What Does Poor Inventory Planning Really Cost You?
Stockouts Kill Momentum
A single stockout tanks your BSR, pauses your PPC campaigns, and hands your Buy Box to competitors. Recovery takes weeks, not days.
Before
~$3,200/mo
lost revenue per stockout event (SellerMagnet aggregate data)
After
Zero stockouts
with predictive alerts
Overstock Drains Capital
Excess inventory ties up cash, triggers long term storage fees, and erodes margins. Every unit sitting idle is capital you cannot reinvest.
Before
5–15%
margin erosion from overstock (SellerMagnet aggregate data)
After
Right sized stock
with demand forecasting

PartialIntegrated with Analytics Dashboard
Inventory Forecast isn't a standalone tool. It's part of SellerMagnet's comprehensive Analytics Dashboard. See your stock projections alongside real-time profits, sales analytics, and cost breakdowns.
Through the Profit & Inventory Dashboard, you can see at a glance how many units remain for each SKU across every Amazon marketplace (.com, .de, .it, .fr, .co.uk, .es) and the daily sales velocity. The Amazon Alerts module sends instant notifications when a product drops below a preset threshold (e.g., 20% of initial stock), alerting you before a potential stock-out.
