The Hidden Cost of Poor Inventory

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

Integrated 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.

Inventory Forecasting FAQ

Everything you need to know about forecasting inventory on Amazon.

· Written by the SellerMagnet Product Team

When a product goes out of stock, Amazon removes your listing from search results and ad campaigns pause automatically. Your BSR drops and competitors capture your Buy Box share. Recovery typically takes 2 to 4 weeks. SellerMagnet's inventory forecast predicts your stock out date so you can restock before this happens.
The IPI is Amazon's score (0 to 1,000) that measures how efficiently you manage FBA inventory. It considers excess inventory, sell through rate, stranded inventory, and in stock rate. A score below 400 can trigger storage limits. SellerMagnet helps you maintain a healthy IPI by preventing both stockouts (which hurt in stock rate) and overstock (which increases excess inventory).
Yes. SellerMagnet's Inventory Planner supports All Amazon marketplaces worldwide, including .com, .de, .co.uk, .fr, .it, .es, .co.jp, and more. You can view all marketplaces in a single table or filter by specific regions. The tool also supports Pan-European FBA (EFN) reporting mode, so you see consolidated stock levels across all European fulfillment centers.
SellerMagnet connects to Amazon's SP-API and syncs your catalog, stock levels, inbound shipments, and order history automatically. Initial setup takes less than 5 minutes with a secure one click authorization. After that, data refreshes multiple times per day so your forecasts always reflect current conditions, including recent sales spikes, returns, and inbound inventory updates.
SellerMagnet analyzes your average daily sales velocity over a configurable lookback period (7 to 365 days), factors in your current stock, inbound units, and reserved inventory, then calculates how many days of coverage you have left. The reorder quantity equals your target replenishment window (e.g. 30 days) multiplied by daily sales velocity, minus current available stock.
Yes. You can filter inventory data by fulfillment type: All, FBA Only, or Seller Fulfilled. Each product row shows its fulfillment channel alongside stock levels, daily sales velocity, days of coverage, and restock recommendations. This lets you manage FBA replenishment and merchant fulfilled orders from a single table without switching between Seller Central reports.
You can choose from seven lookback windows: 7, 14, 30, 60, 90, 180, or 365 days. Shorter periods react faster to recent trends (good for seasonal products), while longer periods smooth out volatility (better for evergreen catalog items).
Every product receives one of six status badges based on its days of coverage: Out of Stock (zero units), Critical (fewer than 7 days), Low Stock (fewer than 14 days), Healthy (above your target window), Overstocked (significantly above target), and No Sales (no recent sales activity). Each status has a recommended action.
Yes. The Inventory Planner supports one click export to CSV or Excel. The export includes all visible columns: product details, stock levels, sales velocity, days of coverage, expected stock out date, units to send, and status. You can use this to share restock plans with your prep center or supply chain team.
The Inventory Planner is part of the Analytics Dashboard and is available on all paid plans. A free tier with limited product count is also available for sellers who want to try the tool before upgrading. Every paid plan includes unlimited marketplaces, export functionality, and all six stock status badges. Check our pricing page for current plan details, limits, and free trial options.
Connect your Amazon account to SellerMagnet, set your target replenishment window, and the Inventory Forecast calculates your exact stock out date for every SKU. You receive color coded status badges and reorder quantities so you can ship inventory before running out.
Inventory demand forecasting uses historical sales velocity to project future stock needs. SellerMagnet's forecasting engine lets you choose lookback periods from 7 to 365 days, accounting for seasonal trends and sales spikes to calculate accurate reorder quantities.
