1. What Is the IPI Score and Why It Matters
The Inventory Performance Index (IPI) determines how much FBA storage you can use. A low score means limited inbound shipments and higher storage fees.
Amazon evaluates:
- Excess inventory percentage
- Sell-through rate
- Stranded inventory percentage
- In-stock rate of key ASINs
Falling below ~400 can trigger storage caps and penalties — making proactive inventory management essential.
2. Common Reasons IPI Scores Drop
- Stranded inventory tied to inactive listings
- Excess or aging stock in FBA
- Suppressed listings from pricing mismatches
- Poor advertising or low sell-through
When Amazon’s “Fair Pricing” algorithm flags an item, it can deactivate it instantly, even if you’re below MSRP — disrupting both sales and IPI metrics.
3. Fixing Pricing Errors
- Visit Manage Inventory → Suppressed in Seller Central.
- Compare “Your Price” to “Reference Price” data.
- Adjust pricing to align with Amazon’s thresholds.
- Use a rule-based pricing strategy to prevent auto-suppressions.
- Reactivate listings manually once corrections are made.
4. Solving Inventory Problems
Stranded Inventory:
- Relink listings to correct ASINs.
- Delete old SKUs.
- Enable automatic removals for unfulfillable units.
Excess Inventory:
- Use multi-unit bundles or limited-time promos.
- Run PPC campaigns to improve velocity.
- Consider FBA Liquidations or Outlet Deals.
Stockouts:
- Use rolling forecasts to maintain in-stock rates.
- Balance FBA with FBM or 3PL for continuity.
