Hello, LouisWelcomme, it is available already, and you can check the pricing plans on this page, compare the features set of each of them and decide what you need.
There is an excellent set of license options: Dynamics 365 Sales Professional, Dynamics 365 Sales Enterprise, Dynamics 365 Sales Premium, and Microsoft Relationship Sales.
I recommend you find a solid Microsoft 365 backup solution too, like this one, as with ransomware, hacker attacks, and other sudden unpredictable situations it is vital that you prepare for recovery.
