A stockout doesn't just cost you today's sales. It costs you the ranking, the ad momentum, and the subscribers you spent months building.
One stockout, six places it hurts. Most of the damage outlasts the outage.
Listing drops out of search within days. BSR collapses. Recovery takes weeks of elevated ad spend just to rebuild velocity.
Subscribe & Save subscribers get paused or transferred to competitors. Recurring revenue you spent months building doesn't come back on its own.
Active campaigns keep spending against a listing with no inventory. Budget burns on clicks that can't convert into orders.
FBA capacity caps and ASIN-level restock limits mean you can't rush-ship your way out. Amazon won't accept the inventory.
Overstock the other direction and you pay monthly storage, aged-inventory surcharges after 180 days, and tie up cash that should be funding growth.
A two-week stockout can take two months of aggressive ad spend to recover from. The cost isn't the outage. It's the climb back.
Three formulas determine whether you stay in stock. Most brands learn them the hard way — after the first stockout, not before. We treat them as the operating layer of every account we run.
(Average daily sales × lead time in days) + safety stock. Sell 10 units a day with a 45-day lead time and 15 days of safety stock? Your reorder point is 600 units. Not when Amazon sends a low-inventory alert — before that.
Units in FBA divided by average daily sales. 200 units selling at 10/day means 20 days of supply. Below 30 on a core SKU is a red flag. Below 14 is an emergency.
Units sold in the last 90 days divided by average units stored. Amazon uses this to set your IPI score and storage capacity limits. Below 2.0 is a problem. Below 1.0 means you're paying to warehouse product that isn't moving.
We pull historical sales data, ad-driven velocity, seasonal patterns, and your promotional calendar to build a demand model for every SKU. Not a spreadsheet guess. A forecast that accounts for the variables that actually move your numbers.
We calculate SKU-level reorder triggers from your real lead times, supplier reliability, and demand variability. We factor in Amazon's capacity limits and ASIN-level restock caps so the plan reflects what Amazon will actually accept, not just what you want to send.
Inventory and advertising have to talk to each other. We align ad spend ramps, coupon schedules, and promotional events with your inventory position so you're never driving demand you can't fulfill. When inventory is tight, we throttle spend. When a replenishment lands, we scale it back up.
Demand changes. Suppliers slip. Amazon adjusts capacity allocations. We track days of supply, sell-through rate, and IPI score across your catalog and flag reorder windows before they close, not after.
