Setting Up Min/Max Reorder Rules for Automatic Replenishment in Odoo

Min/Max Reorder Rules in Odoo Inventory#

Reorder rules tell Odoo when to automatically trigger replenishment - when stock drops below the minimum, Odoo creates a purchase order or manufacturing order to restore stock to the maximum level.

Creating a Reorder Rule#

Inventory → Operations → Replenishment → New:

How Replenishment Triggers#

Odoo checks reorder rules through the scheduler (run automatically or manually via Inventory → Operations → Replenishment → Run Scheduler):

1. Checks forecasted stock at the replenishment location
2. If Forecasted Stock < Min Quantity → creates a replenishment
3. Order quantity = Max − Current Forecasted Stock (rounded up to Multiple Quantity)

Immediate vs. Scheduled Replenishment#

Trigger modes:

• Fixed: always maintain min/max levels
• Lead Time: schedule the order to arrive exactly when stock will hit zero (based on demand)

Use Fixed mode for safety stock items; Lead Time mode for demand-driven replenishment.

Considering Lead Time in Reorder Points#

To avoid stockouts, set the minimum quantity to cover demand during the lead time:

• Daily demand: 5 units/day
• Vendor lead time: 7 days
• Safety stock: 3 days of demand (15 units buffer)
• Minimum = (5 × 7) + 15 = 50 units

When stock drops to 50 units, a PO is triggered. Goods arrive in 7 days when stock will be at ~15 units (the safety stock).

Seasonal Adjustments#

Adjust min/max seasonally:

• Pre-peak season: raise the minimum to build buffer stock
• Post-peak: lower the minimum to reduce carrying costs
• Edit the reorder rule directly or use an automated action on a schedule

Reporting on Reorder Rules#

Inventory → Operations → Replenishment:

• View all active reorder rules and their current status
• Filter by products below minimum → these need immediate attention
• "To Reorder" column shows which products the scheduler would reorder today

Exception Alerts#

Inventory → Configuration → Settings → enable replenishment notifications:

• Alert when a product is below minimum but no rule exists → prompts creation of a rule
• Alert when a vendor has no lead time defined → prevents optimistic scheduling
