Personally, I think sweeping the building is more troublesome. The opening remarks can be made directly according to the five steps of marketing: say hello (enthusiastic and generous), introduce yourself (simple and direct), introduce the product (be sure to put the product in the customer's hands), close the deal (question, assume, action, praise), and then close the deal (pursue the victory) , more and more). Just walk in and tell the front desk: Hello, I am a credit card sales representative of Bank of Communications. I came to your company today to ask how many people in your company have not applied for credit cards. Remember to be confident and smile when you enter. Your smile and confidence make the other person feel safe, and they will buy your product (credit card) with confidence. However, I personally think it might be better to set up a stall on the street to give out gifts and sell credit cards. Everyone has the mentality of taking advantage, haha.
