Slovak eInvoice Solution for Older Microsoft Dynamics NAV Versions

1 Jul, 2026

The upcoming mandatory electronic invoicing (eInvoice) legislation in Slovakia will require companies to exchange invoices electronically in accordance with government regulations.

Many businesses, however, continue to rely on older versions of Microsoft Dynamics NAV that are stable, reliable, and fully support their daily operations.

If you are using:

  • Microsoft Dynamics NAV 4.0
  • Microsoft Dynamics NAV 5.0
  • Microsoft Navision 2009
  • or any other legacy version of Microsoft Dynamics NAV

there is no need to migrate immediately to Microsoft Dynamics 365 Business Central just to comply with the new eInvoice requirements.

eInvoice Compliance Without a Full ERP Upgrade

At 4B Software, we are developing a solution that enables Slovak eInvoice compliance for older Microsoft Dynamics NAV installations.

Our goal is to allow companies to:

  • generate electronic invoices compliant with Slovak legislation,
  • communicate with the Slovak national eInvoice platform,
  • keep their existing NAV business processes,
  • minimize changes to their ERP system,
  • postpone expensive ERP migrations.

Who Is This Solution For?

This solution is ideal for companies that:

  • still operate older Microsoft Dynamics NAV versions,
  • have heavily customized NAV environments,
  • are not ready to migrate to Business Central,
  • need to comply with Slovak legislation quickly and cost-effectively.

Extensive Microsoft Dynamics NAV Experience

At 4B Software, we have more than 15 years of experience developing, customizing, and integrating Microsoft Dynamics NAV solutions.

Our experience with legacy NAV versions allows us to build reliable integrations that extend the life of existing ERP systems while meeting modern legislative requirements.

Prepare for the New Legislation Today

The Slovak eInvoice system will be introduced gradually, and companies should prepare well in advance to ensure a smooth transition.

If your company is running an older version of Microsoft Dynamics NAV, we would be happy to discuss the available options and propose the most suitable solution for your environment.

Contact 4B Software today to learn how your Microsoft Dynamics NAV system can become compliant with the Slovak eInvoice legislation—without the need for an immediate ERP upgrade.
