Setting up suppliers for ACH transmission to bank

OUr company is converting from writing paper checks to paying primarily by ACH.  I am working on the setup with JDE so that we can send the file directly to our bank.  Is there a document that has a checklist of all the items that need to be done so that I am not doing extra work or forgetting a step?  I am looking at the Setting up Bank accounts guide but still feel as if I am missing something.

Thanks,

Cyndi
