IPI Score 350-399: Below Target — Improvement Plan

An IPI score between 350 and 399 means you are at risk of storage limitations, particularly heading into peak season (Q4) when Amazon tightens available storage for lower-scoring sellers. At this range, you likely have one or two significant problem areas dragging your score down rather than the across-the-board issues of sellers in the 300-349 range. Check your IPI dashboard for which factors are scoring lowest: usually either excess inventory or sell-through rate. For excess inventory: any ASIN where your current stock exceeds 90 days of supply is considered excess by Amazon's calculator. Set reorder points so you maintain 30-60 days of supply maximum for slower-moving products. For sell-through rate: this is your last 90 days of sales divided by your average 90-day inventory. Products with high static inventory and low sales drag this metric. Focus advertising spend on your lowest-velocity products to improve their sell-through ratio. Sellers in this range typically reach 400+ within 3-4 weeks of consistent inventory hygiene.
