Many pure players or companies investing in webportals to expand their ecosystem have built their backoffice directly into their website. Such technology choice has limitations when expanding operations. In this workshop, learn from several OpenERP projects conducted by Audaxis where OpenERP (Odoo) sits as the NEW backoffice of web platforms : from collaborative tasks management in a caritative association, to Magento integration with OpenERP at a mail-order selling player ; from centralized back office at a multi-channel SMB operating in telco, to multi-country backoffice at a pure player delivering HR services... Different situations but same challenge : Which architecture is best? How to optimize integration? How to set up a sustainable solution?
