This famous sentence came from the basic principle that the client is the priority in the sales process, one of the key expectations of a salesperson is the capability to fulfill the client’s demands.
Let’s get back to this final idea: Fulfill the client demands, because here is the key point to understand how toxic this sentence can be for a business.
Try to imagine the situation in which a client is requesting material for a product that we know is not going to work properly, just because is cheaper. Or that the client is complaining about a product damaged when they handle it outside the product indications. Or that a box is not strong enough to keep a product because the client did not measure the weight of the product correctly.
As companies, we are the experts in our fields, and is a part of our task to communicate effectively with our clients in order to guide them in a successful process even when this means letting them know that they are not right.
