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 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.
What is the difference between a Retail ESD license and an OEM license?
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.
How fast will I get my license key after paying?
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.
Is this a genuine, legal Microsoft license?
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.
What if I have trouble activating the software?
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.
Can I transfer the license to a new computer later?
No. A Retail ESD license for Office 2021 Home & Business is a single-device license. Once activated, it is permanently tied to the motherboard of that specific PC and cannot be transferred to another computer.
Can I reinstall Office on the same PC after a system crash?
Yes. The license is tied to the device's hardware. You can typically reinstall the software on the same PC, for example after reformatting your hard drive or reinstalling Windows, without any issues. If an activation error occurs, our support team can assist.
Does this version of Office work on a Mac?
No. This product is exclusively for Windows 10 and Windows 11. It is not compatible with macOS, iOS, or Android. For Mac users, a Microsoft 365 subscription or Office for Mac 2021 is required.
What payment methods do you accept?
Our checkout is powered by Stripe, allowing us to securely accept a wide range of payment methods including Visa, Mastercard, American Express, SEPA direct debit, iDEAL, BLIK, and Google Pay.
Do you provide a VAT invoice?
Yes. A full, EU-compliant VAT invoice is automatically generated and delivered with every purchase. This is suitable for business accounting and tax deduction purposes. For B2B customers with a valid EU VAT ID, the reverse charge mechanism can be applied.
What is your refund policy?
You are protected by the EU's statutory 14-day right of withdrawal for digital goods. If you have not yet downloaded or activated the software, you can request a full refund within 14 days of purchase. Please see our terms and conditions for full details.
