OpenVPMS is structured as a not-for-profit organisation whose members are comprised of;

1. Users of its products (eg. Veterinarians using the Open VPMS web application to manage their practices).
2. Developers utilising the open source code to create other products or add to the existing web application.
3. Interested parties such as associated industry (e.g. Veterinary pharmaceutical companies, laboratories, microchip registries and wholesalers).

Open VPMS is run by a board of Directors that manage the business from day to day. The Directors are either involved in or have an interest in the veterinary profession and contribute a mixture of vision, expertise, funds and industry knowledge to the overall goals of the Organisation.

There are no shareholders, as all profits can only be used to advance the cause of the organisation and it's members.
