What are the Risks of not upgrading to Business Central?

What if dynamics NAV goes down tomorrow?
If you’re using NAV 2013 R2 or earlier, you’re no longer supported by Microsoft. This means no bug fixes and no improvements. Of course, you can contact your current partner for change requests and how-to queries, but what happens when the issue is with the product itself and needs to be escalated to the same team that built it?
What if your next upgrade costs 40% more?
The longer you leave it to upgrade Dynamics NAV, the more it’s likely to cost you. Microsoft is currently bridging the gap with discounts and incentives for existing NAV customers to upgrade to Business Central, but this won’t always be the case.
If you’ve not been paying your BREP (Business Ready Enhancement Plan), it can get even more expensive. To take advantage of free licenses when you upgrade, you’ll need to repay your BREP at 16% per year plus a 3% penalty. As time goes on, this won’t get any cheaper.
What if you're found non-compliant with GDPR?
Microsoft has released updates to ensure NAV 2015 and newer versions are compliant with the GDPR and Making Tax Digital but, if you’re on an older version, it’s up to you to remain compliant. If you are found to be non-compliant, this could blemish your reputation.

Upgrade from NAV to Business Central
Struggling with older NAV version? Upgrade now to Business Central with Mercurius IT for better and faster ERP operations.
See what our customers say
“Mercurius came in, had a look at all the requirements of the business, had a good understanding of not just what we wanted today but what our strategy was for the group going forward, and came up with several proposals looking at what was the best fit in terms of a system that could grow with the business as the business grew, and ultimately gave us advice and recommendations for the one that was the best fit for us. We can implement the solution across many different sites over the coming years. ”
Grundfos have been working with Mercurius on the development of an integrated Claims Management solution.
Based on Microsoft technologies it integrates with our CRM and ERP systems to substantially improve our claims management process. It also offers our customers a much-simplified approach to raising and completing a claim and enables them to both view and add claims online.
Not only did Mercurius beat our existing partner’s quote by a significant margin, they did it at a fixed price - removing our commercial risk.
In the end, they guided us carefully through the process and also implemented some great improvements to our business using the new features.
Frequently Asked Questions about upgrading ERP

My system is heavily customised, and I need to keep my customisations after upgrading
We recommend utilising Business Centrals Extension’s feature if customisations are very specific to your business and it cannot be replaced by standard functionality in the new version. The Extension feature takes the customised code away from the source code, which saves you time and money in the long run since upgrades will be straightforward.
An upgrade is too risky
All developments completed by Mercurius follow the Microsoft Sure Step Methodology and are piloted in a test environment before go-live, ensuring your upgrade goes smoothly.
An upgrade will be too daunting for users
Business Central does come with a new User Interface, but it has been designed to help users accelerate their productivity and navigate more easily throughout the application – especially compared to a legacy system that is years old. We involve end-users early in the project to understand their requirements and provide sufficient training so that, by go-live, they have already seen and tested the system.
I won't Benefit from upgrading
Business Central integrates with other Microsoft products, including Office 365, Dynamics 365, SharePoint, and the Microsoft Power Platform – along with in-built intelligent functionality. On top of this, it is compliant with new legislations such as GDPR and MTD.
