What Is Microsoft 365 for Small Business?
Microsoft 365 is a subscription-based productivity platform that bundles the familiar Office apps (Word, Excel, PowerPoint, Outlook) with cloud services like OneDrive, Teams, and SharePoint. Instead of buying software licenses outright, businesses pay a monthly or annual fee per user and get access to the latest versions of everything, including updates, security patches, and new features as they roll out.
For small businesses with up to 300 employees, Microsoft offers four plan tiers specifically designed to balance cost, features, and security. Whether you are a five-person startup or a growing company with a hundred team members, there is a plan that fits. This guide breaks down the pricing, features, and key advantages of Microsoft 365 for small business as of 2026.
Microsoft 365 Business Plans and Pricing (2026)
Microsoft offers four business plans, each priced per user per month. Paying annually rather than month-to-month saves you a bit on each plan. Here is what each tier includes and costs.
Microsoft 365 Business Basic: $6.00 per User per Month
This is the entry-level plan for small teams that mostly work in the cloud. It includes:
- Web and mobile versions of Word, Excel, PowerPoint, and Outlook (no desktop app installs).
- Microsoft Teams for chat, video calls, and meetings with up to 300 participants.
- 1 TB of OneDrive cloud storage per user.
- Exchange email hosting with a custom business domain (e.g., you@yourcompany.com).
- SharePoint and Microsoft Lists for team collaboration.
Best for: Remote teams, freelancers, and businesses that do most of their work in a web browser.
Microsoft 365 Business Standard: $12.50 per User per Month
This is the most popular plan for small businesses. It includes everything in Business Basic, plus:
- Full desktop app installs of Word, Excel, PowerPoint, Outlook, OneNote, and Access (PC only) on up to five devices per user.
- Microsoft Bookings for appointment scheduling.
- Microsoft Loop for collaborative workspaces.
- Clipchamp for basic video editing.
- Webinar hosting tools in Teams.
Best for: Businesses that need the full desktop Office experience and want collaboration tools beyond basic email and chat.
Microsoft 365 Business Premium: $22.00 per User per Month
This plan adds advanced security and device management on top of everything in Business Standard. Added features include:
- Microsoft Defender for Business for endpoint security and threat protection.

- Azure Information Protection for labeling and encrypting sensitive documents.
- Conditional access policies to control how and where employees sign in.

Best for: Businesses in regulated industries (healthcare, legal, finance) or any company handling sensitive customer data that needs strong security controls.
Microsoft 365 Apps for Business: $8.25 per User per Month
This plan is for teams that only need the Office desktop apps and cloud storage without email, Teams, or other collaboration services. It includes:
- Full desktop app installs of Word, Excel, PowerPoint, Outlook, OneNote, and Access (PC only).
- 1 TB of OneDrive cloud storage per user.
- No Exchange email, no Teams, no SharePoint.
Best for: Businesses that already use a different email provider and communication platform but want the latest Office desktop apps with cloud storage.
Key Features That Matter for Small Businesses
Beyond the core Office apps, Microsoft 365 includes several tools and capabilities that are especially useful for smaller teams.
Microsoft Teams: Your Communication Hub
Teams replaces the need for separate chat, video conferencing, and phone systems. You can run video meetings with up to 300 people, organize conversations into channels by topic or project, share files within chats, and even make and receive phone calls with an add-on calling plan. For many small businesses, Teams replaces Slack, Zoom, and a traditional phone system all at once.
Every user gets 1 TB of OneDrive storage, which is enough for most individuals. Files saved to OneDrive are accessible from any device and automatically sync across your desktop, laptop, phone, and tablet. SharePoint works as your team’s shared file library, intranet, and document management system. Together, they reduce the need for local file servers or third-party storage like Dropbox.
Exchange Online: Professional Email
Exchange gives your business professional email addresses at your own domain. Each user gets a 50 GB mailbox with shared calendars, contact management, and spam filtering built in. Outlook connects to Exchange and gives you a familiar interface for managing email, calendar events, and tasks.
Microsoft Copilot: AI-Powered Assistance
Starting in 2024 and expanded through 2025 and 2026, Microsoft has been rolling out Copilot, its AI assistant, across the 365 platform. Copilot can draft emails, summarize meetings, generate presentation slides, analyze spreadsheet data, and answer questions about your documents. The Copilot add-on is available as a separate per-user charge on top of your base plan, but basic Copilot features are increasingly being included in the standard subscription tiers as of mid-2026.
Microsoft Bookings: Appointment Scheduling
Bookings gives small businesses a self-service scheduling page where customers can book appointments based on your availability. It syncs with your Outlook calendar and sends automatic confirmation and reminder emails. This is particularly useful for service-based businesses like consultants, salons, repair shops, and medical practices.
Security and Compliance
Even the lower-tier plans include basic security features like multi-factor authentication (MFA), data loss prevention policies, and message encryption. The Business Premium plan adds endpoint protection, device management, and advanced threat detection, which can replace the need for separate security software.
How Microsoft 365 Compares to Google Workspace
Google Workspace (formerly G Suite) is the main alternative to Microsoft 365 for small businesses. Here is how the two platforms compare on the features that matter most to smaller teams.
| Feature | Microsoft 365 Business Standard | Google Workspace Business Standard |
|---|---|---|
| Price per user per month | $12.50 | $14.00 |
| Desktop apps | Full installs (Word, Excel, etc.) | Web-only (Docs, Sheets, etc.) |
| Cloud storage per user | 1 TB | 2 TB |
| Video conferencing | Teams (300 participants) | Google Meet (150 participants) |
| Email hosting | Exchange (50 GB mailbox) | Gmail (custom domain) |
| AI assistant | Copilot (add-on or included) | Gemini (add-on or included) |
| Offline editing | Full desktop apps work offline | Limited offline mode in Chrome |
Microsoft 365 tends to be the better choice if your team relies on desktop apps like Excel with advanced formulas and macros, or if you need Outlook’s powerful email management. Google Workspace is often preferred by teams that work primarily in web browsers and value the simplicity of Google’s interface. Both platforms offer competitive pricing, and many businesses choose based on which ecosystem their team already knows best.
Advantages of Microsoft 365 for Small Businesses
Predictable Monthly Costs
Instead of large upfront software purchases, Microsoft 365 spreads costs into manageable monthly payments. You can add or remove users as your team size changes, so you only pay for what you need. There are no surprise upgrade fees since the subscription always includes the latest software version.
Everything in One Place
By consolidating email, file storage, video calls, chat, scheduling, and Office apps under one subscription, small businesses can cut down on the number of separate tools they pay for. This often means canceling standalone subscriptions to services like Dropbox, Zoom, and Slack, which can more than offset the cost of Microsoft 365.
Work from Anywhere
All Microsoft 365 apps sync across devices. Start a document on your office desktop, edit it on your laptop at a coffee shop, and review it on your phone during a commute. OneDrive keeps everything in sync automatically, and the mobile apps are full-featured enough for real work on the go.
Built-in Security
Even the entry-level plans include multi-factor authentication, encrypted email, and admin controls for managing user access. The Business Premium tier adds enterprise-grade security features that would cost hundreds of dollars per user through third-party security vendors. For small businesses that handle customer data, this built-in protection is a major advantage.
Scales with Your Business
Microsoft 365 Business plans support up to 300 users. When you outgrow that limit, upgrading to an Enterprise plan is straightforward and keeps all your data, settings, and configurations intact. You do not have to migrate to a new platform as your company grows.
Potential Downsides to Consider
No platform is perfect for every business. Here are a few things to keep in mind before committing to Microsoft 365.
- Subscription costs add up. At $12.50 per user per month for Business Standard, a 20-person team pays $3,000 per year. Make sure you are using enough of the included tools to justify the cost versus free alternatives.
- Learning curve. If your team is used to Google Workspace or other tools, switching to the Microsoft ecosystem takes some adjustment. Budget time for training, especially with Teams and SharePoint.
- Feature overlap can be confusing. Microsoft 365 includes so many apps and services that it can be hard to know which tool to use for what. Teams, SharePoint, OneDrive, and Loop all handle file sharing in slightly different ways, which can create confusion if you do not set clear guidelines for your team.
- Admin complexity. Managing users, permissions, and security settings through the Microsoft 365 Admin Center takes some technical knowledge. Very small businesses without IT staff may find this overwhelming at first.
How to Get Started
Microsoft offers a free one-month trial of each business plan. This gives you enough time to set up email, install the desktop apps, try Teams, and see if the platform fits your workflow before committing.
- Go to the Microsoft 365 for Business page at microsoft.com.
- Choose the plan that matches your needs (Business Standard is the most popular starting point).
- Sign up with your business email or create a new Microsoft account.
- Set up your custom domain for professional email addresses.
- Invite your team members and assign licenses.
- Download the desktop apps and start working.
You can switch between plans at any time, so starting with a lower tier and upgrading later is a reasonable approach if you are unsure which features your team needs.
Wrapping Up
Microsoft 365 remains one of the strongest productivity platforms for small businesses in 2026. The combination of familiar Office apps, cloud storage, team communication, and built-in security covers the needs of most small teams at a predictable monthly cost. The Business Standard plan at $12.50 per user per month hits the sweet spot for most companies, but all four tiers offer solid value depending on your priorities. Take advantage of the free trial to test the platform with your team before making a decision.
