This is a one-time, perpetual license for the core Office experience, delivering full versions of Word, Excel, PowerPoint, Outlook, and OneNote. It's designed for a single user on one Windows PC, licensed for commercial use, and built for those who value stability and outright ownership over a constantly changing subscription service. With digital delivery from Lizensa, you can go from purchase to productive in minutes, securing a genuine, EU-compliant license that will serve your business for years to come.
When you purchase Microsoft Office 2021 Home & Business ESD from Lizensa, you receive a complete, activation-ready package delivered digitally. This is a perpetual license, meaning it has no expiry date and is valid for the lifetime of the device it is installed on. The license is a Retail ESD (Electronic Software Download) key, tied to a single Windows PC and one user. You cannot transfer it to another machine after activation.
Your purchase includes:
Activation requires an internet connection. You simply download the installer, run it, and enter the product key when prompted. The software will then activate online, linking the license to your PC's hardware. The suite is compatible with Windows 10 and Windows 11, and the installer supports both 32-bit and 64-bit architectures where applicable.
Choosing the right Office version depends entirely on your work style and budget. The primary decision is between a one-time purchase like Office 2021 and a Microsoft 365 subscription.

Which apps are in this edition? Office 2021 Home & Business includes the essential productivity powerhouse apps: Word for document creation, Excel for data analysis and spreadsheets, PowerPoint for presentations, Outlook for email and calendar management, and OneNote for digital note-taking. It does not include Access (database) or Publisher (desktop publishing), which are part of the Professional edition.
Compatibility: Office 2021 uses modern file formats that are fully compatible with documents created in Office 2016, Office 2019, and Microsoft 365. You can seamlessly share files with colleagues and clients regardless of their Office version.
To ensure a smooth experience, your Windows PC should meet the following minimum requirements. For optimal performance, especially with large Excel datasets or complex presentations, a more powerful system is recommended.
Please note: These requirements represent a general guideline. Exact specifications can vary. We recommend verifying your system against the official Microsoft documentation before purchase.
Getting started with your new Office suite is a straightforward digital process designed for speed.
Reinstallation: Your license is tied to the device. You can typically reinstall the software on the same PC without issue, for example, after a hard drive replacement or OS reinstall. If you encounter activation problems, our free technical support team is ready to assist.
Securing a software license is an investment in your productivity, and the source of that license matters. At Lizensa, we have built our reputation on being the trusted, transparent partner for professionals and businesses across the European Union. When you buy from us, you are not just buying a key; you are buying certainty.
We ensure you can start working without delay. Our digital delivery system is engineered for speed, placing your genuine license key and download instructions in your hands within an average of 60 seconds after purchase. This instant access is backed by a commitment to authenticity. Every license we sell is sourced directly from authorized European distribution channels, guaranteeing it is 100% genuine and will pass any Microsoft validation check, now and in the future.
Your rights as a consumer and business buyer are protected. We provide a full, EU-compliant VAT invoice with every order, making accounting and tax reclamation simple. For B2B customers within the EU, a reverse charge mechanism is available. Your purchase is covered by the EU's 14-day right of withdrawal, giving you peace of mind. Our checkout is secured by Stripe, offering a wide range of payment methods including SEPA, iDEAL, BLIK, GPay, and major credit cards, all processed with bank-grade security.
Should you ever need help, our multilingual technical support team provides free, expert assistance with installation and activation questions.

This is a classic, one-time purchase. You pay a single upfront price and receive a perpetual license to use the software indefinitely on one PC. There are no monthly or annual fees, and the license does not expire.
A Retail ESD (Electronic Software Download) license, like this one, is purchased separately from the hardware and is tied to the user who activates it on their PC. An OEM license is pre-installed by a computer manufacturer and is permanently locked to the first machine it is activated on. The Retail ESD license offers greater flexibility as it is purchased independently.
Our system delivers your license key and download link via email almost instantly. On average, the email arrives in under 60 seconds. You can also access your key immediately in your Lizensa customer account.
Absolutely. Every license we sell is sourced through authorized European distribution channels. It is a 100% genuine Microsoft product key that will activate successfully and pass any online validation. You receive a valid VAT invoice, completing the legal chain of custody.
We provide free, multilingual technical support for exactly this reason. If you encounter any issues during installation or activation, simply contact our support team. We can guide you through troubleshooting steps or resolve activation blocks.
