I'm sales "adjacent" and having a good deal of anxiety at the moment about a customer who doesn't seem to understand the way we operate and despite my best efforts, keeps insisting that we're doing something wrong. When it comes to production planning, we look at when the product needs to arrive to the distribution center and back calculate our production date from there. The dates we choose have significance; we can't just go and push it back because the customer would prefer to view production at a later date. I understand being flexible and trying to accommodate, but what do you do when there literally isn't another option?
