Reordering Rules
Learn how reordering rules maintain stock levels, how Odoo uses forecast quantities and min/max settings, and how replenishment differs from make to order.
Definition
In general ERP practice
A reordering rule is a stock-replenishment policy that defines when more of a product should be obtained and how much should be ordered. A common approach uses a minimum threshold and a target maximum stock level.
The rule needs a clear scope: which product, at which location, supplied by which process. Its usefulness depends on accurate stock records, realistic lead times and a replenishment target that reflects demand.
In Odoo
Odoo reordering rules compare forecast quantities with a minimum and replenish toward a maximum for a product and location. The replenishment route determines whether demand leads to purchasing, manufacturing or another configured supply process.
Rules can use automatic or manual triggers, and order multiples affect the suggested quantity. Forecast quantities account for expected incoming and outgoing movements, rather than simply copying today’s on-hand stock. A 0/0/1 rule can replenish demand without creating the same sales-order linkage as the MTO route.
Illustrative min/max rule
Minimum
Keep forecast stock above 10 units.
Maximum
Replenish toward 30 units.
Suggested quantity
If forecast stock is 8, replenish 22 units before applying any order multiple.
Reordering rules versus MTO
A stock-level policy replenishes a shared stock position. Replenishment on order responds to a specific customer demand. Choosing between them is a business decision about stock availability and demand traceability.
