========================== Invoice project milestones ========================== Milestone invoicing can be used for expensive or large-scale projects, with each milestone representing a clear sequence of work that will incrementally build up to the completion of the contract. This invoicing method is comfortable both for the company which is ensured to get a steady cash flow throughout the project lifetime and for the client who can monitor the project's progress and pay in several installments. Create milestone products ========================= In Odoo, each milestone of your project is considered as a product. To configure products to work this way, go to any product form. You have to set the product type as *Service* under general information and select *Milestones* in the sales tab. .. image:: media/milestone01.png :align: center Invoice milestones ================== From the sales order, you can manually edit the quantity delivered as you complete a milestone. .. image:: media/milestone02.png :align: center You can then invoice that first milestone.
