lifetime license, not a subscription. Pay one time and keep using Office 2021 without monthly or yearly fees.
It is ideal for business owners, home offices, remote workers, accountants, engineers, students, consultants and IT professionals who prefer owning Office to renting it.
What you receive after purchase
- Genuine Microsoft Office 2021 Professional Plus license key
- Download instructions
- Step-by-step installation guide
- Activation guide
- Lifetime access to your license inside your PCSalesOnline account
