http://www.openpracticesolutions.com/web-based-pm-software/Open Practice Solutions was founded in 2005. They operate out of Stow, Ohio. It appears that
Open PM is one of their products.
Any title with the word Open in it would imply that it is open-source software, with the source-code made available to the public for a community effort at software development. I can't tell from the website if that is what is going on here. No demos available on the website; not even screen-shots. If I were searching for PM software and actually found their website in a search, I would pass it by in an instant. I'm not into contacting folks so they can
sell me on something. I want to examine it myself, at my own pace, to see if it meets my needs.
The software does not seem to have much of a track record, if any at all. Googling on
Open PM +
Medical Billing or
Practice Management gave me only one relevant link. From a marketing standpoint, using
PM in the title is probably not good. PM also returns hits on Property Management and Project Management. software.
