Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi IanDaut
Greetings
Thank you for posting in Microsoft Community
I would suggest using Dynamics 365, because you get CRM software that works as a customizable solution designed to suit business requirements. You can either choose a stand alone application to meet the needs of a specific line of business, or use multiple CRM tools that work well together. It also uses CRM apps and integrates them with Azure and Microsoft 365.
