Odoo is the world's easiest all-in-one management software. It includes hundreds of business apps:
CRM | e-Commerce | Accounting | Inventory | PoS | Project management | MRP | etc.
My odoo system has been hosted in the cloud. And I can access through the private IP address only. Recently, I can create a demo database but when I installed an app after some time odoo shows a blank page. It does not show any application nor any images or menu bar.
