FBA stockouts and stranded inventory explained

An Amazon seller can run out of sellable stock while still owning inventory. Units may be in production, travelling to a warehouse, awaiting receipt or linked to an offer that is no longer active. The first useful action is to separate those situations.

Amazon describes stranded inventory as FBA stock that lacks an active offer. Its help page should be checked in the affected marketplace for the applicable correction options.¹ Ordering more units will not resolve that listing connection.

Build an inventory view by SKU

For each seller SKU and marketplace, record sellable stock, inbound units, relevant reserved quantities, unfulfillable stock and stranded inventory. Add confirmed purchase orders separately. Avoid counting a shipment both as inbound stock and as a supplier commitment.

Assign a next action to every exception. A stranded item needs the offer issue investigated. A delayed shipment needs shipment evidence and a realistic receiving estimate. An unfulfillable item requires the relevant disposition review. Use the current account options rather than assuming the same action fits every status.

Estimate when to reorder

A simple planning calculation is expected daily demand multiplied by total replenishment lead time, plus a safety allowance. Lead time should include production, inspection, transport and receiving assumptions, not only the supplier's promised dispatch date.

For illustration, demand of 8 units a day across a 45-day lead time requires 360 units. Adding a 90-unit buffer gives a 450-unit reorder point. This is a planning example, not an Amazon rule or a recommended buffer. Compare the trigger with your inventory position and confirmed supply, and adjust for seasonality and uncertainty.

A recent promotion may make average daily sales unsuitable for the next period. Document the period used, planned promotions and any changes to price or distribution. Review your forecast against actual demand so the buffer has a reason behind it.

Connect the plan to cash

Before placing a reorder, list the deposit, balance payment, freight payment and expected availability date. The timing matters even if the product has a positive margin. More inventory can reduce stockout risk while creating excess storage cost or leaving too little cash for other products.

Amazon's FBA information describes fulfilment services and fee categories, but actual charges need the relevant marketplace and product details.² Use the current fee tools and your charged transactions when assessing an order.

Hold a short weekly review

Review low-stock products, delayed inbound shipments, stranded items and slow-moving stock. Give each action a person and a review date. Keep an exception open until the account or physical evidence shows it is resolved. A message sent to a supplier is progress, not proof of receipt.
