Compare →First and second by installed base in independent practices, and they split the map by state.
Compare →A market-leading platform against a system built for small independent practices. The size of the vendor is not the question here. Fit is.
Compare →Two systems aimed squarely at the one-to-ten-provider independent practice.
Compare →The budget end of the market: what you give up, and what you do not.

Compare →The specialty-native choice in eye care and dermatology, from two vendors that build nothing else.
Compare →Third and fourth overall — but they barely compete for the same practice.
Compare →Veradigm owns the sub-specialties. eClinicalWorks owns general practice. Which one you are decides the answer.
