There are several Office 365 for business plans that you or your organization can choose from when you sign up for one of Microsoft's cloud services. After your organization signs up for Office 365, the admin can assign different Office 365 licenses to each user account. The different licenses include different services, such as SharePoint Online and Skype for Business Online. See the different Office 365 for business plans.
Note: This topic is for Office 365 for business. If you have an Office for home product and you're looking for where to install Office, see Install or reinstall Office on a PC or Mac.
