Frequently Asked Questions
What is a reorder point?
Reorder point = (Average daily sales × Lead time in days) + Safety stock. When your inventory hits this number, place your next order immediately.
How much safety stock should I hold?
A common rule is 15–30 days of sales as safety stock. Higher-velocity products or those with unreliable suppliers need more buffer.
How do I calculate how many units to order?
Order quantity = Daily sales × (Review period + Lead time) + Safety stock − Current inventory. This ensures you don't over- or under-order.
