I am a home improvement consultant. Who knows how to get the customer list from the sales department?

I am the manager of a brand decoration company. Generally speaking, you need telephone information. You can't go to the sales office. You can try some advertising companies. They will have a supply of goods, and you can find another decoration company to be responsible for the procurement of the marketing department. Don't trust any first-hand information. There will be no first-hand information unless you leave the market for more than half a year. If you go to the sales office, you can talk to them and make a list. They are more sophisticated than you, but I advise you to go down and take more property relations. You can ask me if you don't understand anything.
