Sales technicians work with customers to find the products or services that best meet their needs and may deliver or install the necessary equipment on-site. As a sales technician, you ensure your customers receive the product or service they purchased and troubleshoot any issues they may have with the equipment. Specific job duties vary, depending on the company and industry. For example, an HVAC sales technician may be responsible for selling a new air conditioning system and also installs the system in the customer’s home. Sales technicians in retail operations may collaborate with the marketing department on marketing campaigns and train employees on product features and uses. There are no formal education requirements to become a sales technician, though many employers prefer candidates with industry sales experience.
