Ask anyone who owns a service business if they know how to provide good customer service and they will all say “yes.” They will offer to send the customer an email with an appointment that can be added to their calendar. They will contact the customer when the service technician is on their way or if they are running late. They will leave a note or work order indicating what service was performed. They might follow up after the service was performed to ensure the customer was happy with the service that was done. If the service is one that should be done periodically (pest control, air conditioner cleaning), they will contact the customer when it’s due and try to schedule it.
