Microsoft 365 Business plans are great for companies under 300 employees to start their journey with Office 365. The business premium package is by far the most popular offering, almost like a small business starter pack.
Microsoft 365 Business Premium is a complete, intelligent solution, including Office 365, Windows 10, and Enterprise Mobility + Security, that empowers SMBs to be creative and work together, securely.
Now, remember you can mix and match these plans. For example, ten people in your company can have the Business Premium plan, while five others get the Microsoft 365 Business plan.
