OpenVPM vs NaVetor
NaVetor is an affordable cloud system from Patterson, with a soft tie to Patterson payments. OpenVPM keeps the affordability and keeps you independent.
NaVetor, owned by Patterson Veterinary, is an approachable cloud system for new and growing practices, with a low starting price and the option to use it free if you run payments through Patterson. It is closed-source and most useful inside the Patterson ecosystem. OpenVPM offers an affordable, modern alternative that does not tie your software to a particular payment processor or distributor.
Pricing for other systems is publicly reported by third parties, not official rate cards. We aim to be fair. If something here is out of date, tell us and we will fix it.
What about your data?
NaVetor offers report-level export, and the free-with-processing model creates a soft tie to Patterson payments. OpenVPM keeps a public schema and full export with no processor strings attached, so your software and your data stay independent.
