14. Closing Ability
To be clear, this has nothing to do with "closing sales" or other related terms.
Being able to close with a customer means being able to end the conversation with confirmed satisfaction (or as close to it as you can achieve) and with the customer feeling that everything has been taken care of (or will be).
Getting booted after a customer service call or before all of their problems have been addressed is the last thing that customers want, so be sure to take the time to confirm with customers that each and every issue they had on deck has been entirely resolved.
Your willingness to do this shows the customer 3 very important things:
That you care about getting it right
That you're willing to keep going until you get it right
That the customer is the one who determines what "right" is.
