I'm doing elevator sales now, but I don't know how to do it well. How to get information? How to communicate with customers?

The main customer of elevator sales is the construction party (Party A), because elevators are a special industry, which is not within the scope of general contracting, and most of them are ordered by the construction party through separate bidding. Multi-channel access to information and online search; Build a big table; Construction and management departments; Even friends, relatives and classmates are channels for collecting information. But the size varies from person to person. Choose a good contact person, ordinary people don't work. We should talk about ways and means in life, and do it when it is time to do it, otherwise the success rate of life is almost zero. Moreover, the brand of elevator is very regional. Kone elevator is very popular in Tianjin, but not necessarily in Beijing. Have a good analysis.
