Odoo is an open-source platform that combines business applications, including CRM, e-commerce, accounting, inventory, point of sale and project management, arranged in categories such as finance, sales, supply chain, HR and marketing. There is a free Community edition and an Enterprise edition that adds extra apps, infrastructure and professional services; many third-party apps exist as well. Odoo can be hosted on Odoo's own infrastructure (Odoo Online) or run on your own servers, and Odoo.sh is a platform for developing custom modules.
Odoo S.A. is based in Grand-Rosière, Belgium. According to its privacy policy, Odoo Online customer databases are hosted in the region closest to the customer; in Europe these are France and Belgium, but there are also locations in the United States, Canada and Asia, among others. The infrastructure is provided by Google, OVH and, outside the EU, Amazon Web Services. Organisations that self-host decide the location themselves.
