Quick Reference & Frequently Asked Questions
Why does my simple 'Average Daily Sales × Lead Time' formula keep causing stockouts?
Because averages ignore variance. If you sell 30 units/day and your factory takes 35 days, ordering at 1,050 units gives you only a 50% chance of staying in stock. Any week where sales jump to 38/day or customs holds your container for 6 extra days causes an immediate stockout. Our calculator factors both daily sales volatility and supplier delay variance.
How does ReorderGuard compare the cost of holding safety stock vs. running out of stock?
We compare the monthly working capital and 3PL bin storage cost of your safety stock buffer against the lost contribution margin of a stockout—plus the ad spend required to regain organic search velocity and BSR rank once inventory arrives.
Can I set different service levels for Hero A-tier SKUs versus slow C-tier sizes?
Yes. Carrying a 98% service level across all 200 SKUs wastes cash on slow colors and sizes. Our ABC matrix lets you lock a 98% buffer on your top 15% revenue SKUs while trimming slow-moving variants to 88%.
When does it make financial sense to pay for an emergency air-freight split shipment?
If your sea container is delayed by 12 days on a SKU earning $22 net contribution per unit at 30 units/day, a 12-day stockout costs $7,920 in lost profit. Air-shipping a 360-unit bridge batch at an extra $4.50/unit costs $1,620—saving $6,300 in net profit.
