Actual responsibilities of a sales clerk vary by company; however, common responsibilities include using a cash register, making change and cross-sellling products based on a customer's current purchase. Sales clerks tend to have several job duties within the organization.
In addition to the previously stated duties, some companies also give sales clerks other responsibilities. They might be required to set up advertising displays and arrange merchandise on counters and end caps so they look appealing. Some sales clerks have to receive inventory, price and tag inventory and provide friendly and knowledgeable customer service to customers in the store or on the phone.
