I completely agree with you about paying for all the support no one never gets lol… That’s why I got openEMR as well. I absolutely love the billing portions of it. Needs some major tweaks but overall, it work. I never like paying for something I cannot own and can use at the same time which is why I told every company off I found what I needed.
Unfortunately, I cannot use it because I do not have a HIPPA compliant hosting server. Thought to hosting them myself! and then build a tiny sftp code in the clams portion of the app to submit my directly to claims to OA.
