Going live tomorrow (21st April 2020) Microsoft are renaming some of the Office 365 and Microsoft 365 products. I guess this is what happens when the marketing department have too much time on their hands.
They are bringing all the Business Office 365 range into a Microsoft 365 naming convention.
|Office 365 Business Essentials||is now||Microsoft 365 Business Basic|
|Office 365 Business Premium||is now||Microsoft 365 Business Standard|
|Microsoft 365 Business||is now||Microsoft 365 Business Premium|
|Office 365 Business||is now||Microsoft 365 Apps for business|
|Office 365 ProPlus||is now||Microsoft 365 Apps for enterprise|
