+The Odoo *Repair* app allows you to manage a complete after sales
+process but also to simply repair products you have manufactured, if
+they present a defect.
+
+Create a Repair Order

+Manage a repair
+---------------
+
+When a customer sends you a product for repair, create a new *Repair
+Order*. Fill it in with all the information you may need such as the
+product, the customer, if it has to be invoiced after or before the
+repair, the parts you might need, etc.

+
+Once everything is done, you can then send the repair quotation to your
+customer. If it is approved, you can confirm the repair. You will then
+be able to start & end the repair when it is completed.
