Benefits for Outbound interfaces?

I’ve been thinking about running outbound through AIF.. But, I’m trying to figure out what is the benefit AIF provides for those.

I can certainly see how inbound interfaces greatly benefit especially when we have multiple sources of information all doing the same thing (Creating A/P docs for instance)… We have many inbound scenarios in production right now.

But what about outbounds? Typically, most companies only send 1 interface out to a 3rd party so I don't see efficiencies gained in common mappings.

Thanks,

Robert.
