Inventory Optimization
Holding the right amount of each product, no more and no less.
Definition
Inventory optimization is the practice of holding the right amount of each product, enough to meet demand at a target service level without tying up excess cash or warehouse space. It balances three competing pressures: avoiding stockouts, minimizing holding cost, and keeping order quantities efficient.
Why inventory optimization matters for FBA sellers
Your capital and your FBA storage space are both finite, and Amazon literally scores how well you use them through your IPI. Optimization is the difference between a catalog that funds its own growth and one that is cash-starved with money frozen in slow movers and surcharges eating the margin on the rest.
How inventory optimization works in practice
It runs on a few levers working together: a per-SKU demand forecast, safety stock sized to a target service level, a reorder point and order quantity that respect the ordering-versus-holding-cost trade-off, and disciplined removal of dead stock. For one SKU it gets concrete fast: a product selling 30 units a day with a 60-day lead time should trigger a reorder around 1,800 units (its lead-time demand) plus a safety buffer, not whenever it happens to look low. Blanket weeks-of-cover rules across the whole catalog are exactly what this replaces.
How inventory optimization connects to your restock decisions
Optimization is not a one-time cleanup project, it is the ongoing restock decision done well: per SKU, on real velocity and lead time, rather than a flat weeks-of-cover rule applied to everything. Every reorder is a chance to move a SKU closer to its right level.
