Don’t run out of stock with reordering rules
To make sure you never run out of stock, you can define Reordering Rules on products. Thanks to them, Odoo can help you replenish your stock automatically when it reaches set quantities or whenever a sales order is created.
Configure your storable product
Open or create a product with its Product Type set to Storable Product.
As you are purchasing this product from a vendor, go to the product’s Purchase tab and add a vendor by clicking on Add a line. You can add multiple vendors, but make sure to order them correctly, since reordering rules always use the first vendor in a list. You can add a price, but it isn’t necessary for the reordering rule to work. In addition, you can add a minimum quantity you must order to benefit from that price.
Next, make sure the correct route is selected under the Inventory tab of your product. If you created your product within the Purchase app, the Buy route is selected by default. If you are looking to dropship your product, select Dropship.
Set up your reordering rule
Open your product and click on the Reordering Rules button.
Once you are on the product’s reordering rules page, click on Create.
You can set a minimum quantity your stock should always have. Once set, if your stock goes below the minimum quantity, and if you selected the Buy route, a request for quotation is automatically generated to reach that minimum quantity, plus any additional quantity needed to fill in a sales order for example.
If you set a maximum quantity, every time the product has to be replenished, enough products are reordered to reach the maximum quantity.
If you want to order only the exact quantity needed to fill in a sales order for example, set both both the minimum and maximum quantity to zero. The quantity mentioned in the sales order is then used by the reordering rule.
You can also add a quantity multiple to only order products in batches of a certain quantity. Click on the optional columns drop-down menu, and select Multiple Quantity to show the column. Bear in mind that you might go over the maximum quantity you set if your rule includes a quantity multiple, as Odoo orders enough products to reach the maximum quantity and respect the set quantity multiple.
