How do I calculate the reorder point?

Multiply average daily usage by lead time, then add safety stock. For example, 20 units/day over 7 days plus 0 safety gives a reorder point of 140 units.

Should I include safety stock?

If demand or lead time varies, yes. Safety stock absorbs the variation. If everything is very stable you can leave it at zero, but that is rare in practice.

How is this different from safety stock?

Safety stock is a buffer against uncertainty. The reorder point is the trigger level that includes lead-time demand plus that buffer.

How does Odoo handle the reorder point?

Through reordering rules: Odoo triggers a purchase or manufacturing order when stock drops below the minimum you set, accounting for vendor lead times.

When on-hand stock reaches this level, place the next order. Keep usage and lead time in the same time unit (days).

How This Calculator Works

The reorder point (ROP) is calculated as average daily usage times lead time, plus safety stock. The first part covers expected demand while the order is in transit; safety stock covers spikes and delays. When on-hand stock reaches this level, it is time to order. Keep usage and lead time in the same time unit.

How This Maps to Odoo Inventory

Odoo Inventory automates reordering through reordering rules: you set a minimum and maximum, and Odoo generates purchase or manufacturing orders when stock drops below the threshold. Vendor lead times and safety quantities plug right in. Octura configures those rules, routes, and lead times so replenishment runs without manual watching.

How this calculation is made

The Octura Reorder Point Calculator is calculated as (average daily usage × lead time in days) + safety stock. That is the on-hand quantity at which a replenishment order must be placed for stock to arrive before the shelf empties.
