The number one cause of stockouts is not demand spikes.
It is safety stock formulas that still assume 2019 lead times.
We have seen accounts carrying six hundred units of ASINs that sell eight per day. And thirty units of ASINs that sell forty per day. Both calculated from supplier promises, not actual ship dates.
The Inventory Guardian agent pulls real transit times from every shipment. Calculates actual velocity from every sale. And flags the SKUs heading for a cliff three weeks before you hit the red.
What is your current safety stock based on? Supplier quotes or actual data?
