What is FBA?
Fulfillment by Amazon means sending inventory to Amazon fulfillment centers so Amazon can store stock and fulfill eligible orders. It does not remove the need to plan quantities, monitor receiving or understand why stock is unavailable.
FBA & Inventory Management
Plan around the stock that can actually sell
Inventory needs to be available at the right time and in the right quantity. AM Services connects FBA inventory states, inbound timing and replenishment decisions with sales, promotions and advertising priorities.

Available
Available inventory informs demand and advertising decisions.
Workflow overview
Inventory states explained
These are status categories, not a single sequence that every unit follows. Review the account’s current inventory report and the reason attached to the units.
Available
Stock Amazon reports as available for sale; review the offer and delivery context as well.
Inbound
Units moving through shipment preparation, transport or receiving. Inbound does not mean fully available at the destination.
Reserved
Units set aside for customer orders or fulfillment-center activity. Review the reservation reason rather than treating the total as one problem.
FC Processing
Units under additional fulfillment-center processing or checks. This may appear within reserved inventory reporting.
Unfulfillable
Units Amazon considers unsuitable for fulfillment in their current condition; the required action depends on the reason.
Stranded / unavailable
Stock without a buyable offer or with another availability issue. A catalog or offer correction may be needed even when units are physically present.
Why inventory affects growth
A stock interruption can break sales continuity, delay a launch and leave advertising without a suitable offer. Availability and delivery expectations also affect the customer’s buying decision. These dependencies can influence commercial momentum; there is no guaranteed ranking outcome from a stock change.
How much inventory should you send?
There is no quantity that is right for every product. Balance likely demand with replenishment speed, cash exposure and the risk of excess stock.
Existing products
Review sales velocity, seasonality, current FBA stock, inbound units, supplier and transit lead times, replenishment frequency and planned promotions.
New products
Estimate demand from the category, competing offers, price, launch plan and replenishment speed. Start with a controlled quantity, then adjust as real sales data arrives.
Replenishment planning
Estimate how long usable stock can cover expected demand, then compare that coverage with the full replenishment lead time. Include supplier preparation, transit and Amazon receiving uncertainty. A reorder point is account-specific, not a universal formula.
