Dynamic inventory refers to inventory that moves very quickly and is influenced by multiple factors, making it difficult to manage. For e-commerce traders, inventory is crucial, as being out of stock can reduce customer confidence and future sales. Managing dynamic inventory effectively requires technology to synchronize inventory levels across all supply and sales points in real-time. An ideal system will automatically update inventory levels whenever a sale is made and allow suppliers to view stock and replenish automatically. Drop ship models pose even more challenges, requiring hourly or daily inventory updates from suppliers to ensure accurate stock information.
