Microsoft Dynamics 365 and Odoo are two of the most capable business management platforms available to SMEs and mid-market companies. They cover much of the same functional ground — sales, operations, finance, HR — but are built on fundamentally different philosophies: one is a tightly integrated Microsoft cloud extension; the other is an open-source, modular ERP from a Belgian company. We implement Odoo and understand the Microsoft ecosystem well enough to give you a straight comparison.
What each platform covers
Dynamics 365 is a family of applications sold modularly: Sales (CRM), Marketing, Business Central (accounting and operations for SMEs), Finance & Operations (enterprise finance and supply chain), Customer Service, Field Service, HR and Commerce. Most SMEs use Dynamics 365 Business Central — the successor to Navision — which covers accounting, purchasing, inventory and basic project tracking.
Odoo is a single, modular open-source platform covering CRM, sales, accounting, inventory, manufacturing, project management, eCommerce, HR, payroll, helpdesk and more. Modules are activated individually on a shared database, so adding functionality doesn't require a separate integration project — it's already built in.
Pricing: a significant difference
Dynamics 365 Business Central Essentials lists at around €70/user/month; Premium at around €100/user/month. These are baseline licence costs only — implementation, configuration and customisation are purchased separately through a Microsoft partner and represent a substantial additional cost for most deployments.
Odoo Community is free and open source. Odoo Enterprise starts at around €28/user/month for the platform, with app modules priced per user on top. A typical Odoo Enterprise deployment covering CRM, sales, accounting and inventory typically costs significantly less per user than a comparable Dynamics 365 Business Central deployment, and implementation time tends to be shorter.
Where Dynamics 365 is the better answer
- Organisations already deeply invested in the Microsoft stack — Teams, SharePoint, Azure AD, Power Platform — where native Dynamics integration is a genuine workflow advantage
- Companies with complex sales team structures using Dynamics 365 Sales as a CRM, where Outlook and Teams integration is operationally important
- Businesses needing Finance & Operations at enterprise scale, with global multi-entity complexity requiring Microsoft's depth
- Regulated sectors already running on Azure with existing Microsoft compliance certifications that apply to their sector
Where Odoo is the better answer
- SMEs and mid-market businesses that want a complete ERP without enterprise pricing
- Companies that want one platform — CRM, accounting, inventory, eCommerce, HR — without stitching separate products together
- Businesses that value open source: full code access, no vendor lock-in, ability to self-host if required
- European businesses that prefer a Belgian-headquartered vendor and EU data residency as the default
- Fast-growing companies that need to activate new modules without starting a new implementation project
Data and sovereignty
Dynamics 365 runs on Microsoft Azure. The same EU Data Boundary and CLOUD Act considerations that apply to Microsoft 365 apply here. For complete control of data residency, self-hosted Odoo Community or Enterprise on a European VPS is the strongest option — your data stays exactly where you put it, under exactly the law that governs that server. Odoo is a Belgian company; EU data residency is the default for Odoo.sh deployments.
Solvetus implements and supports Odoo
We are an Odoo implementation partner. We scope, configure, migrate data and train teams on Odoo deployments for SMEs and mid-market businesses. Our implementations typically cover CRM, accounting, inventory, purchasing and HR. We also provide ongoing support and module expansions after go-live. If you are evaluating Odoo against Dynamics 365, we can give you a concrete picture of what a deployment would look like for your specific situation.
Frequently asked questions
- Can we migrate from Dynamics 365 to Odoo?
- Yes. Migrations from Dynamics 365 Business Central (and the older NAV/Navision systems) are possible and we handle them. Complexity depends on historical data volume, custom fields and active integrations. Most SME migrations from Business Central are achievable within a structured project.
- How long does an Odoo implementation typically take?
- For a typical SME scope — CRM, accounting, inventory and purchasing — an Odoo implementation usually takes 6 to 14 weeks from kick-off to go-live. Dynamics 365 Business Central implementations at comparable scope typically take longer.
- Does Odoo integrate with Microsoft 365?
- Yes. Odoo has native integration with Microsoft 365 for email (Outlook), calendar (Exchange/Outlook) and document sharing (OneDrive/SharePoint). Moving to Odoo for ERP doesn't require leaving Microsoft 365 for email and collaboration.
- What's the difference between Odoo Community and Enterprise?
- Community is free and open source but excludes key modules: full accounting, manufacturing (MRP), payroll, sign, helpdesk and the mobile app. Enterprise includes all modules and Odoo's support contract. Most production deployments use Enterprise.
- Is Odoo GDPR compliant?
- Yes. Odoo is a Belgian company and the platform is built to support GDPR compliance. Deployed on EU infrastructure (standard for Odoo.sh and most European partner deployments), personal data stays within EU jurisdiction.
