Yes. You can transition your account to a different plan as the needs of your business change.

Our Microsoft 365 Business base per user plans are designed for organizations with up to 300 users. Organizations with more than 300 users should consider subscribing to Microsoft 365 Enterprise plans. We reserve the right to enforce a tenant limit of 300 provisioned licenses across the Business family of plans, in which case we will provide advance notice and further guidance. In the meantime, we are treating customers that have provisioned up to 300 licenses of each individual Business plan (Business Basic, Business Standard, Business Premium) as compliant with this 300-seat limit, even if they have provisioned more than 300 total licenses across the Business family of plans.

Many customers purchase a business SKU and then, depending on their needs, they may choose to buy any number of add-on Microsoft 365 services to round out their implementation. Customers with Microsoft 365 E3 subscriptions, or a version of the suite that do not include Microsoft Teams, are eligible to purchase Microsoft 365 E5 compliance and Microsoft 365 E5 security as add-ons to their Microsoft 365 E3 subscriptions. Depending on the subscription level, customers can also combine their Microsoft 365 Enterprise subscriptions with plans and add-ons from Azure, Dynamics 365, and Enterprise Mobility + Security.
