First off, this post is mostly stemming from frustration. So, if you’re expecting some sort of magic bullet to handle cumulative graduated pricing, I can’t offer you much. What I can offer you is a list of options, how they work, and why they may not fully satisfy the requirement. It seems simple: You want to offer your customers gradually reduced pricing — or gradually increased discounts — as they purchase throughout the year across multiple sales orders. Though seemingly simple, the solution is not.
