When you do a photography job pro bono, are you doing anything wrong by not charging? No! It’s the same with shadchanus.
That’s a bad analogy as there is no halachic requirement to pay for a photography job. According to Chein, it seems that there is a mandatory fee dictated by halacha. Since I did not want to charge that, I was wrong and sinned.
Besides, Chein was referring to what must be paid, and you’re talking about what must be charged.
Well, if I refuse payment, then it’s a violation of “lifnei iver” since I’m preventing them from paying the halachically mandated amount.
