How to Fix IPI Score Drops, Pricing Errors, and Inventory Problems on Amazon

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

  1. Visit Manage Inventory → Suppressed in Seller Central.
  2. Compare “Your Price” to “Reference Price” data.
  3. Adjust pricing to align with Amazon’s thresholds.
  4. Use a rule-based pricing strategy to prevent auto-suppressions.
  5. 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.

5. Improving IPI Score Fast

  • Keep stranded inventory <1%
  • Maintain a sell-through rate >2.0
