Odoo is an opensource ERP and eCommerce platform to manage all your daily business operations. The system is modular : it means that you can combine different apps together to create a fully integrated system: your online shop will be natively connected with inventory management, accounting, marketing applications, etc. You don't need complex and costly integrations anymore. Also, the Odoo interface is designed to be easy-to-use. You can create a website easily by using a simple drag&drop editor. Finally, being opensource allows developers to customize the system and create custom-made solutions.
