Vertex Q series Vs Vertex O series



We are in process of switching our tax software from Vertex Q series to Vertex O series. Has anyone tried this and what are benefits of changing from Q series to O series ? We are using JDE enterprise one 9.1 and this is only implemented in US .
From what I understand is that Q series is certified by Oracle and O series is not . This means that customization if needed would be done by Vertex Consultants .
From administration stand point ,what would be the pain points as I saw that the O series uses a different server (web service) called by business functions via XML. What 's the performance look like comparatively to Q series.


Hello Nyam,

I would be interested to hear how your switch went if you are willing to share. We are on Q and considering changing.
