My only experience with MPA3 is the implementation that Epoch uses on it's merchant side. I didn't like it, didn't seem very intuitive, and reports were hard to get the info I wanted, that is most likely just because I was used to nats and I don't enjoy learning curves. Since I used epoch as a biller in Nats there was no issue, I just got my info directly from nats and only checked the Epoch side periodically to review payouts.
