How does MS Dynamics 365 work?

Hi Lilo, thank you for posting in the community. How big is your business? And what sector are you in? Your response may change my answer below..

Nevertheless, usually we recommend Microsoft Dynamics 365 Business Central as an affordable comprehensive ERP system - it combines Sales, Marketing, Finance Operations, Cash and Bank management and supply chain features all in one software package. 

In terms of how it works: standard configurations for most business processes are built in, and then you can customise them to suit your needs. All you need to get started is a license - but you can also try the product for free on a trial basis. 

You will probably find this website really useful:  https://www.microsoft.com/en-us/dynamics-365/products/business-central?msockid=3c4e3e4071486cdd07582bc070a86d0f.

Please feel free to contact me if you have any further questions, or if you would like to organise some training. I am happy to help.
