Inventory planning begins with daily run rate, lead time and safety stock. A SKU selling 25 units per day with a 12-day replenishment cycle needs more than 300 units before buffer.

What sellers should know.
This page is written for ecommerce teams that need clear decisions, not surface-level definitions.
Marketplace inventory must consider event spikes, ad scaling, returns, warehouse transfers and fulfillment model. FBA, Smart Fulfilment and dark-store inventory all behave differently.
Quick commerce requires store-level cover, not just central warehouse stock. A city can show strong demand while specific stores keep losing sales due to low fill rate.
Dead-stock risk rises when slow-moving inventory is pushed into channels without demand, poor content or weak offers. Apex reviews stock by velocity and margin before promotions.
