What are the hidden costs in Dynamics 365?

Four typical hidden costs. (1) Premium Connectors: SQL Server, custom REST API, on-premises gateway need separate Power Automate Premium licence (15 USD/user/month). (2) Dataverse API request limit: 6,000 req/day default, intensive integrations need add-on capacity 20-100 USD/month. (3) ALM specialist: managed/unmanaged solution lifecycle (DEV/UAT/PROD environments), typical day rate 800-1,500 EUR. (4) Power Apps environment per-app licence 5 USD/user/month if a custom model-driven app is built next to Sales. A realistic 50-seat 5-year all-in TCO often lands at 600-900k USD.

When is Dynamics 365 the right choice over a custom CRM?

When the company is a Microsoft 365 + Azure shop with major Power Platform investment already: existing Power Apps, Power BI dashboards, Office 365 E3/E5 licence pack. Then Dynamics 365 plugs straight into Azure AD, Outlook, Teams, and Power Platform developers are reusable. Other case: ALM-disciplined company with a Power Platform CoE (Center of Excellence) and managed solution governance in-house. For Hungarian 50-150 person sales teams with NAV integration and Hungarian language nuance: custom CRM at 18-45 million HUF usually wins.

How do I migrate from Dynamics 365 to a custom CRM?

Tools: Microsoft Data Migration Framework (DMF), Dataverse API for delta sync, KingswaySoft SSIS connector for bulk export. 50-100 seat migration timeline 6-10 weeks parallel run: weeks 1-2 schema mapping (Account, Contact, Opportunity, Custom Tables), weeks 3-5 history and attachment migration, weeks 6-8 UAT, weeks 9-10 cutover. Power Automate flows are rewritten in Python + Temporal (or n8n). Realistic migration project fee 4-9 million HUF on top of the 18-45 million HUF custom CRM.

What does ALM (DEV/UAT/PROD) look like in a custom CRM?

Custom CRM uses a git-versioned codebase (GitHub or GitLab), trunk-based development, branch protection, mandatory code review. Three environments: DEV (preview deploy on every PR), UAT (staging, customer-testable), PROD (live). CI/CD on GitHub Actions, automated tests (unit, integration, E2E Playwright). Every release ships migration scripts (Drizzle or Prisma migrations) and rollback. Compared to the Dynamics managed/unmanaged solution model, this is more transparent and automated — without a dedicated ALM specialist. The process is documented and audit-ready (NIS2, ISO 27001).

What is the Hungarian-context difference: Dynamics vs custom CRM?

Three Hungarian-market points. (1) NAV Online Számla 3.0: in Dynamics, third-party AppSource partner module, often 4-8 weeks behind NAV schema updates. In custom CRM, native, included in maintenance. (2) Hungarian-language UX: Dynamics translations have machine-translation feel; custom CRM ships native Hungarian copy. (3) NAV reporting integration (online invoicing, purchase-side, EKAER): in custom CRM at the depth required — in Dynamics limited to the partner module's depth. NAV Online Számla 3.0 schema follow is included in the 0.5-1.5 million HUF/year custom CRM maintenance.

Feature parity — Hungarian-market context

Items below are about Dynamics 365 Sales Enterprise out-of-the-box. Each is achievable in Dynamics, via AppSource module, Power Platform development or Premium Connector licence.

Custom CRM — native

· NAV Online Számla 3.0 XML reporting
· EU-only data residency (Hetzner / Cloudflare EU)
· Native Hungarian UX, Hungarian docs
· HTTP / SQL / on-prem API native, no Premium connector
· No Dataverse API request limit
· Git-versioned codebase, GitHub Actions CI/CD
· Multi-LLM AI lead scoring (Claude / GPT-4 / local)
· Source-code escrow, on-prem deploy option

When Dynamics 365 IS the right answer

Dynamics 365 is the right call for roughly 25-35% of Hungarian buyers. Concrete conditions below.

Microsoft 365 + Azure shop: existing Power Platform investment (Power Apps, Power BI dashboards), Office 365 E3/E5 licence pack, Azure AD identity. Dynamics 365 plugs in directly.
ALM-disciplined organisation: in-house Power Platform Center of Excellence (CoE), managed solution governance, ALM specialists on staff.
Power Platform citizen developer culture: business users build apps and flows themselves. Power Platform low-code / no-code wins are realised.
Complex multi-tenant, multi-region: Azure AD + Dynamics 365 multi-region deployment is plug-and-play, expensive to replicate in custom CRM.

For a 50-150 person Hungarian sales team with NAV integration and Hungarian language nuance, custom CRM almost always wins on 5-year TCO.

Dynamics 365 migration — 5-step plan
