Microsoft offers various pricing bundles for the Dynamics 365 apps, which can be viewed here. The major distinction made in these bundles is between Enterprise edition and Business edition. Simply put, Enterprise edition is Microsoft’s software bundle designed for bigger companies and the operations portion is built from Dynamics AX, while Business edition is designed for smaller companies and the financial capabilities built from Dynamics NAV. The key difference between these two editions is that the Enterprise edition includes the Dynamics 365 for Operations app, and the Business Edition includes the Dynamics 365 for Financials app. The Operations and Financials applications are mutually exclusive financial suites, which means businesses would subscribe to one or the other, but not to both.
