What the Inventory Hub Helps You Decide

The Inventory Hub is designed for sellers who need to avoid two expensive problems: stocking out while a product is ranking, and tying up too much cash in slow-moving inventory. Add your SKUs, current stock, daily sales velocity, supplier lead time, inbound shipping time, safety stock, unit cost, and FBA reimbursement notes to plan reorder timing and shipment quantities.

Reorder Methodology

The reorder calculation starts with daily unit velocity and lead time. It estimates the number of days until stockout, then compares that date against your production and shipping timeline. Safety stock is added as a buffer for demand spikes, supplier delays, or receiving delays at Amazon fulfillment centers. The result is a practical reorder point rather than a generic inventory rule.

This workflow pairs with the reorder point guide and the stockout prevention guide. Use those pages to understand the formulas, then use this tool to apply them to each SKU.

Shipping and Reimbursement Tracking

The hub also includes practical operating tabs for inbound shipping estimates and reimbursement case tracking. Shipping estimates help compare air, sea, and domestic freight assumptions at the SKU level. Reimbursement tracking gives you a simple record of lost, damaged, returned, or miscounted units so potential recovery does not get buried in Seller Central.

Privacy

SKU data is processed locally in your browser. SellerKit does not ask for Seller Central credentials and does not upload your inventory file to a server. Treat the output as a planning aid and confirm final shipment decisions against live Seller Central stock, inbound placement, and supplier production dates.
