Dynamic Industrial is a relatively young company, with an unsophisticated accounting system. Dynamic Industrial manufactures two products, X370A, and Z410B. Each of the products has multiple components and materials (identified by SKU number), but assembly is relatively quick leaving no work in process inventory at the end of the period. Invoices are only approved for payment if the full quantity of the SKU has been received.1.
