Dynamics NAV was Microsoft’s previous ERP solution for small to medium-sized companies. The software allowed you to automate business processes within your organization. Today this software is included in an application within Dynamics 365: Dynamics 365 Business Central.
Dynamics 365 includes all the possibilities of Dynamics NAV, but offers many more possibilities. The new business platform combines ERP and financial software with Dynamics CRM, workflow tools (to break down the walls between ERP and CRM solutions) and a tool for developing your own mobile applications with very simple code. All of this can be found on a single cloud platform.
For companies that are not ready to switch to the cloud, Microsoft still offers an on-premises version: Dynamics NAV 2018. However, you will not have access to the Business Application Platform in this case. Without the cloud, you will be unable to integrate the data from these tools seamlessly, which would result in fewer insights into your business processes.
