Dynamics NAV (Navision) vs Business Central: Key Differences

Dynamics NAV vs Business Central is one of the most common questions we get from companies still running Navision. The short answer: Business Central is the next version of Dynamics NAV — same family, same accounting DNA — but rebuilt as a cloud service with a different licensing model, a browser interface, automatic updates, Copilot, and a completely different way of customizing the system. If you’re on Navision today, this article explains what’s actually different, which NAV versions are still supported, and whether you should upgrade now or can safely wait.

This is the comparison. If you’ve already decided to move and want the step-by-step how-to — upgrade routes, phases, costs, checklist — go straight to our complete NAV to Business Central migration guide.

Is Navision the Same as Business Central?

Not quite — but close. Think of it as one product line with three names:

• Navision is the original Danish ERP, first released in the late 1980s.
• Microsoft Dynamics NAV is what Navision became after Microsoft bought the company in 2002 and rebranded it in 2005.
• Dynamics 365 Business Central is NAV’s successor, launched in 2018 as a cloud service.

If NAV served your business well, Business Central will feel familiar. The chart of accounts, dimensions, posting groups, customer and vendor ledgers, the Quote → Order → Shipment → Invoice document flow — all recognizably the same. What changed is everything around that core: where it runs, how you pay for it, how it’s updated, and how it’s customized.

That’s why “is Navision the same as Business Central?” gets two honest answers. Functionally, mostly yes. Technically and commercially, no.

From Navision to NAV to Business Central: A Short History

The key date for anyone comparing the two is 2019. Until Business Central 14, a BC system could still be customized the NAV way. From version 15 onward, the base application itself is an AL extension, and C/AL is gone for good.

Dynamics NAV vs Business Central: Side-by-Side Comparison

The Key Differences, Explained

1. Deployment: from your server room to Microsoft’s cloud

NAV lives on your servers. You pay for the hardware, Windows Server and SQL Server licences, backups, patching, remote access — and the phone call when it goes down at month-end.

Business Central online runs on Azure. Microsoft handles uptime, backups, security patching and disaster recovery. You open a browser. On-premises Business Central still exists for companies with regulatory or contractual reasons to host their own data, but it’s the minority option — and some newer capabilities, especially Copilot features, are cloud-only.

2. Licensing: perpetual vs subscription

NAV was typically bought once, with an annual enhancement plan to stay entitled to upgrades. Business Central online is a subscription:

• Essentials — $80/user/month: finance, sales, purchasing, inventory, warehousing, projects
• Premium — $110/user/month: everything in Essentials plus manufacturing and service management
• Team Members — $8/user/month: read access, approvals, light data entry

These are US list prices after Microsoft’s November 2025 increase; euro prices vary by country. The practical difference: NAV licensing rewarded buying full licences for everyone, while BC lets you put occasional users on Team Member licences. Many NAV customers end up with fewer full licences than they had on NAV.

3. User interface

The NAV Windows client was fast for power users but tied to a Windows machine (or Remote Desktop). Business Central’s web client runs in any browser and adapts to tablets and phones. It has role centers, personalization, a search bar that replaces menu-diving, and Excel/Outlook add-ins. Expect a two-to-four-week adjustment period for long-time NAV users — then most don’t want to go back.

4. Extensions (AL) vs code modifications (C/AL)

This is the difference that matters most for your budget.

In NAV, partners customized the system by editing Microsoft’s own objects in C/AL. That made NAV extremely flexible — and made every upgrade a code-merge project. It’s the main reason so many companies are still on NAV 2009 or 2013: upgrading their customizations was too expensive.

In Business Central, customizations are AL extensions: separate packages that add fields, pages, logic and reports on top of the standard application without changing it. Microsoft updates the base, your extensions keep working. The catch for NAV customers: C/AL code can’t be imported. Every customization has to be retired, replaced by an AppSource app, or rewritten in AL — typically 30–50% can simply be retired because standard BC now covers it.

5. Updates

NAV stays exactly where you installed it. Business Central online receives two major release waves a year (April and October) and monthly updates in between. You can schedule the update window, but you can’t stay on an old version forever. That’s the trade: you give up control over timing, and in return you never face another multi-month upgrade project.

6. Copilot and AI

NAV has no AI. Business Central includes Copilot in the standard product: drafting item descriptions, helping with bank reconciliation, analysing data in lists, answering questions in chat, and — in recent releases — agents such as the Sales Order Agent that process routine work for you. Most Copilot features are included in the BC licence; some agent capabilities are billed on consumption. See our Sales Order Agent walkthrough for what an agent looks like in practice.

7. Power Platform and Microsoft 365

Business Central is designed to be part of Microsoft 365: an Outlook add-in to create quotes and invoices from email, Excel editing of lists, record links and cards in Teams (internal users with eligible Microsoft 365 licences can view BC data in Teams without a BC licence), Power BI apps, and Power Automate and Power Apps connectors. In NAV, every one of these was a custom integration project.

Dynamics NAV Support End Dates

Per Microsoft’s lifecycle pages (NAV follows the Fixed Lifecycle Policy):

NAV 2009 and older are long out of support. “Extended support” means security fixes only — no new features, no regulatory updates. For companies in countries with fast-moving e-invoicing and tax reporting requirements (Romania’s e-Factura and SAF-T are good examples), that gap usually bites long before the official end date.

Should You Upgrade? Who Should Move — and When It’s OK to Wait

Move now if:

• You’re on NAV 2016 or older. You’re already unsupported. Every month adds security and compliance risk.
• You’re on NAV 2017. Support ends in January 2027. A standard migration takes 3–5 months — the planning window is now.
• Compliance changes keep costing you. E-invoicing, SAF-T, new VAT rules: in NAV, each one is a custom project; in BC, most arrive through localization updates.
• Your servers are due for replacement. Don’t buy new hardware for a system you’ll leave in two years.
• Your partner has gone quiet or the only person who understands your customizations is about to retire.

It’s OK to wait (for now) if:

• You’re on NAV 2018, it’s stable, and your processes haven’t changed. You’re supported until January 2028. Use the time to clean data and decide which customizations you still need — but have a project plan by early 2027.
• You’re in the middle of another big change — an acquisition, a new warehouse, a year-end audit. Don’t stack projects. Pick the next quiet window.
• You’re considering a different ERP entirely. Fine — but make the decision deliberately, not by default.

What’s not a good reason to wait: “it still works.” NAV will keep working right up to the day you need a security patch, a regulatory change, or an integration it can’t support.

What Does Moving to Business Central Cost?

A rough signal, based on our NAV migrations:

Microsoft subscription licences come on top: a 20-user company with 8 Essentials, 2 Premium and 10 Team Members pays about $940/month at US list prices. Compared with a NAV enhancement plan plus server costs, many customers end up close to what they already pay.

As a rule of thumb, moving from NAV costs 50–70% of a brand-new Business Central implementation of the same scope, because the data model and processes are familiar. The biggest variable is how much C/AL customization you have. Full breakdown in our Business Central implementation costs guide.

How the Upgrade Works (in One Paragraph)

There’s no upgrade button. Microsoft’s route goes from NAV to Business Central 14 on-premises, then to a current version, then to the cloud via the Cloud Migration tool — older NAV versions need extra hops first. Many NAV 2009 and 2013 customers skip that chain and do a reimplementation with selective data migration instead. Either way, customizations are triaged (retire, replace, rewrite in AL), data is cleaned and migrated in dry runs, and users are trained before a weekend cutover.

The full, phase-by-phase version — upgrade routes by NAV version, what breaks, timelines, a prep checklist, and a section on Dynamics AX — is in our NAV to Business Central migration guide.

FAQ

Is Navision the same as Business Central?

Same family, not the same product. Navision became Microsoft Dynamics NAV in 2005, and Business Central (2018) is NAV’s cloud-era successor. The accounting core is recognizably the same; the platform, interface, licensing and customization model are different.

What is the main difference between Dynamics NAV and Business Central?

NAV is on-premise software with a perpetual licence and C/AL code modifications. Business Central is primarily a SaaS subscription with a browser interface, automatic updates, built-in Copilot, and customizations delivered as AL extensions.

Is Dynamics NAV still supported?

Only NAV 2017 (until January 2027) and NAV 2018 (until January 2028), and only with security fixes. NAV 2016 support ended in April 2026; everything older is fully unsupported.

Can Business Central run on-premises like NAV?

Yes, but the cloud version is the default, gets some features first or exclusively, and removes server maintenance. Most NAV customers move to the cloud.

How much does it cost to move from NAV to Business Central?

Partner fees range from €8,000–18,000 for a clean NAV 2016–2018 to €45,000–60,000+ for complex multi-entity migrations. Licences are $80 (Essentials), $110 (Premium) and $8 (Team Members) per user per month at US list prices.

Should I upgrade now or wait?

On NAV 2016 or older: now. On NAV 2017: now, support ends in January 2027. On a stable NAV 2018: you can wait a little, but plan the project at least 6–12 months before January 2028.
