So I was thinking about sending a reminder about this check 21 law to my customers this month with the bills, reminding them of my returned check policy, etc. Personally, I don't wanna charge those fees, I just wanna get paid on time, and I don't mind working with customers to avoid those fees. I started wondering about policies on post dated checks, allowing customers to post date them to avoid fees, etc, but get the checks sent in on time. But I don't want to open that can of worms and start problems there. Anyone have thoughts?
