For many years, Pharmassist has used gross margin percentage ((Revenue - COGS)/Revenue) to evaluate the relative profitability of its market segments.

He meets with all the key managers and several of his operations and sales staff, and they agree that there are five key activities that drive other operating costs at Pharmassist: Each customer order consists of one or more line items. A line item represents a single product (such as Extra-Strength Tylenol Tablets). Each product line item is delivered in one or more separate cartons. Each store delivery entails the delivery of one or more cartons of products to a customer. Pharmassist's staff stacks cartons directly onto display shelves in customers' stores. Currently, there is no additional charge to the customer for shelf-stocking and not all customers use Pharmassist for this activity. Activity-based Cost Data Activity Level Pharmassist 2020 1.
