Yes! Fulfilment centres receive inventory, sort and shelf products in their respective bin, shelf, or pallet locations, and keep track of units on-hand. The goal of warehousing inventory in a fulfilment centre is to turn over stock quickly and ship orders out as efficiently as possible.
Most fulfilment centres will provide technology to help ecommerce businesses manage their inventory from afar, including inventory tracking tools that help you know when to proactively reorder product to prevent stockouts.
