Imagine equipping your business or home office with the definitive suite of professional-grade applications, paying once, and using them for the lifetime of your computer. That's the enduring value of Microsoft Office 2021 Home & Business. This is not a fleeting subscription that drains your budget monthly; it's a classic, one-time purchase Retail license granting you perpetual use of the essential tools that power modern commerce: Word, Excel, PowerPoint, Outlook, and OneNote. Designed specifically for professionals, freelancers, and growing small businesses across the EU, this suite provides a stable, familiar, and offline-capable software environment. It's the ideal choice for those who value predictability in their software costs and require a robust, compliant platform for everything from drafting critical contracts and analysing financial data to managing client communications and delivering compelling presentations.

What's included with your purchase
When you purchase Microsoft Office 2021 Home & Business from Lizensa, you are securing a complete, genuine, and fully compliant software solution. Your purchase includes a unique product key for a Retail license, which is the most flexible consumer and small business license type. This grants you a perpetual (lifetime) right to use the software on one Windows PC, with the ability to transfer the license to a new device if your original computer is replaced. You will receive a clear, step-by-step activation guide and a link to download the official installation files directly from Microsoft's servers, ensuring you get a clean, unmodified version of the software. A detailed, compliant VAT invoice is provided with every order, essential for your business accounting. The software is compatible with Windows 10 and Windows 11 and is available in multiple languages, including English, German, French, Dutch, and Polish. Activation requires a one-time internet connection to validate your key with Microsoft's licensing servers.
Office versions compared — which one should you buy?
Choosing the right Office version is crucial for your workflow and budget. The primary decision is between a one-time purchase like Office 2021 and a subscription-based Microsoft 365 plan.
One-time purchase (Office 2021 Home & Business): This is a "locked-in-time" version. You pay a single upfront cost and receive security updates but no new feature updates. It includes the classic desktop apps (Word, Excel, PowerPoint, Outlook, OneNote) for one PC. It's the superior choice for users who prefer a stable, unchanging toolset, do not need cloud services like 1 TB of OneDrive storage, and want to avoid recurring payments. It's ideal for managed IT environments that require strict application version control.
Microsoft 365 subscription: A subscription provides always-up-to-date applications with continuous feature updates, along with significant cloud services like 1 TB of OneDrive storage per user and Skype minutes. It's licensed per user across multiple devices (PC, Mac, tablet). This model is best for users who always need the latest features, work across multiple devices, and heavily utilise cloud storage and collaboration.
This specific edition, Office 2021 Home & Business, is the definitive choice for small business owners, freelancers, and home office professionals who need the core business applications—crucially including Outlook for professional email—without the ongoing cost of a subscription. It is a step up from Office Home & Student, which lacks Outlook and does not have commercial use rights. For enterprises needing database (Access) and desktop publishing (Publisher) tools, the Office 2021 Professional Plus edition would be the next tier to consider.
System requirements / compatibility
To ensure a smooth and responsive experience, your Windows PC must meet the following minimum specifications. These requirements are for the standard desktop installation of Microsoft Office 2021 Home & Business.
Operating System: Windows 10 or Windows 11. The suite is not compatible with Windows 8.1 or earlier versions, nor with macOS.
Processor: A 1.1 GHz or faster, dual-core processor is required. For an optimal experience, especially with large Excel datasets, a more powerful processor is recommended.
Memory (RAM): 4 GB is the minimum requirement. For professional multitasking and handling complex documents, 8 GB of RAM is strongly recommended.
Storage Space: A minimum of 4 GB of available disk space is required for the full installation.
Architecture: The installer supports both 32-bit and 64-bit systems. The 64-bit version is automatically installed on compatible systems to leverage more memory for demanding tasks.
Internet Connection: An internet connection is mandatory for the initial license activation. After activation, the core applications function fully offline.
Language Support: This product is available for installation in English, German, French, Dutch, and Polish.
Note: These specifications represent the core requirements. Exact requirements can vary slightly based on the specific configuration and installed updates. We always recommend validating against the official Microsoft documentation for your specific deployment scenario.
Installation and activation
Getting started with your new Office suite is a straightforward process designed for immediate productivity. After your payment is securely processed, you will receive a confirmation email containing your unique 25-character product key and a direct download link. This email is typically delivered within seconds of purchase. You can also access your key and download link at any time from your secure Lizensa customer account.
To install, simply click the download link to get the official Microsoft Office installer. Run the executable file and follow the on-screen prompts. When requested, enter the product key from your email. The setup wizard will then complete the installation. Upon first launch of any Office application, an internet connection is required for the online activation process, which binds the license to your device. Should you encounter any issues, our multilingual technical support team is available to provide free, expert assistance. Your Retail license allows for reinstallation on the same device if needed, and can be transferred to a replacement PC should your original computer fail or be retired.

FAQ — frequently asked questions
Is Microsoft Office 2021 Home & Business a subscription or a one-time purchase?
This is a classic, one-time purchase. You pay a single upfront cost and receive a perpetual license to use the software for the lifetime of your device. There are no monthly or annual fees, unlike a Microsoft 365 subscription.
What is a Retail license and how does it differ from an OEM license?
A Retail license is the most flexible type. It can be transferred to a new computer if your old one is replaced, and it includes direct support from Microsoft. An OEM license is typically pre-installed on a new PC and is permanently tied to that first device's motherboard, making it non-transferable.
How quickly will I receive my license key after purchase?
Our delivery is fully automated and digital. In the vast majority of cases, the email containing your product key and download instructions arrives in your inbox within 60 seconds of a successfully processed payment.
Is this a genuine, legal license for use in my EU business?
Absolutely. Lizensa sources all licenses from authorized European distributors. You receive a genuine Microsoft product key, a VAT invoice, and full compliance with EU consumer protection laws, making it perfectly legal for commercial use in your business.
What should I do if I have trouble with the activation process?
If you encounter an error during activation, first ensure you are entering the key correctly and that your PC has a stable internet connection. If the issue persists, contact our free multilingual technical support team. We can diagnose the problem and guide you through a resolution.
Can I reinstall Office 2021 on a new computer in the future?
Yes. Because this is a Retail license, you have the right to transfer it. If your current computer fails or you upgrade to a new one, you can uninstall the software from the old device and install and activate it on the new one using the same product key.
Does this version of Office work on a Mac?
No. Microsoft Office 2021 Home & Business is designed exclusively for Windows operating systems (Windows 10 and Windows 11). It is not compatible with macOS. For Mac users, the equivalent product is Office 2021 Home & Business for Mac.
What payment methods can I use?
We offer a wide range of secure payment options tailored for the European market. You can pay via credit/debit card, SEPA direct debit, iDEAL, BLIK, Google Pay, and more, all processed through our Stripe-secured checkout.
Do you provide a proper VAT invoice for my business records?
Yes, a detailed and compliant VAT invoice is automatically generated for every purchase. For B2B customers with a valid EU VAT ID, the invoice will be processed under the reverse-charge mechanism where applicable.
What is your refund policy?
We offer a 14-day right of withdrawal in compliance with EU consumer protection law. If you have not yet activated or downloaded the software, you are eligible for a full refund. Our support team can clarify the process for your specific situation.
Which specific applications are included in this "Home & Business" edition?
This edition includes the full desktop versions of five core applications: Microsoft Word, Excel, PowerPoint, Outlook, and OneNote. It is the entry-level commercial-use license that includes the Outlook email and calendar client.
Can I use this license for my home office and my small business at the same time?
Yes. The license is for one primary user on one device. The "Home & Business" designation explicitly permits both personal and commercial activities on that single installation, making it perfect for a freelancer or a home office that serves a registered business.
