Shipping, Receiving, and Inventory Clerks

Requisitioning, receiving, storing and issuing medical supplies while maintaining accountable inventory records transfers directly to supply and inventory work in healthcare facilities and distribution operations.

  • Requisition and store shipping materials and supplies to maintain inventory of stock.
  • Record shipment data, such as weight, charges, space availability, damages, or discrepancies, for reporting, accounting, or recordkeeping purposes.
Civilian tools and software (examples)
