Key Takeaway: Microsoft 365 Business Premium includes EDR, device management, and conditional access that cyber insurance carriers now require as a condition of coverage. The client who is paying separately for a third-party EDR, MDM platform, and conditional access solution is likely paying more than the Business Premium premium while getting less integrated security.
Microsoft 365 licensing is one of the most common sources of client confusion and MSP advisory opportunity. Most business owners know they need Microsoft 365 but do not understand the difference between the tiers, which features matter for their business, and whether they are paying for capabilities they are not using. The MSP that can navigate this conversation clearly is delivering genuine vCIO value.
This guide covers the Microsoft 365 business tiers, what each includes, and how to help clients choose the right tier for their specific situation.
The Microsoft 365 Business Tiers
Microsoft offers four primary tiers for small and mid-sized businesses. The pricing below reflects current Microsoft list pricing; actual pricing through CSP partners may vary.
Microsoft 365 Business Basic ($6/user/month). The entry-level tier includes web and mobile versions of Office apps (no desktop apps), Exchange email with 50 GB mailbox, Teams, SharePoint, and OneDrive with 1 TB storage. It does not include desktop versions of Word, Excel, PowerPoint, or Outlook. It is appropriate for businesses where employees primarily work in a browser and do not need the full desktop Office experience.
Microsoft 365 Business Standard ($12.50/user/month). Adds desktop versions of all Office apps (Word, Excel, PowerPoint, Outlook, Access, Publisher) to everything in Business Basic. Also includes Microsoft Bookings, MileIQ, and additional Teams features. This is the most common tier for businesses that need the full Office experience and basic collaboration tools.
Microsoft 365 Business Premium ($22/user/month). Adds enterprise-grade security to everything in Business Standard: Microsoft Defender for Business (EDR), Intune for device management, Azure AD Premium P1 for conditional access, Microsoft Purview for information protection, and Azure Information Protection. This is the tier that cyber insurance carriers are increasingly requiring as a condition of coverage, and it is the tier that MSPs should be recommending for most business clients.
Microsoft 365 Apps for Business ($8.25/user/month). Desktop Office apps plus OneDrive, but without Exchange email. Appropriate for businesses that use a different email provider and only need the Office applications.
Why Business Premium Is the Right Default for Most Clients
The security features included in Microsoft 365 Business Premium are not optional extras for businesses that want to be secure. They are the baseline security controls that cyber insurance carriers now require as a condition of coverage.
Microsoft Defender for Business, included in Business Premium, provides endpoint detection and response (EDR) that meets the carrier requirement for behavioral endpoint security. Intune provides the device management and compliance enforcement that carriers require for conditional access. Azure AD Premium P1 provides the conditional access policies that enforce MFA based on risk signals, which is the MFA standard that carriers require.
The client who is on Business Standard and paying separately for a third-party EDR solution, a separate MDM platform, and a separate conditional access tool is likely paying more than the $9.50 per user per month premium for Business Premium, while getting less integrated security. The Business Premium conversation is often a cost optimization conversation as much as a security conversation.
The Copilot Add-On
Microsoft 365 Copilot is available as an add-on to Business Basic, Business Standard, and Business Premium at $30 per user per month. It requires a base Microsoft 365 subscription and provides AI assistance integrated into Word, Excel, PowerPoint, Outlook, and Teams.
The Copilot add-on is not appropriate for every user or every business. The users who benefit most are knowledge workers who spend significant time on document creation, email management, and meeting preparation. The users who benefit least are those whose work is primarily operational or field-based.
Before recommending Copilot, the MSP should conduct a data governance review. Copilot has access to everything the user has access to in Microsoft 365. Organizations with poor data governance, broadly shared documents, and inconsistent permissions will surface sensitive information through Copilot that was technically accessible but practically invisible before. The governance work before deployment is not optional.
Common Licensing Mistakes
Mixing tiers without a plan. The organization that has some users on Business Basic and others on Business Premium has a security gap: the Business Basic users do not have EDR or device management, which means they are the weakest link in the security posture. If the organization needs Business Premium security, all users should be on Business Premium.
Paying for unused licenses. The organization that has 25 licenses but only 20 active users is paying for 5 unused licenses. Regular license audits, at least quarterly, identify unused licenses and reduce unnecessary cost.
Not using included features. The organization on Business Premium that is not using Defender for Business, Intune, or conditional access is paying for security features they are not receiving. The MSP that deploys and configures these features is delivering the value the client is already paying for.
Frequently Asked Questions
What is the difference between Microsoft 365 and Office 365?
Office 365 was the original name for Microsoft’s cloud productivity suite. Microsoft 365 is the current name and includes everything in Office 365 plus additional security and device management features. The Business Premium tier of Microsoft 365 includes security features that were not part of the original Office 365 offering.
Do I need Microsoft 365 Business Premium for every user?
For most businesses, yes. The security features in Business Premium are most valuable when they are applied consistently across all users. A single user without EDR or device management is a potential entry point for an attacker. The cost of a security incident on an unprotected device typically exceeds the cost of upgrading that user to Business Premium for several years.
How do I help a client who is resistant to the Business Premium price?
Show them what they are already paying for separately. The client who is paying for a third-party EDR, a separate MDM platform, and a separate conditional access solution is likely paying more than the Business Premium premium. Calculate the total cost of their current security stack and compare it to Business Premium. The conversation often becomes a cost optimization conversation rather than a cost increase conversation.
