Several problems about collecting money on credit

This should be no problem. For new customers, you can hang some related signs in the store that say no credit or something. For new customers, this can be said bluntly, such as "sorry, our capital flows faster here." Originally, it was a maintenance industry with low profit and needed money to buy new maintenance equipment. Please don't charge. " Most new customers can accept it, and it will not have much impact on your passenger flow. As for the old customers, I hope you can accept this. Old customers are not always the kind of people who love credit, but you are already familiar with them. So when you want money, you can say it directly, without hurting your feelings, and you can give many reasons for asking for money, such as "What is urgently needed in the store now, but the money on hand is not enough". One more thing, if an old customer has credit, you can write it down in person and in a notebook to remind him to pay next time. Give it to me at any time ",inadvertently reminded them.
