Definition
FBA (Fulfilment by Amazon) means you send inventory into Amazon’s fulfilment network; Amazon picks, packs, ships and handles many returns. FBA stock is not the same pool as your own warehouse or 3PL without deliberate transfers.
Worked example
You keep bulk stock in a UK 3PL and send weekly FBA inbounds sized to velocity and restock limits, instead of parking six months in Amazon storage.
Why it matters for replenishment
FBA changes lead times, fees, storage risk and restock constraints. Replenishment must model FBA as its own stock source.
How OmniRestock uses this
OmniRestock keeps FBA as a separate warehouse/stock source, forecasts demand, and plans transfers into FBA without double-counting supplier demand.
