The Dynamics 365 commercial complexity
Microsoft Dynamics 365 is genuinely capable enterprise software. It is also the most licensing-complex CRM in this comparison. A 'Dynamics 365 implementation' requires selecting among: Dynamics 365 Sales (Professional, Enterprise, and Premium tiers), Dynamics 365 Customer Service (similar tier ladder), Dynamics 365 Marketing (licensed separately), Dynamics 365 Field Service, Dynamics 365 Customer Insights (data and journeys licensed separately), plus Dataverse capacity, plus Power Platform licenses for any custom workflows, plus Microsoft 365 licenses as a practical prerequisite (most customers don't run Dynamics without M365). KamoCRM Business is $119/seat/month for a platform that delivers the core of Sales + Customer Service + Marketing + Field Service scopes together.
