Two systems aimed squarely at the one-to-ten-provider independent practice.
These two do not divide by size of vendor. They divide by size of practice. Both start at 1 (solo), so the split is at the top end: Tebra serves up to 6–15, AdvancedMD up to 16–50.
The registry puts Tebra (Kareo) at 0.3% and AdvancedMD at 0.4%. This measures the EMR identified by the Direct-messaging endpoint a practice registered with the federal NPPES registry. Vendors that sell mainly to small independent practices are systematically under-represented, because small practices are the least likely to have registered an endpoint at all. Read it as a floor, not as installed base. Both of these sell mainly to small independent practices, so those figures understate both of them — and there is no way to know by how much. They are not a ranking. Compare them on fit instead.
Everything above is what we can say about these two in general. What we cannot tell you from a page is what either costs at your provider count, in your specialty. Tell us and we will get you quotes from the vendors that actually fit — free, and we never charge practices.
Share figures are EMR Match Research analysis of the CMS NPPES Direct-endpoint data, July 2026 dissemination (n=37,310 identified providers) — the same source as our open data page, so the two can never disagree.
