MCPNova MCP for Claude goes live in
The bridge that gives Claude context on your reconciled Amazon data.
The Amazon FBA inventory tracker built for restock decisions
Days of inventory, demand velocity, and pipeline per SKU across 21 marketplaces. Refreshed hourly.
Why inventory management breaks on Amazon
Seller Central gives you numbers, not clarity. Four problems quietly cost sellers thousands every month.
Stockouts kill momentum
Lost sales, BSR drops, wasted ad spend. Recovery takes weeks.
Excess inventory drains cash
Overstocking ties up cash and triggers long-term storage fees.
Blind restocking decisions
Without demand data, you're guessing when and how much to reorder.
Multi-marketplace chaos
21 marketplaces without a unified view means missed signals.
Every inventory metric, one table
One table. Demand velocity, stock position, runway, and pipeline, column by column.
Demand Velocity (Weighted Daily Units)
Weighted daily units with sparkline trends per ASIN. Recency bias surfaces momentum shifts as they happen, not after.
- Demand sparklines per SKU for instant trend reading
- Weighted calculation that prioritizes recent sales velocity
- Sortable columns to rank ASINs by demand
- Click-to-drill from parent to child ASIN level
Current Stock Position (FBA Available / Reserved / Total)
Three columns: what's sellable, what Amazon is holding, and your total. No guessing what's actually live to customers.
- FBA Available: units sellable to customers right now
- FBA Reserved: units held for orders, transfers, or processing
- FBA Total: complete picture of what's in Amazon's network
- Real-time breakdown at child ASIN level
Days of Inventory (DOI) with Color Coding
Color-coded DOI badges so risk reads at a glance. Formula: FBA Total ÷ Weighted Daily Units = days of runway.
- Auto-calculated per SKU, no spreadsheets needed
- Color-coded risk thresholds for immediate visual scan
- Sortable to surface danger SKUs first
- Formula: FBA Total ÷ Weighted Daily Units = days of runway
Pipeline & Future DOI (Inbound, Total Incl. Inbound, DOI Future)
Three pipeline columns factor in inbound stock. DOI Future recalculates runway including shipments in transit, so you plan restocks on the full picture.
- Inbound unit tracking for shipments in transit
- Total inventory including pipeline for complete visibility
- DOI Future projection factoring in what's coming
- Plan restocks with confidence using full-picture data

How sellers prevent stockouts with DOI + pipeline
The morning workflow: open the tracker, filter to ASINs at Risk, scan DOI for red, check Future DOI against inbound. Still red after pipeline? Restock today. Minutes, not hours.
Step 1 — Filter to risk
"ASINs at Risk" surfaces only the SKUs with low DOI relative to demand velocity.
Step 2 — Check the pipeline
Future DOI factors inbound shipments so you don't over-order on stock that's already in transit.
Step 3 — Decide and act
Anything still red after pipeline goes on today's restock list. Link straight to the shipment plan in Seller Central.
