The Challenge Inventory lives in multiple systems that don't agree. The ERP shows one quantity, the WMS another, the 3PL a third, and each marketplace its own snapshot. Teams pad with safety stock to compensate, which ties up cash and still doesn't prevent overselling when a spike hits one channel before the others update. The APIWORX Approach APIWORX maintains a single reconciled availability picture. Every system reads from the same source, updates propagate in real time or near-real time, and allocation rules prevent overselling. FBA inventory is modeled the way Amazon reports it. 3PL updates flow into the ERP. Marketplaces see the same availability as your warehouse — without buffers. Capabilities ## Inventory Synchronization Features Everything you need for a successful implementation ### Multi-Warehouse Aggregation Aggregate inventory across ERP, WMS, 3PLs, and FBA into one reconciled availability number.
