What actually differs
Dynamics 365 Customer Service is one app in Microsoft's business suite. Cases, contacts and accounts live in the same Dataverse records as Dynamics 365 Sales and the Power Platform, agents can work from Teams and Outlook, and Copilot drafts replies and summarises cases. It fits best when the rest of the company already runs on Microsoft and the service desk should share one customer record with sales.
Zendesk is a standalone service platform: ticketing, messaging, a help-centre knowledge base and AI agents, set up by a support team without a CRM project behind it. It reaches other systems through its Marketplace apps and APIs, and that is also how it usually meets Microsoft. Connecting Zendesk to Dynamics 365 CRM, or to Microsoft's ERP products (Dynamics NAV, now Business Central, and GP), runs through a Marketplace app, an integration platform or a custom API link rather than a shared database.
- Pick Microsoft Dynamics 365 Customer Service if your sales and operations already run on Dynamics 365 and you want service cases on the same customer record, inside Teams and Outlook.
- Pick Zendesk if you want a support desk your team can set up and run on its own, and you're happy to connect it to a CRM or ERP through integrations.
