If your business is still running Microsoft Dynamics NAV, deciding whether to move to Dynamics 365 Business Central is not simply a question of replacing an old ERP with a new one.
The more important question is whether your current NAV environment can support your business over the next several years, and whether Business Central provides enough operational value to justify the investment.
Dynamics 365 Business Central is Microsoft's current ERP platform for small and midsized businesses and the successor to Dynamics NAV. It retains many of NAV's core capabilities while introducing modern cloud deployment, web and mobile access, Microsoft 365 integration, Power Platform, analytics, automation, AL extensions, and Microsoft Copilot.
That does not mean every NAV customer needs to migrate immediately. A stable, supported NAV environment may still be suitable. The decision should consider your NAV version, support status, customizations, integrations, infrastructure, security requirements, users, data, and long-term business strategy.

What Is Dynamics NAV?
Microsoft Dynamics NAV originated from Navision, which Microsoft acquired in 2002. It became a widely used ERP platform for small and midsized businesses, supporting finance, accounting, sales, purchasing, inventory, manufacturing, warehousing, projects, and service operations.
NAV's flexibility was one of its biggest strengths. Businesses and Microsoft partners could customize the system extensively to support specialized processes.
That flexibility could also create complexity. Long-running NAV environments often accumulated custom code, modified reports, third-party applications, integrations, and manual workarounds.
For that reason, the age of NAV alone does not determine whether migration is necessary. The specific version and environment matter.
What Is Business Central?
Dynamics 365 Business Central is Microsoft's current ERP platform for small and midsized businesses.
It supports finance, sales, purchasing, inventory, manufacturing, warehousing, projects, service management, and supply chain operations while connecting more closely with Microsoft's wider technology ecosystem.
Business Central is available as Business Central Online and Business Central On-premises. Online reduces the amount of infrastructure the customer needs to manage directly, while On-premises provides greater control over the deployment environment.
Business Central Online follows Microsoft's continuous update model, with major updates twice a year and additional minor updates.
Is Business Central the Same as NAV?
No. Business Central is the successor to Dynamics NAV, but it is not simply NAV with a new name.
The products share significant ERP heritage, which is why NAV users often find many business concepts familiar. However, Business Central uses a modern technology and development architecture designed around cloud services, extensions, web access, Microsoft 365, Power Platform, and AI.
Traditional NAV development commonly used C/AL. Current Business Central development uses AL and an extension-based model.
What Are the Main Differences Between NAV and Business Central?
Cloud, Accessibility and User Experience
Traditional NAV environments were commonly hosted on customer or partner-managed infrastructure, although deployment varied by version.
Business Central Online provides browser-based access and reduces the need to manage ERP servers and platform infrastructure directly.
Business Central also provides mobile access, which can be useful for managers, sales teams, warehouse staff, and employees working away from the office.
The distinction is not simply "NAV is on-premises and Business Central is cloud." Business Central also has an On-premises deployment option.
Microsoft 365, Power Platform and AI
Business Central has much stronger alignment with Microsoft's current ecosystem.
Depending on configuration, organizations can connect Business Central with Excel, Outlook, Teams, Power BI, Power Automate, and Power Apps.
Business Central also provides Microsoft Copilot capabilities for selected tasks involving productivity, analysis, and content generation.
NAV can integrate with Microsoft technologies and external AI services, but these capabilities depend heavily on the NAV version and typically require additional development or integration.
Customization and Development
Traditional NAV implementations often modified the application directly using C/AL. Those modifications could make future upgrades more complex.
Business Central uses AL extensions, providing a more structured way to extend the application while keeping custom functionality separate from Microsoft's standard application.
That does not eliminate technical debt. Poorly designed extensions and excessive customization can still make a Business Central environment difficult to maintain.
Reporting and Analytics
NAV can support sophisticated reporting, particularly when customized or connected to external BI tools.
Business Central's advantage is its closer integration with the current Microsoft analytics ecosystem, particularly Excel and Power BI.
The difference is not that NAV cannot report. Business Central simply provides a more modern platform for connecting ERP data with analytics and decision-making.
NAV vs. Business Central Pricing: Which Costs More?
There is no universal answer. Business Central may reduce infrastructure and platform-management costs, but subscription fees and migration costs must be included in the calculation.
How Much Does Business Central Cost in the USA?
Microsoft's current U.S. list pricing is:
| License | Price | Typical Use |
|---|---|---|
| Essentials | $80/user/month, paid yearly | Core ERP functionality |
| Premium | $110/user/month, paid yearly | Essentials plus manufacturing and service management |
| Team Members | $8/user/month, paid yearly | Limited-access users |
| Device | $45/device/month | Shared-device scenarios |
Microsoft's published U.S. pricing lists Essentials at $80 and Premium at $110 per user/month when paid yearly.
Microsoft announced the current $45 Device price effective November 1, 2025.
Actual commercial terms can vary, so businesses should confirm current pricing and licensing requirements before purchasing.
Is Business Central Cheaper Than NAV?
Not necessarily.
An NAV environment may have existing perpetual licenses but also ongoing expenses for servers, databases, backups, support, IT administration, upgrades, security, customizations, and third-party applications.
Business Central replaces some of those costs with recurring subscription fees, while migration introduces implementation, data migration, integration, training, and potentially customization costs.
The meaningful comparison is total cost of ownership, not license price alone.
Should You Upgrade From NAV to Business Central?
You should seriously evaluate Business Central when NAV is becoming a constraint on supportability, security, growth, integration, user productivity, or technology strategy.
Migration becomes particularly worth investigating when your NAV version is aging, infrastructure costs are increasing, customizations are difficult to maintain, or your business needs cloud access, modern analytics, Microsoft 365, Power Platform, or AI capabilities.
A supported NAV environment that still meets business requirements may not require an immediate move.
How Does NAV to Business Central Migration Work?
NAV migration is not simply a database copy. The migration path depends on the NAV version, customizations, data, and deployment architecture.
Microsoft's supported migration approaches can require moving through Business Central On-premises before migrating to Business Central Online. Older NAV versions may require additional upgrade steps.
Businesses can generally consider a full migration that carries forward required data and customizations, or a reimplementation that creates a cleaner Business Central environment and migrates only the data the business genuinely needs.
The right approach depends on the existing NAV environment.
What We Learned from a NAV 2018 to Business Central Upgrade in the USA
A real Dynamics Square USA project with Adams Recycling illustrates why the migration decision needs to go beyond software versions.
We worked with Adams Recycling, a recycling and materials recovery organization in South Carolina that was running NAV 2018 for finance, purchasing, inventory, warehouse operations, and sales. The organization was dealing with an unsupported NAV environment, server-dependent infrastructure, limited Microsoft 365 connectivity, an outdated user experience, and difficulty scaling the system for future requirements.
Rather than simply reproduce the existing NAV environment, we approached the upgrade around Adams Recycling's operational needs.
We upgraded from NAV 2018 to Business Central SaaS, covering finance, procurement, inventory, warehouse activities, and basic sales. We also introduced structured reporting, approval processes, Microsoft 365 integration, and preparation for future Power BI reporting.
The result was a cloud-based environment that removed dependence on local servers, improved operational visibility, reduced repetitive manual work, and provided a foundation for future expansion.
For us, the important lesson from the project was that a successful NAV upgrade is not simply about moving data from one system to another. It is about understanding why the existing environment is holding the business back and what the new ERP needs to accomplish.
Should You Recreate Every NAV Customization?
No. Every customization should be assessed before it is rebuilt.
In our experience, some NAV customizations were created years ago to solve limitations that Business Central can now address through standard functionality.
We therefore ask:
Why does this customization exist?
Who uses it?
What business problem does it solve?
Does Business Central already handle the requirement?
The answer may be configuration, an AL extension, a Business Central app, Power Platform, or no customization at all.
This approach can reduce technical debt and prevent businesses from spending money reproducing processes they no longer need.
What Happens to NAV Data During Migration?
Not all historical NAV data necessarily needs to become operational data in Business Central.
Businesses should determine what needs to be migrated, what should be cleaned, and what can remain in an accessible archive or reporting environment.
Microsoft also documents a reimplementation approach for organizations that want to move essential data without carrying forward the complete legacy application and its customizations.
In our experience, migration is a good opportunity to remove obsolete customers, vendors, items, dimensions, duplicate records, and other accumulated data rather than carrying unnecessary complexity into the new ERP.
NAV vs. Business Central: Which ERP Is Right for Your Business?
Business Central is generally the stronger long-term choice for organizations that want Microsoft's current SMB ERP platform and need cloud access, modern analytics, Microsoft 365 integration, Power Platform, automation, or AI capabilities.
NAV can still make sense for businesses with stable, supported environments that do not currently need those capabilities.
The decision should come down to your NAV version, support lifecycle, customizations, integrations, infrastructure costs, security requirements, data, users, and five-to-ten-year business strategy.
For many organizations, moving to Business Central is more than an ERP upgrade. It is an opportunity to remove unnecessary customizations, modernize integrations, clean up data, improve reporting, and redesign outdated processes.
The best migration is not the one that reproduces NAV most accurately. It is the one that preserves what the business needs, removes what it no longer needs, and creates a more sustainable ERP environment for the future.
If your organization in the USA is evaluating whether to stay on NAV or move to Business Central, the first step does not have to be a migration. It can simply be an assessment of whether migration makes technical and financial sense.
Why You Should Choose Dynamics Square USA for Business Central Upgrade?
NAV migration requires knowledge of both the legacy environment and modern Business Central. The implementation partner needs to understand what can be retained, what should be redesigned, and what should be retired.
