Reordering rules

Reordering rules in Odoo Inventory automatically trigger purchase or manufacturing orders when a product’s stock falls below a set minimum, helping businesses avoid stockouts without tracking every product manually.

What reordering rules do

A reordering rule watches a product’s forecasted stock at a specific location. When it drops below the Minimum Quantity, Odoo generates a replenishment order to bring stock back up to the Maximum Quantity. The type of order depends on the route configured on the product: the Buy route creates a request for quotation (RFQ), and the Manufacture route creates a manufacturing order (MO).

Before you start

Before setting up a reordering rule, the product must be configured correctly:

1. On the product form, set the Product Type to Goods and make sure Track Inventory is enabled, so Odoo can monitor its stock levels.
2. On the Inventory tab, tick the Buy route to replenish by purchase, or the Manufacture route to replenish by production.
3. For the Buy route, add at least one vendor and price on the Purchase tab. For the Manufacture route, make sure a bill of materials exists for the product.

Setting up a reordering rule

To create a rule, go to Inventory > Operations > Replenishment, or open the Reordering Rules smart button from the product form, and click New. Fill in the following fields:

• Product and Location: the item and warehouse location the rule applies to.
• Min and Max: the minimum quantity that triggers replenishment, and the target quantity to reach.
• Multiple Quantity: rounds the replenishment quantity up to the nearest multiple of this value, without exceeding the maximum.
