Microsoft 365 Business Premium (12-Month, Monthly Billing) — Enterprise-Grade Security for the Agile Business
For small and medium-sized businesses navigating hybrid work, the challenge isn't just productivity—it's securing company data across devices, locations, and applications without a dedicated security operations centre. Microsoft 365 Business Premium solves this by bundling the full Office suite, cloud collaboration tools, and a comprehensive enterprise-grade security stack into a single, manageable subscription. This 12-month plan, billed monthly, gives you predictable cash flow while equipping your team with Microsoft Defender for Business, Intune device management, and Azure Information Protection. Lizensa provides an instantly delivered, genuine EU-licensed digital key, so you can deploy advanced threat protection and compliance tools to up to 300 users without the upfront annual cost.
Key features and benefits
- Premium Office desktop apps with cloud integration — Get the latest versions of Word, Excel, PowerPoint, Outlook, OneNote, Publisher (PC), and Access (PC), always up to date. Install on up to 5 PCs or Macs, 5 tablets, and 5 phones per user, ensuring your team can work seamlessly from any device.
- Microsoft Defender for Business — Enterprise-grade endpoint protection that shields your devices from ransomware, phishing, and malware. Automated investigation and remediation reduce the burden on IT staff, helping prevent breaches before they disrupt operations.
- Microsoft Intune for device management — Enforce security policies, manage app deployment, and remotely wipe company data from lost or stolen devices. Conditional Access ensures only compliant, trusted devices connect to your business resources, a critical layer for zero-trust security.
- Exchange Online with 50 GB mailbox — Business-class email with a 50 GB inbox, custom domain support, and advanced anti-spam and anti-malware filtering. Includes email encryption and legal hold capabilities, essential for law firms, consultants, and financial services.
- Microsoft Teams with calling and webinars — Host HD video meetings for up to 300 attendees, record sessions with automatic transcripts, and enable phone calling with a Teams Phone add-on. Webinar features make it easy to engage clients and prospects professionally.
- SharePoint and OneDrive for Business — Each user receives 1 TB of personal cloud storage via OneDrive, plus shared team sites through SharePoint. Real-time co-authoring, version history, and granular sharing controls keep collaboration secure and efficient.
- Azure Information Protection (Premium) — Classify, label, and protect sensitive documents automatically. Data Loss Prevention (DLP) policies prevent accidental sharing of financial data, personal identifiable information (PII), or intellectual property across email and cloud storage.
- Microsoft Bookings and Invoicing — Simplify appointment scheduling and payment collection. Bookings integrates with your Outlook calendar, letting clients self-schedule appointments, while Invoicing (available in select markets) helps generate professional invoices.
- Windows 11/10 Business upgrade rights — If you have devices running Windows 10/11 Pro, this license grants step-up rights to Windows 10/11 Business, unlocking additional device management and security features through Intune.
- Monthly billing flexibility — A 12-month commitment with monthly payments preserves working capital. No large upfront annual payment; the subscription auto-renews monthly, and you can cancel before the renewal date to avoid the next term.
What's included with your purchase
When you order from Lizensa, you receive a genuine, EU-sourced Microsoft 365 Business Premium subscription license. This is a 12-month term, billed monthly, and is not a lifetime or perpetual license. Your purchase includes:
- Digital license key — Delivered instantly to your email and Lizensa customer account dashboard. This key is redeemed via the Microsoft 365 admin centre (admin.microsoft.com) to activate the subscription on your tenant.
- Activation guide — Step-by-step instructions for tenant setup (if you don't have one) and license assignment. We cover both new and existing Microsoft 365 tenants.
- VAT invoice — A compliant EU VAT invoice is provided immediately. For B2B customers with a valid VAT ID, reverse charge is applied where applicable.
- License management — You manage user assignment through the Microsoft 365 admin centre. Licenses can be reassigned as your team changes, up to the purchased seat count.
- Compatibility — Works across Windows (10, 11), macOS (the three most recent versions), iOS, and Android. Full desktop apps are available for Windows and macOS; mobile apps are available for all platforms.
Office versions compared — which one should you buy?
Choosing between a one-time Office purchase and a Microsoft 365 subscription depends on your security needs, update cadence, and collaboration requirements.
- One-time purchase (Office 2021/2019) — A perpetual license for one PC or Mac. You pay once and own it, but you receive only security updates—no new features. It includes classic apps (Word, Excel, PowerPoint) but lacks cloud services, advanced security, and device management. Best for a single user with basic needs and no requirement for team collaboration or compliance tools.
- Microsoft 365 Business Basic — A cloud-only subscription with web and mobile versions of Office apps, plus Teams, Exchange, SharePoint, and OneDrive. No desktop apps. Suitable for frontline workers or users who primarily work in a browser.
- Microsoft 365 Business Standard — Adds full desktop Office apps to the Business Basic plan, plus desktop versions of Publisher and Access. Ideal for businesses that need traditional desktop software and cloud collaboration but don't require advanced security or device management.
- Microsoft 365 Business Premium (this product) — The complete package. Includes everything in Business Standard plus Microsoft Defender for Business, Intune, Azure Information Protection, and Conditional Access. This is the right choice for businesses that handle sensitive client data, operate in regulated industries, or support a hybrid workforce where devices leave the office network.
If your business stores customer financial data, legal documents, or medical records, or if you simply want to prevent a ransomware incident from destroying your operations, Business Premium is the edition that delivers the necessary security controls without requiring a dedicated IT security team.

FAQ — frequently asked questions
Is Microsoft 365 Business Premium a subscription or a one-time purchase?
It is a subscription. This specific plan has a 12-month commitment, billed monthly. Your subscription auto-renews each month for the full term. You can cancel before the renewal date to stop the next billing cycle.
What's the difference between this monthly plan and an annual prepaid plan?
The monthly plan spreads the cost over 12 months, improving cash flow, while an annual prepaid plan requires the full payment upfront. Both provide the same software and services for a 12-month period. The monthly plan typically has a slightly higher total cost over the year compared to the annual commitment paid upfront.
How fast do I get my license key after purchase?
Your license key is delivered digitally within seconds. You'll receive it by email and it will be available immediately in your Lizensa customer account dashboard. There is no physical shipment.
Is this a genuine, legal Microsoft license?
Yes. Lizensa supplies only 100% genuine licenses sourced from authorised European distributors. You receive a legitimate product key that activates directly with Microsoft and is valid for use in all EU countries.
What if I have trouble activating the license?
Contact Lizensa's EU-based support team. We provide free assistance with activation errors, tenant setup, and license assignment. If a key is verified as defective, we will replace it promptly.
Can I reinstall the software or transfer the license to a new user?
Yes. Each licensed user can install Office on up to 5 PCs or Macs, 5 tablets, and 5 phones. You can deactivate installations from old devices and reinstall on new ones. To transfer a license to a different person, simply unassign the license from the departing user in the Microsoft 365 admin centre and assign it to the new user.
Does this license work on Mac computers?
Yes. Microsoft 365 Business Premium includes full desktop versions of Word, Excel, PowerPoint, Outlook, and OneNote for macOS, along with Teams and OneDrive. Publisher and Access are available on Windows only.
What payment methods does Lizensa accept?
We accept Visa, Mastercard, American Express, Google Pay, Apple Pay, SEPA bank transfer, iDEAL, and BLIK. All payments are processed securely through Stripe.
Do you provide a VAT invoice?
Yes. A compliant EU VAT invoice is generated automatically with every purchase and delivered with your license key. For B2B customers, reverse charge is applied when a valid EU VAT ID is provided at checkout.
What is your refund policy?
Under EU consumer law, you have a 14-day right of withdrawal from the date of purchase. If the license key has not been redeemed or activated, we will issue a full refund. If you encounter a technical issue, our support team will first attempt to resolve it before processing a return.
Do I need an IT department to use Microsoft 365 Business Premium?
No. While the security and device management features are powerful, they are designed to be configured by a business owner or office manager without deep IT expertise. The Microsoft 365 admin centre provides guided setup, and Lizensa's support team can assist with initial configuration questions.
How many users can I license with this plan?
Microsoft 365 Business Premium supports up to 300 users per tenant. You can purchase as many individual licenses as you need, up to that limit, and manage them all from a single admin centre.
