Wow! At first I thought you were a big fan of the NACHA rules! How disappointing to find that wasn't the case.
I think you will want to be careful about giving your business customers a "Reader's Digest" version of the the NACHA rules. They can be somewhat technical and complicated and by condensing their obligations and rights you may overlook something important. I would recommend either providing an actual copy of the rules or require that they obtain them on their own through your agreement with them.
The NACHA rules are available through the internet but only if you purchase the hard copy version first.
