What are the risks of not upgrading your ERP?

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.

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.
