Vendor Bills
The payment to the vendors for the purchase order will be up to date if the vendor bills are registered in the Odoo system. All the vendor bills operations in the platform are directly linked with the vendors. Odoo assists you to generate vendor bills either delivered quantity basis or ordered quantity basis. For setting up the default bill control policy for all the configuring products operations, first of all you should define it in the Settings window of the Odoo Purchase module. In the settings menu you can view the Bill Control option under the Invoicing tab. Here you have the Ordered quantities and Received quantities options. You can define the bill control either to be based on Ordered quantities or Recieved quantities.
With this option in Odoo you will get a chance for defining how the vendor bills will be controlled. With each of your purchase orders, you have the right to choose when the associated vendor bills need to be paid. This can be possible before receiving products or after receiving your products. You can create a vendor bill immediately when you confirm an order if you are selecting Ordered quantities. The quantities described in the purchase order are opted for generating the raft bill. In the case of Received quantities you are only able to create vendor bills when you received a few of the products that you ordered. So the draft bill can be generated based on the quantities you have received. In this case, you will receive an error message when you are trying to create vendor bills without receiving any products.
Control Policy
You can also view the Control Policy option under each and every product window in the platform. Odoo provides you the provision for control or modify a specific products control policy directly from the Products window. Under the Purchase tab of the products window, you can view the Control Policy option as depicted in the below image. Using this field, you can directly assign the bill control policy of the product and can be easily defined straight from the products window. This will be a great advantage to you to work with the order policies of the product being defined.
So we discussed the Vendor Bills and Bill Control policies of the Odoo Purchase module and now let us discuss the another exclusive option available in the platform - 3-way matching purchase receptions and bills.
