Its pretty simple actually. Lets take an example of the ACH (Automated Clearing House) industry.

The hierarchy would look something like this:


  • For Acme ACH Processing - their upstream processor is Paymentech (JP Morgan Chase)
  • For Paymentech - their downstream aggregator (or Customer) is Acme ACH.
