It depends on what industry you are in. The model of 58 cities is actually that sales are only responsible for sales, and the latter has nothing to do with sales. Only after-sales service department can contact you. If your consumption amount is large enough, there will naturally be after-sales service, and the consumption amount is not large. Maybe when your account is out of money, they will contact you after sale.

Because 58% of sales only have performance for the first time after signing the contract, the subsequent consumption is not their performance.
