Choosing the right Enterprise Resource Planning (ERP) system is a strategic decision that affects cost, control, and scalability. Microsoft Dynamics 365 Business Central is Microsoft’s current mid-market ERP, while some organisations still run the legacy platform, Microsoft Dynamics NAV (formerly Navision). Both systems support core finance and operational processes—and can be extended to improve customer-facing workflows—but they differ significantly in architecture, update model, and extensibility. The differences matter when deciding whether to upgrade to dynamics 365 business central or remain on NAV—especially around cloud readiness, supportability, and long-term cost. This erp system comparison compares NAV and Business Central across integration, deployment, customisation, scalability, cost, and upgrade risk—so you can choose the right path for your organisation; for a deeper dive, see a detailed comparison here.
A Short Introduction to Dynamics 365 NAV
Microsoft Dynamics NAV (formerly Navision) has long been a popular ERP for small and mid-sized organisations. It includes core capabilities across finance, supply chain, manufacturing, reporting, and—through extensions or integrations—CRM and eCommerce scenarios. NAV is known for flexibility—especially in heavily customised environments—although those customisations can increase upgrade effort over time. For authoritative guidance on NAV, visit the official Microsoft documentation page here.
A Brief Introduction to Dynamics 365 Business Central
Dynamics 365 Business Central (released in 2018) evolved from NAV and is designed to work natively with Microsoft 365 and Power BI enabling richer integrations and a modern extension-based customisation model. Dynamics 365 Business Central is designed as an all-in-one ERP for small and mid-sized organisations; companies with more complex enterprise requirements may evaluate Dynamics 365 Finance and Supply Chain Management (F&SCM). It supports finance and operations out of the box and connects easily to CRM, Power Platform, and analytics tools to unify end-to-end processes.
Key Differences of Microsoft Dynamics 365 Business Central vs Dynamics NAV
Below are the key differences that most influence an upgrade decision. NAV and Business Central share common roots, but the differences below are often the reasons organisations choose to move from NAV to Business Central.
Platform Integration and Accessibility
Business Central integrates tightly with Microsoft 365 and Power Platform, including Power Automate, helping teams standardise workflows across the Microsoft ecosystem. For teams building lightweight apps around approvals or data capture, Power Apps can reduce manual handoffs between systems. Business Central is cloud-first (Business Central Online) and is also available as an on-premises deployment for organisations that require it.
Dynamics nav was built primarily for on-premises deployment; later versions can be hosted in the cloud, but the operating model and update cadence differ significantly from Business Central Online. However, NAV’s native cloud-era integrations are less mature than Business Central’s—which can be a disadvantage for organisations standardising on Microsoft 365 and Power Platform.
User Interface and Experience
Business Central has a modern interface aligned with other Dynamics 365 applications, which reduces onboarding time for teams already using Microsoft tools. The UI is built for faster navigation, role-based work, and collaboration in Microsoft 365.
In Dynamics nav, the classic interface can feel dated and may require more training for users who are used to modern web-based business apps. That said, long-time NAV users often value its familiarity—and some organisations rely on deep customisation to support unique processes.
Customization and Scalability
Business Central supports customisation, but it encourages a different approach from NAV. It prioritises extensions instead of modifying the core application, which typically makes upgrades simpler and reduces regression risk. This helps preserve system integrity and lowers long-term maintenance overhead. It also improves scalability and makes future changes easier to govern. Business Central—especially in the cloud—benefits from Microsoft’s managed infrastructure, enabling organisations to scale users and capabilities with less operational overhead.
Dynamics nav can be heavily customised, which can be valuable when processes are genuinely unique and cannot be supported by configuration alone. However, extensive code-level modifications often increase upgrade effort and long-term technical debt. While NAV can scale, its architecture may require more infrastructure and bespoke optimisation as transaction volumes and integrations grow.
Cost Implications and Target Audience
Dynamics 365 business central is aimed at small to mid-sized organisations that want a modern ERP with a clearer upgrade path and lower operational overhead. Business Central can be more cost-effective because it offers subscription licensing and—when deployed in the cloud—reduces upfront infrastructure investment; with subscription licensing, business central pricing is typically easier to forecast than large upfront infrastructure spend.
NAV can be a fit for organisations that depend on legacy customisations and have stable requirements they are not ready to re-platform yet. However, its implementation can involve higher upfront costs—especially on-premises—due to infrastructure requirements and the effort needed to build and maintain customisations, and nav cost can rise further when bespoke changes have to be carried forward release by release.
Feature Comparison Table
The table below summarises the most decision-relevant differences between NAV and Business Central.
| Features | Navision | Business Central |
|---|---|---|
| Deployment Options | Primarily on-premises with some cloud options. | Primarily cloud with on-premises option. |
| User Interface | Desktop-based, traditional, customizable. | Mobile/Desktop-based, modern, consistent with Dynamics 365 suite. |
| Integration | Limited cloud service integration. | Seamless integration with Microsoft cloud services. |
| Customization | Highly customizable through development | Customization via extensions, less disruptive upgrades. |
| Cost | Higher initial costs for on-premises. | Lower upfront cost, subscription-based. |
| Target Business Size | Small to medium businesses with complex needs. | Small to medium businesses seeking scalability and extensive integrations. |
| Updates | No | Yes |
| Reporting Capabilities | Restricted | Integration with Power BI |
Conclusion
Choosing between NAV and Business Central depends on your current state (customisations, integrations, risk), your target operating model (cloud vs on-prem), and your appetite for change. If you want a modern cloud-first ERP with strong Microsoft ecosystem integration and a continuous update model, Business Central is typically the better long-term platform. If you rely on deep legacy customisations and need stability while you plan a controlled transition, NAV may be a temporary fit—but it comes with growing platform risk over time. The right choice is the one that aligns with your long-term strategy, supportability requirements, and total cost of ownership over the next 3–5 years.
