What are the practical implications of exceeding Amazon's Inventory Performance Index (IPI) threshold?

Exceeding Amazon's Inventory Performance Index (IPI) threshold, which is typically set at a specific score, has several practical implications for sellers using Fulfillment by Amazon (FBA). The most significant implication is potential limitations on storage volume within Amazon's fulfillment centers. Sellers with IPI scores below the threshold may face reduced storage limits, preventing them from sending in as much inventory as they would like. This can lead to stockouts and lost sales opportunities. Additionally, sellers below the IPI threshold may be subject to overage fees if their inventory exceeds their allotted storage space. These fees can significantly impact profitability. To avoid these consequences, sellers must actively manage their inventory by reducing excess inventory, increasing sell-through rates, and resolving listing errors. Maintaining a healthy IPI score ensures optimal storage capacity and avoids costly overage fees, allowing sellers to effectively manage their FBA business.
