Could Your Dynamics NAV Costs Be More Than You Realise?

Microsoft Dynamics NAV has supported finance and operational teams successfully for many years. If the system still completes the work you need it to do, continuing with it may appear to be the least expensive option.

However, the true cost of an ageing ERP system is not limited to its annual licence or support invoice.

It can also include the time spent maintaining servers, producing reports manually, entering information more than once, managing fragile integrations and supporting bespoke developments that few people fully understand. These costs are often spread across different departments, which can make them difficult to see.

At the same time, Microsoft has confirmed important changes to the future of Dynamics NAV. Extended support for the final NAV version ends in January 2028. From 30th April 2031, NAV customers will no longer be able to renew annual Service Plans or subscription licences, purchase additional perpetual users for existing deployments or continue subscription use through SPLA. Your system will not suddenly stop working on those dates, but the commercial and technical options available to you will become more limited.

This makes now a sensible time to build a clearer picture of your current Dynamics NAV costs and whether Microsoft Dynamics 365 Business Central could provide better long-term value.

What Are the Hidden Costs of Staying on Dynamics NAV?

Every NAV environment is different. Some are relatively standard, while others have accumulated years of bespoke development, reporting tools, integrations and workarounds.

A useful cost review should therefore consider more than software licensing.

Ageing Infrastructure and Server Costs

Many Dynamics NAV systems continue to run on premises. This means the organisation, or its technology provider, must continue to manage areas such as:

Servers and related hardware
Hosting or data centre costs
Backups and recovery arrangements
Operating system maintenance
Security management
Capacity and storage
Infrastructure upgrades
Remote access arrangements

The cost is not only financial. Internal IT teams and external providers must spend time maintaining the environment, monitoring its reliability and resolving compatibility issues.

Business Central online is delivered as a cloud service. This can reduce the need to own and maintain the underlying ERP infrastructure, while providing access to the current version of the platform through regular product and security updates.

This does not mean that every NAV customer will automatically spend less by moving. It means the comparison should include the full cost of infrastructure and technical management, rather than comparing a NAV maintenance invoice with a Business Central subscription in isolation.

The Cost of Manual Workarounds

Ageing systems rarely fail all at once. More commonly, small gaps appear between what the system provides and what the business now needs.

Teams may respond by:

Re-entering information into another application
Tracking approvals through email
Exporting data into spreadsheets
Maintaining separate departmental records
Reconciling several versions of the same report
Completing additional checks because systems are not connected

Each workaround may appear manageable. Collectively, they can consume a substantial amount of employee time and make processes more dependent on individual knowledge.

A review of Business Central should therefore consider where connected processes, workflows and closer integration with Microsoft applications such as Outlook, Excel and Teams could reduce duplicated effort.

Reporting That Takes Too Long to Produce

If management information depends on exporting NAV data, correcting it manually and combining several spreadsheets, the cost includes more than the time needed to prepare the report.

There may also be:

Delays in obtaining current information
Multiple versions of the same figures
Additional checking and reconciliation
Reduced confidence in reports
Dependence on employees who understand complicated spreadsheets

Business Central provides reporting and analysis capabilities within a connected cloud platform and can work with technologies such as Power BI. The potential benefit is not simply a more attractive dashboard. It is the ability to spend less time preparing information and more time using it to make decisions.

Bespoke Development That Is Expensive to Maintain

Bespoke functionality is often one of the main reasons organisations delay moving from NAV. These developments may support highly important processes and represent a significant historic investment.

However, keeping every customisation can also have a cost. Older developments may require specialist knowledge, make upgrades more complicated or duplicate functionality that is now available through Business Central or an established application.

A migration assessment should establish:

Which developments are still being used
What business need each one addresses
Whether Business Central now provides equivalent functionality
Whether a supported application is available
What genuinely needs to be redeveloped
Which modifications can be retired

This is not about discarding valuable functionality. It is about avoiding the cost of reproducing historic complexity without first checking whether it remains necessary.

Synergy Technology can support migration, re-implementation and combined approaches. The right route depends on your current version, data, processes, integrations and objectives. Our migration versus re-implementation guide explains the main considerations.

Integrations That Become Harder to Support

Your NAV system may exchange information with ecommerce, CRM, warehousing, payroll, reporting, banking, manufacturing or other specialist applications.

As the surrounding technology changes, an older integration may require more work to keep running. A change in one system can lead to extra development, manual intervention or repeated fault finding elsewhere.

When reviewing the cost of NAV, consider:

What each integration costs to support
How often it requires manual attention
Whether it prevents another system from being upgraded
How failures affect employees and customers
Whether information is being duplicated
Whether a more supportable connection is available

Business Central is designed to work with the wider Microsoft environment and can be extended through applications and integrations. The financial opportunity lies in simplifying the technology landscape where appropriate, not in replacing every existing connection without a clear business reason.

Dependence on Individual People

Over time, knowledge of NAV customisations, reports and processes can become concentrated among a small number of employees or consultants.

If only one person knows how to produce an essential report or resolve a recurring issue, this represents a business continuity risk. There may also be a cost when new employees need lengthy training or specialist knowledge becomes harder to source.

A NAV review provides an opportunity to document these dependencies, understand where they affect the business and decide how they should be addressed during a move to Business Central.

Delaying Change Until It Becomes Urgent

Microsoft’s 2031 licensing changes may feel some distance away, but leaving the decision until later could reduce your options.

An ERP migration can involve:

Reviewing existing processes
Assessing bespoke developments
Cleaning and preparing data
Mapping integrations
Testing business-critical activities
Training users
Planning the cutover
Supporting teams after launch

Beginning with a review does not commit you to an immediate migration. It gives you the information needed to plan around your business priorities, budget and operational calendar rather than allowing an external deadline to dictate the project. Microsoft is explicitly encouraging Dynamics NAV customers to begin evaluating their long-term ERP strategy ahead of the January 2028 support endpoint and the licensing changes taking effect on 30th April 2031.

How Can Business Central Help Reduce Dynamics Nav Costs?

Moving to Business Central involves an implementation investment, so it is important to build a balanced business case rather than assume that cloud software will automatically be cheaper.

Depending on your existing environment, potential areas of value may include:

Reduced reliance on on-premises ERP infrastructure
Less time spent maintaining servers and arranging upgrades
More predictable subscription costs
Fewer manual processes and duplicated entries
Better-connected finance and operational information
Reduced dependence on unsupported bespoke functionality
Easier access to current reporting
Regular platform updates
Closer integration with Microsoft 365
The ability to add users and functionality without equivalent infrastructure changes

These benefits should be assessed against your own baseline. This means documenting what you currently spend on licences, support, hosting, infrastructure, development and related applications, as well as the employee time absorbed by workarounds and reporting.

What Can Real Business Central Projects Achieve?

A useful business case should be supported by evidence from organisations that have faced similar decisions.
