Hi All,

I was wondering if there was any system architecture document available for latest version i.e. 5.0.2 of OpenEMR. I have tried to look for myself but there is overwhelming number of documents and I got confused. Help in this regard would be really appreciated. Thanks

Hi @visolveemr

Thanks for your response.  
Yes, I did go through these links but couldn’t find my required document.  
Could you please help me in providing the Data Flow Diagram or Architecture document of Billing Module specifically? It’d be a great help. Thanks
