About Our Product Warehousing and Fulfillment Service

Storing products is only one part of running a warehouse operation. Inventory has to be recorded when it arrives, kept organized and picked correctly when orders come in. River Plate handles these tasks at our Simi Valley facility, along with packing and preparing orders for shipment.

We work with businesses that ship directly to consumers, supply retail partners or distribute products in larger quantities. The work varies by business, so we start by discussing your products, order flow and storage needs. Our team can also handle kitting, assembly, labeling and other product preparation as part of the warehouse process.

For businesses that use River Plate for both warehousing and fulfillment, inventory storage and order processing take place within the same operation. That gives you one team to contact about stock arriving at the California 3PL warehouse and orders leaving it.
