Looking for some help regarding the monitoring of Third Party Senders. We currently do not bank any and we're looking to onboard a rather large one in order to increase our footprint/expand our services/etc. Can anyone share what their onboarding process & monitoring techniques are for this sort of a customer?

I would additionally like to point out that this particular Sender is strictly limited to payroll processing for approximately 500 companies.

Any information that is provided would be more than helpful/appreciated!
