Excuse me, what is the meaning of what is commonly known as cross-selling in the pharmaceutical industry?

Cross-selling is a common phenomenon in all walks of life.

I don't understand medicine. Let's talk about textiles.

For example, if you run a clothing brand, I will be your franchise dealer, and you will give me 4% off the retail price. My business scope is Linyi, Shandong.

One day, I had a message that a customer in Xuzhou, Jiangsu Province wanted to buy a batch of products. In order to expand business, I promised to give him a 5% discount, which was much more favorable than the price of the local franchised dealers, so I made it. But in this way, the dealer in Xuzhou lost his business, because if I hadn't intervened, it could have done this business at a 6% discount. In fact, his 6% discount price is still very advantageous in the local area. My business scope is beyond the established authority, which is called cross-selling.
