Engineers tend to overestimate how difficult machine learning is. That is exactly how a good data scientist would solve this problem. If (and only if) this initial solution is not sufficient then you can iterate on it (maybe we should also take into account monthly trends, maybe one category of products is overrepresented, ...).
