About this licence
Microsoft Project 2021 Professional: Take Command of Complex Projects with a Standalone, Transferable Licence
Stop wrestling with spreadsheets and disconnected task lists. Microsoft Project 2021 Professional is the definitive, standalone project management application built for professionals who need to plan, track, and deliver complex initiatives on time and within budget. This is not a cloud subscription that holds your data hostage; it is a one-time purchase, a perpetual Retail licence that grants you permanent use of the software on your Windows PC. The key advantage is ownership and flexibility: your licence is not locked to a single machine. If you upgrade your hardware or reassign the software within your organisation, you can transfer it, making it a smart, long-term asset for your professional toolkit.
Designed for seasoned project managers, schedulers, resource planners, and independent consultants, this edition provides the full spectrum of Microsoft's powerful scheduling engine. From creating detailed Gantt charts and managing resource pools to performing critical path analysis, it equips you to model scenarios and make data-driven decisions. Delivered instantly as a genuine digital download from Lizensa, you gain immediate access to a tool that integrates seamlessly with your existing workflow, without the recurring fees of a subscription model.
Key Features and Benefits
Fully Featured Gantt Chart Timeline: Visualise your entire project schedule with pre-populated timelines. Drag and drop tasks, set dependencies, and instantly see the impact of changes, making complex timelines easy to communicate to stakeholders.
Comprehensive Resource Management: Assign resources to tasks, view their allocation, and identify overallocations before they cause burnout or delays. This ensures your team's workload is balanced and realistic from day one.
Automated Scheduling Engine: Leverage the power of critical path analysis. Let Project 2021 Professional calculate the most efficient task sequence and automatically adjust dates when you change a dependency, saving hours of manual recalculation.
Pre-built and Customisable Reports: Create professional status reports, burn-down charts, and financial overviews with a few clicks. Turn raw project data into compelling visuals for executive presentations without exporting to another tool.
Timesheet Submission for Progress Tracking: Allow team members to submit task updates and timesheets directly into the project plan. This provides a single source of truth for actual progress versus the baseline, improving accountability.
Seamless Microsoft 365 Integration: Connect your project plans with Microsoft Teams for collaboration, SharePoint for document management, and Excel for data analysis. This embeds project management into your existing Microsoft ecosystem.

What's Included with Your Purchase
When you purchase Microsoft Project 2021 Professional from Lizensa, you are acquiring a genuine, perpetual digital licence. Here is precisely what you will receive:
A Genuine Microsoft Retail Licence Key: This is a unique, verifiable activation key for a Retail licence. It is a one-time purchase with no expiry date, granting you permanent use of the software. This is not a time-limited subscription or a restricted OEM key.
Official Microsoft Download Link: You will receive a secure link to download the official installation media directly from Microsoft's servers. This guarantees you get a clean, unmodified version of the software.
Step-by-Step Activation Guide: A clear, easy-to-follow guide walks you through the installation and online activation process via Microsoft's official channel.
VAT Invoice: A proper, EU-compliant VAT invoice is provided immediately, essential for business accounting and tax purposes.
Multilingual Support: The product supports installation in English, German, French, Dutch, and Polish, allowing you to work in your preferred language.
Choosing the Right Edition
Understanding the Microsoft Project landscape is key to avoiding an expensive mistake. Here is how Project 2021 Professional compares to other editions:
Project 2021 Professional vs. Project 2021 Standard: The Standard edition is the core, entry-level desktop application. It includes Gantt charts, task management, and basic resource assignment. Professional adds the critical features serious project managers need: resource engagement, timesheets, and, most importantly, the ability to sync with Project Online and Project Server for enterprise-level collaboration. If you manage shared resource pools or need team members to report progress directly into the plan, Professional is the minimum requirement.
Project 2021 Professional vs. Project Plan 3/5 (Subscription): The cloud-based Project Plans are subscriptions that offer browser-based access and advanced co-authoring capabilities. Project 2021 Professional is a standalone, on-premises application. Choose the Professional desktop licence if you prefer a one-time cost, need to work offline, or do not require the collaborative features of the cloud platform. It is the ideal choice for a project manager who "owns" the schedule.
Who Needs Professional?: This edition is built for dedicated project managers, schedulers, and resource managers in medium-to-large businesses who need to model complex projects, manage enterprise resources, and integrate with a wider Microsoft ecosystem without committing to a monthly subscription.

FAQ — Frequently Asked Questions
Is Microsoft Project 2021 Professional a subscription or a one-time purchase?
This is a one-time, perpetual licence. Your purchase grants you the right to use the software indefinitely. There are no monthly or annual fees, unlike the cloud-based Project Plan subscriptions.
What is the difference between a Retail and an OEM licence?
A Retail licence, which this is, is transferable. If your computer fails or you upgrade to a new one, you can deactivate the software on the old device and reactivate it on the new one. An OEM licence is permanently tied to the first computer it is installed on and cannot be transferred.
How fast will I receive my licence key after purchase?
Our delivery process is fully automated. In the vast majority of cases, your licence key and download instructions are delivered to your email inbox and customer account in under 60 seconds after payment confirmation.
Is this a genuine and legal Microsoft licence?
Absolutely. Lizensa exclusively sources its product keys from authorised European distributors. You receive a legally compliant, verifiable licence that passes Microsoft's online activation, complete with a VAT invoice for your records.
What should I do if I have trouble activating the software?
First, ensure you are entering the key exactly as provided. If the online activation fails, the included guide explains how to use Microsoft's automated telephone activation system. If you still have trouble, our free EU-based technical support team is ready to assist you.
Can I reinstall this software or transfer it to a new computer?
Yes. The Retail licence type gives you this flexibility. If you reformat your PC or buy a new one, you can reinstall the software and reactivate it. You may need to use the telephone activation option if the online activation detects a significant hardware change.
Does this version of Project work on a Mac?
No. Microsoft Project 2021 Professional is designed exclusively for the Windows operating system (Windows 10 or Windows 11). It is not available for macOS.
What payment methods does Lizensa accept?
We offer a wide range of secure payment options through our Stripe-powered checkout. You can pay using credit/debit cards, SEPA bank transfer, iDEAL, BLIK, and Google Pay.
Do you provide a VAT invoice for business purchases?
Yes, a proper VAT invoice is automatically generated and provided with every purchase. For B2B customers with a valid EU VAT ID, the reverse charge mechanism can be applied, resulting in a net price invoice.
What is your refund policy?
Under EU consumer protection law, you have a 14-day right of withdrawal on digital goods. However, as the licence key is delivered instantly, we ask that you do not activate or reveal the key if you intend to exercise this right. Our support team will guide you through the process.
Can I use this licence for commercial projects?
Yes, this is a full commercial licence. It is perfectly suited for business, enterprise, and freelance project management work. There are no restrictions on its use for commercial purposes.
In which languages can I install Microsoft Project 2021 Professional?
