Buy Microsoft Office
Microsoft Office as a perpetual licence, with no subscription: Office 2024, 2021, 2019 and 2016 in the Standard, Professional Plus or Home and Business editions, for PC and Mac, plus Project, Visio, Outlook and Access sold separately. Key by email within 24 hours with an invoice, payment in CHF by TWINT or card. Not sure which version to pick? See the frequently asked questions.
Office 2024 is the latest and Microsoft supports it until October 2029. Office 2021 has been out of support since 13 October 2026, Office 2019 and 2016 since 14 October 2025: they still work, but without security updates. For everyday use, we recommend Office 2024.
Perpetual licence or Microsoft 365?
A perpetual licence is paid once: you keep the version you bought, which receives Microsoft updates until its end of support, but not new versions. Microsoft 365 is an annual subscription that always gives you the latest version and OneDrive storage. For steady office work, a perpetual licence costs considerably less over several years.
Standard, Professional Plus or Home and Business?
Standard includes Word, Excel, PowerPoint, Outlook and OneNote. Professional Plus adds Access (and Publisher up to the 2021 version). Home and Business contains Word, Excel, PowerPoint and Outlook in Microsoft's consumer edition, with a transferable Retail key or a PC/Mac key depending on the offer.
What do LTSC, Retail, Bind Key and phone activation mean?
LTSC is the Office edition for organisations, without the Microsoft 365 cloud services. Retail means a consumer key that is activated online. A Bind Key is linked to your Microsoft account, so you can reinstall Office from that account. A phone-activation key is activated through Microsoft's phone service: see the guide. The exact type is stated in each product name; LTSC keys require a confirmation at checkout.
Does Office work on a Mac?
Only the "for Mac" editions and the "PC/Mac" keys. The Standard and Professional Plus LTSC editions are for Windows only. See Office for Mac.
How do I install and activate Office?
Follow the installation instructions in the delivery email, then enter the 25-character key the first time you open an Office app (or under File > Account). Uninstall any other Office version or Microsoft 365 trial on the PC first, to avoid activation conflicts.
When will I receive my key, and what if it doesn't work?
By email, within 24 hours of payment, together with your invoice (please also check your spam folder). If the key does not activate, let us know within 7 days at support@chkey.ch: after checking, we replace it or refund you. Details: Shipping & Returns.
