OpenERP is giving you a control over such situation where you can have everything in your hand to view and control over your margins.
OpenERP 7.0 made it very simple and easy to manage the costing / margin for projects through contract, it also supply automatic monthly invoicing to customer but that I will show you in future post. Here i would like to show you to manage the cost center using contract.
