When the young entrepreneur compounds the problem by arriving late or not arriving at all, these customers rarely give them a second chance. Young people that are serious about their businesses make an extra effort to prove to their customers that they can be as punctual and as dependable as adult entrepreneurs. You should dress neatly when in contact with potential customers. A neatly dressed young entrepreneur sends the message that he cares about the way he looks and, hence, is likely to care about the quality of his work. You should be prompt when you show up to do the job or give customers an estimate of what it will cost to provide the service.
Nothing irritates customers more than waiting for someone to arrive.
You should go out of your way to be courteous to potential customers when soliciting their business. You should offer guarantees on every product you sell or any service you provide. A guarantee tells the potential customers that young entrepreneurs have enough confidence in their businesses to guarantee the quality of their products or services.
