Weeks-on-hand — for every SKU, at every fulfillment center
A single stockout number hides the truth: you can be flush at one FC and empty at another. SpyGlass shows weeks- and days-on-hand per SKU per location, so you fix coverage where it's actually short.
In short: SpyGlass computes weeks-on-hand and days-on-hand per SKU per fulfillment center against forecast demand, and alerts you when any location drops below target — so you rebalance before it becomes a stockout.
Coverage is a per-location problem
Network on-hand looks fine; then California runs dry while Kansas sits on six months of stock. SpyGlass breaks coverage down to SKU × FC so you see the real gaps — and get a transfer or replenishment suggestion to close them.
What you see
- Weeks-on-hand and days-on-hand per SKU, per FC, vs a target
- Red/amber alerts on any location trending to a stockout
- Rebalance and transfer suggestions across FCs and 3PLs
- Coverage that reflects inbound POs and production, not just today's shelf
Frequently asked questions
What is weeks-on-hand?
Weeks-on-hand (WoH) is current inventory divided by average weekly demand — roughly how many weeks of sales your stock covers before you run out. See our full explainer.
Can I see it per fulfillment center?
Yes — SpyGlass computes coverage per SKU per FC, not just a network total, so you catch a location that's about to stock out even when the network looks healthy.
Does it account for inbound stock?
Yes. Coverage reflects open POs and production landing at each location, so you don't over-order for stock that's already on the way.
