Microsoft 365 licensing comes in different versions - with one for smaller businesses and three for larger corporations. How do you determine which plan is going to add the most value to your organization?


All businesses share common needs: increasing productivity, working more efficiently, and securing their data. Before smaller organizations were forced to pay for Enterprise subscriptions that had features they would never use, or they would just live without. That’s no longer the case with Microsoft 365 Business —organizations now have their own value bundle.

Now Microsoft is offering Microsoft 365 Business, combining the productivity tools and features of Office 365, with the security of Windows 10. This cost-effective subscription is built specifically for small and midsize businesses to empower their team to be more productive through collaboration while keeping a peace of mind that their data is secured.

When looking at these subscriptions, it’s important to understand the differences between M365 Business and M365 Enterprise E3 because it is not always obvious which option is best for your business. This blog will dive into the comparison of each option to help guide your decision. To start off, why should companies choose Microsoft 365 in general?

Why Microsoft 365?

M365 Business – The Basics

What is this new offering and how can you decide if it’s right for your business? This solution was designed with small, midsized or growing businesses in mind. It’s powered by the productivity and collaboration tools of Office365, including Word, Excel, PowerPoint, Outlook, Teams, SharePoint, and more – while staying secure and controlled with Windows 10. It offers the centralized management capabilities of users, devices, and apps that previously were only available to larger enterprises. These management capabilities are on one easy-to-use console, which is perfect for businesses with growing or limited IT staff. The plan also comes with Office 365 Advanced Threat Protection (ATP), which is used to provide advanced protection against malware and hijacked URL links. 

Microsoft 365 Licensing: Making the Decision
