Value is in the eye of the customer and a smart sales person would ask a series of loaded questions to learn as early as possible in the sales call exactly what the customer thinks. Service - A second cup of coffee without asking the waitress. A sales person stopping by to ask if there are problems or questions. Insuring the purchase order sails through the company bureaucracy so the customer gets the discount, the number of ordered items, the correct item, etc. Action - Separate from service.
Service is the result of action.
Too many of today's business people promise the moon but only deliver a tar pit. How many times have you been told that the whatchamacallit you just bought is the best, most long lasting whatchamacallit on the market today. Three days after installation, you are making a service call. Six days after delivery you are making a service call. Etc., etc., etc. 5.
