Ask the Customer if it is a Good Time to Call
Sometimes you might contact a customer or prospective one at a bad time. The customer may indeed be interested in talking with you, but just has other more pressing business to attend to at the time. Pursuing the contract at this particular time may only serve to irritate the customer. Instead of returning your call at a more opportune time, the customer may lose their patience and interest in talking with you.
Everyone, including your customers, is very busy these days at work. When contacting a customer, it is a good idea to ask if it is a good time for them to talk or not. The customer will appreciate your consideration for their time and hopefully respect yours as well.
Think of a situation when you tried to contact a customer at a time not convenient for them. What was the result?
How could this contact have been more productive if you had asked if it was a good time or not for the customer?
