Differences between Dynamics NAV and AX

nax_and_axAn often asked question is: What are the differences between Dynamics Nav and AX?

In addition: There is a 3. ERP system provided by Microsoft, Dynamics GP, but this ERP system is only used in the US.

Dynamics Nav and AX are both used around the globe.Both were originally developed by danish companies, Navision and Damgaard (Axapta). The companies merged 2000 and were sold to Microsoft 2002. Microsoft rebranded both ERP systems: Axapta became Dynamics AX, Navision became Dynamics NAV. Both systems are quite successful.

From the historical view AX was mainly used for big companies and/or companies with many branches (sectors). NAV was meant for small and mid sized companies. Nowadays it does not matter, which ERP system you buy, if you do not have one. Both systems use sql server as database. Since vs. 2013 NAV can also be used in big companies with large amount of data, the data connector between Nav and Sql Server works fine since that version. NAV is in many ways easier to use and easier to install. One of the reasons, why NAV is more successful. The finance module is in NAV also better than that one of AX. AX is the choice, if you have many different branches in your company. Both systems can be customized, both can be extended with additional modules. For AX there is a quite long list of localised versions, that one of NAV is quite short. So maybe your country is not on the official list. But i’ve posted a list of localizations developed by nav partners. This list can also be helpful for you to find a capable partner.

A big point is the license model of Microsoft according both ERP systems. Depending on your needs the NAV license could be more expensive than that one of AX (perpetual license). For licensing best contact a partner for license/asset management, e.g. QBS.

Both systems are available in the cloud (azure), Nav earlier than AX. For both systems there are mobile solutions.

Critics about NAV may contain:

  • It’s slow: The windows client (RTC) is not very fast, the base tech (WPF) is too complex, so the rendering of the pages/windows lasts …. the client pcs should have a good graphics device. The number of (open) pages can be very big, because the handling was solved not very good, not very usable, means to navigate can be a challenge. Nav was fast till Nav 2009 Classic Client. There the client used simple windows forms (all was grey and white). The navigation was also better.
  • Reporting is slow and expensive: Customizing/adding classic reports was much easier than now using the sql reports. It’s right, the sql reports (rdlc) are no good tech, slow and the customization lasts about 3 times comparing to an old classic report. The new word reporting did not change the situation.

In general the best is to talk to NAV and AX partners in your region about the special needs of your company. Maybe a partner has a good branch solution and branch knowhow. Also check the terms and costs for customization and maintenance.

Setting up precisions

In Dynamics Nav amount and currency precisions are set on a central point, in the General Ledger Setup. These settings apply for the LCY (Local currency). Foreign currencies are configured in page Currency Card (on base of table Currency).


Fields “Amount Decimal Places”, “Amount Rounding Precision”, “Unit-Amount Decimal Places” and “Unit-Amount Rounding Precision” are maybe missing in this page. In the standard page they are not shown. In that case adde them to the page in the development environment.


In the currency card you can configure foreign currencies. Here you find the same fields to set the precision as in the general ledger setup. This is also the place to set/update the exchange rates.

For details about the fields in G/L Setup follow

For details about the fields in the Currency Card follow

Additional it’s possible to activate automatic invoice rounding:
To make sure that sales and purchase invoices are rounded automatically, you must activate the invoice rounding function. In the Search box, enter Sales & Receivables Setup or Purchases & Payables Setup, open the page, on the General FastTab, select the Invoice Rounding check box. You can activate invoice rounding separately for sales and purchase invoices.

Localisations for NAV

Localizations for specific countries are quite often an issue. Microsoft provides only a couple of localizations: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Great Britain, Iceland, India*, Italy, Mexico, Netherlands, New Zealand, Norway, Russia*, Spain, Sweden, Switzerland, United States.

* The supported countries can differ between the Nav versions.

The complete lists you’ll find here.

For countries, where there is no localization, best start with Dynamics Nav W1 version. This is the base version of Dynamics Nav, contains no localization at all. So it can be used in every country, but needs a couple of customizations according to national laws, e.g. changes in the accounting/finance area, new and customized reports a.s.o. Additional you’ll may need a new language layer. For that look for a Nav partner located in your region, start with Pinpoint.

Following a list of Nav Partners, who have developed additional localizations. This list will be periodically updated:


  • Slovenian Nav Partner Business Solutions d.o.o., also known for their great Permission & Role Wizard for Nav 2009, has developed Nav 2013 localizations for following countries: Slovenia, Croatia, Serbia, Bosnia and Herzegovina, Montenegro, Macedonia, Kosovo. Included are additional functionalities and tools. They provide the localizations in 3 packages: basic, extended, integrated. Maybe they also have developed localizations for the newer Nav versions. If you need it, contact them directly.

Compare Dynamics Nav Versions

Sometimes it’s needed to compare the features of different Nav versions, especially in scenarios, where there is a decision: Upgrade or not?

For that MS has debveleoped a very helpful site: The MS Dynamics Nav Feature Comparision Tool.

You can find it here.

You get relevant information not only about the main feature topics. You get also detailed info about modules and features, also about Licensing. Especially interesting is the View “Compare all”. This is the overview, which can be an important decision helper for questions:

  • Which nav version fits best for my company
  • Should i upgrade the current nav version? To which version?
  • Which features do i get with a special Nav version as against Dynamics AX, SAP or an other ERP System.
