Dynamics 365 and Salesforce are the two serious enterprise CRM platforms, and on core functionality they are closely matched. Both handle pipeline, forecasting, case management and marketing automation to a standard that will not limit a typical mid-market organisation. Choosing between them on a feature checklist rarely produces a useful answer.
The real differences are structural. Dynamics 365 is part of the wider Microsoft stack, so it shares identity, security, reporting and low-code tooling with Microsoft 365 and can sit alongside Business Central for finance. Salesforce is a standalone platform with the larger third-party marketplace and a deeper pool of independent specialists, and it prices each product separately.
That leads to a fairly reliable rule of thumb. If your organisation already runs on Microsoft 365, Dynamics 365 will usually cost less, deploy faster and be adopted more readily, because the interface and the login are already familiar. If you need a specialist vertical product that only exists on AppExchange, or you run a very large dedicated sales organisation, Salesforce earns its premium.
