So put it on the moment before you answer the phone. No matter what the situation, your cordial attitude will help. A little knowledge goes a long way. If you can educate your customers while you sell, you add value and encourage retention. Providing information as you sell, either combined with or separate from your hard-hitting sales messages can go a long way .
People love catching little bloopers, oversights and out and out mistakes.
While you may find it embarrassing to have a customer report an error, think of it as concern by a valued customer for your reputation. Put out the welcome mat. A new customer deserves a warm welcome. Whatever you do, though, let your new customer know how thrilled you are with his or her confidence in your product or service and move him or her along the way to that cross-sell or referral. Let your customers know how smart they are.
