Which Version of Microsoft Office Should You Buy?

For most buyers the answer is Office 2024: it is the newest one-time-purchase Office and Microsoft supports it with security updates until October 2029. Older versions still work and cost less, but they no longer receive security updates.

Professional Plus vs Home & Business

Professional Plus is the most complete Windows edition, with Word, Excel, PowerPoint, Outlook, OneNote and Access (plus Publisher up to Office 2021). It activates with a product key and works on one Windows PC. Home & Business includes Word, Excel, PowerPoint, Outlook and OneNote with commercial-use rights, and is the edition to choose for a Mac. Its key is linked to your Microsoft account.

One-Time Purchase vs Microsoft 365 Subscription

Yes, you can still buy Microsoft Office outright. A one-time licence such as Office 2024 Professional Plus is paid for once and keeps working for as long as you use the PC. It receives security updates but no new features. A Microsoft 365 or Office 365 subscription adds new features continuously and covers several devices, but it must stay active. If you mainly write documents and spreadsheets on one PC, a one-time licence costs far less over a few years.

Multi-PC and Business Licences

Licensing a small team? The Office 2024 Pro Plus 3-PC licence and Office 2021 Pro Plus 5-PC licence keep every machine on the same version with one order and one invoice.

How Activation Works

1. Uninstall older Office versions and trials.
2. Download the official installer from the link in your order email.
3. Install Office, open Word and go to File → Account.

Microsoft Office Key FAQ

Can you still buy Microsoft Office as a one-time purchase?

Yes. Office 2024, 2021, 2019 and 2016 are all one-time purchases with no renewal fees. Office 2024 is the newest.

What is the best version of Microsoft Office to buy?

Office 2024 Professional Plus for Windows, or Office 2024 Home & Business if you need it on a Mac. Both are supported until October 2029.

Is a "lifetime" Office licence really lifetime?

A one-time licence never expires; the software keeps working on your PC indefinitely. What ends is Microsoft's support for that version, meaning security updates stop.

What is the difference between a product key and a licence?

The licence is your right to use the software; the product key is the code that activates it. When you buy a key here, you receive both.

Can I install Office on a Mac with a Professional Plus key?

No. Professional Plus is Windows only. Choose Office Home & Business for Mac.

Do I need a Microsoft account?

Not for Professional Plus, which activates with the key alone. Home & Business and Mac editions are linked to a Microsoft account.
