Microsoft Dynamics NAV – originally known as Navision – was Microsoft's flagship ERP solution for small and mid-sized businesses. For more than two decades, it gave organizations a centralized platform for managing finance, operations, supply chain, manufacturing, and more. At its core, NAV was designed to help growing businesses bridge the gap between basic accounting software and large enterprise ERP systems.
Today, NAV is a legacy product. Microsoft has ended new license sales and is winding down support across all versions. The platform's direct successor is Dynamics 365 Business Central, which launched in 2018 and carries forward much of NAV's functionality in a modern, cloud-native architecture. Most businesses researching Dynamics NAV in 2026 are current users weighing their options – not prospective buyers.
If your organization is still running NAV, this guide covers what you need to know: what the platform does, where support stands today, and how to evaluate a path forward.
Microsoft no longer sells new Dynamics NAV licenses. Mainstream support has ended for every version ever released. Only NAV 2017 and NAV 2018 remain under Microsoft's extended support phase, and both windows are closing.
| Version | Mainstream Support End | Extended Support End | Status (as of April 2026) |
| NAV 2009 | January 2015 | January 2020 | End of Life |
| NAV 2013 | January 2018 | January 2023 | End of Life |
| NAV 2015 | January 2020 | January 2025 | End of Life |
| NAV 2016 | April 2021 | April 2026 | End of Life |
| NAV 2017 | January 2022 | January 2027 | Extended Support Only |
| NAV 2018 | January 2023 | January 2028 | Extended Support Active |

When a NAV version exits extended support, Microsoft stops issuing security patches, bug fixes, and compliance updates for that version. For businesses still running it, this creates three compounding risks:
Yes – technically. Microsoft does not force businesses off NAV when support ends. Existing installations continue to operate. However, your organization assumes full responsibility for security, compliance, and stability once Microsoft stops issuing patches. Many businesses in this position work with a certified NAV partner like IES for ongoing support, custom patching, and migration planning.
No. Microsoft no longer sells new Dynamics NAV licenses. If your organization needs an ERP solution today, Microsoft's current offering for the SMB market is Dynamics 365 Business Central. For authoritative lifecycle dates, see Microsoft's official product lifecycle page.
Despite its legacy status, NAV remains in active use across thousands of organizations worldwide. Understanding what it was built to do helps businesses evaluate whether their current setup still meets their needs – and where gaps are starting to appear.
NAV is an end-to-end ERP designed to give SMBs greater control across core business functions:
One of NAV's strengths was its modular design. Businesses could start with a few core functions and expand over time. It also supported integration with Office 365 and a range of third-party tools – though maintaining those integrations has grown more difficult as Microsoft's ecosystem has evolved around Business Central.
Microsoft Dynamics NAV consists of multiple modules designed to handle specific business functions.
The finance module handles everyday financial transactions used in business, including:
Businesses gain better control over the management of company finances. You can also use the financial information stored in the database to help spot industry trends and plan future strategies.
The project management module allows users to perform common tasks like configuring jobs, scheduling resources, and information gathering for budget management. Organizations can also track employee hours using built-in timesheets. In addition, project managers can get an overview of items like:
With the Supply Chain Management functions available within Microsoft Dynamics Nav, organizations can reduce redundant tasks. In addition, the platform helps companies improve accuracy through automation while cutting down on overhead and handling time.
The ERP gives your company control over the entire supply chain. Your organization can build a customized view of all supply chain activities, including:
Real-time data insights help with essential business processes like keeping up with supplier statuses, what’s happening in production plants, and the day-to-day functions within distribution centers.
The Microsoft Dynamics NAV platform provides employees working in sales and marketing with the tools necessary to obtain accurate customer information. In addition, teams can easily access and manage contacts and networks. Marketing can set up campaigns targeted at core audiences while improving customer relations.
Your sales and marketing teams can streamline business tasks related to:
Even small companies typically take in a large amount of data each day. Dynamics NAV Intelligence and Reporting provides features that help companies collect, analyze, and share data related to:
Dynamics NAV’s Business and Intelligence functions help users deliver meaningful insights across the entire organization. Analysts can design a dashboard that gives them a 360-degree view of essential business workflows. In addition, users can create reports containing detailed information to help management make critical business decisions.
In addition to core financial and project management functions, Microsoft Dynamics NAV software supports robust warehouse and manufacturing management modules that enable process optimization across the production lifecycle.
Warehouse management features in NAV help users:
When integrated with Navision inventory management tools, companies gain real-time visibility into stock levels, reorder points, and product movement — all essential for just-in-time operations.
For manufacturers, Dynamics NAV manufacturing functionality supports:
These tools make NAV particularly attractive for SMBs in industries such as light manufacturing, food production, and electronics.
For teams still working in NAV, the Role Center is where most daily work begins. When you log in, NAV presents a personalized dashboard tailored to your assigned role – whether that is an accountant, a warehouse manager, or a sales representative. This section provides a high-level walkthrough of how NAV is structured and how key workflows operate.
The Role Center is your home base. It surfaces tasks, reports, and KPIs relevant to your role. Use the navigation menu across the top to move between modules – finance, sales, purchasing, inventory, and so on. The search bar (accessible via the magnifying glass icon or Ctrl+F3 in most versions) lets you locate any page, report, or record in the system quickly.
In the Finance module, navigate to Financial Management > General Ledger > Chart of Accounts. Here you can view your account structure, post journal entries, and run G/L analysis. NAV uses account categories and subcategories to organize financial data, which feeds directly into financial statements and budget comparisons.
Navigate to Sales & Marketing > Order Processing > Sales Orders. Create a new order by selecting a customer, adding line items (items, resources, or G/L accounts), and specifying quantities and pricing. Once confirmed, the order can be posted to generate a shipment and invoice. NAV automatically updates inventory levels and accounts receivable.
Go to Warehouse > Items to access your item master. Each item record stores pricing, costing method, unit of measure, reorder settings, and current stock levels. Use item journals to adjust quantities and reconcile physical counts with system records. NAV also supports lot and serial number tracking for businesses that need item-level traceability.
NAV includes a built-in report library under each module. Common reports include the Trial Balance, Aged Accounts Receivable, Inventory Valuation, and Customer/Vendor statistics. Reports can be filtered by date, dimension, or location and exported to Excel. Account schedules allow custom financial statement layouts for more advanced analysis.
Note: If your organization is running a version of NAV that has reached end of support, some reporting functionality may produce unexpected results as underlying data structures diverge from newer integrations. This is one of the most common friction points IES hears from businesses evaluating migration.
With NAV support winding down, migration to Dynamics 365 Business Central is the most common path forward for current NAV customers. Microsoft designed Business Central as NAV's direct evolutionary successor – built on the same data model, with significant architecture improvements and a fully cloud-native deployment option.
Business Central is Microsoft's current ERP for small and mid-sized businesses. It delivers the same core functionality as NAV – finance, supply chain, manufacturing, project management, and sales – while adding cloud infrastructure, automatic updates, native Microsoft 365 and Teams integration, and Microsoft Copilot AI capabilities. It can be deployed in the cloud, on-premises, or in a hybrid configuration.
| Dynamics NAV | Dynamics 365 Business Central | |
| Availability | No longer sold; existing installs only | Actively sold and supported by Microsoft |
| Deployment | On-premises only | Cloud, on-premises, or hybrid |
| Support status | Ending; NAV 2018 extended ends Jan 2028 | Ongoing with regular Microsoft updates |
| Updates | Manual; managed by customer or partner | Automatic in cloud; manual on-prem |
| User licensing | Concurrent user or Limited User license | Named user; Team Member tier available |
| Microsoft 365 | Limited integration | Deep, native integration |
| AI / Copilot | Not available | Microsoft Copilot built in |
| Mobile access | Limited | Native mobile-friendly interface |
| License model | Perpetual (on-prem) or subscription | Subscription (cloud) or perpetual (on-prem) |
Organizations moving from NAV to Business Central generally have three migration paths to consider:
The right path depends on the version of NAV you are running, the degree of customization in your environment, the quality of your data, and your timeline and budget. IES has guided organizations through all three approaches and can help assess which option fits your situation.
Not all Microsoft partners have deep NAV expertise. When evaluating a partner, look for:
IES has worked with every version of Microsoft Dynamics, from legacy NAV environments to current Business Central implementations. Whether your priority is extending the life of your current NAV setup or planning a migration, our team can help you build a plan that fits your business.
Migration costs vary based on several factors:
Business Central is licensed per named user on a monthly subscription basis. Essentials and Premium tiers are available, with Premium adding manufacturing and service management capabilities. Contact IES for a consultation; we can assess your environment and provide a realistic estimate based on your specific situation.
While NAV is traditionally an on-premises ERP, organizations are increasingly interested in dynamics nav cloud deployments. Although NAV itself doesn’t offer native cloud support like Dynamics 365, it can be hosted in private or hybrid cloud environments through Microsoft Dynamics NAV partners like IES.
Benefits of NAV in the cloud include:
However, full cloud-native ERP experiences — like seamless updates, mobile-friendly interfaces, and AI-driven insights — are only available through Business Central.
