You refer potential customers and send us a list, we tell you what they bought and how much we owe you.

The hashed offline part probably refers to hashed email or other PII, so that we can exchange data without actually exchanging data.

Interesting, so like sort of like an affiliate program, but in like a bulk non-realtime way.

Is there any way from preventing under/over reporting of how many referrals were sent? Or is that just implicit in having the hashed identifier

Without hashes, there's some trust, statistics, and customer support involved. If the affiliate sender sees a lot of referral traffic from their end, and you don't report many visitors or conversions, often the affiliate providers will try and troubleshoot that to make sure you're seeing results that are in line with their other partners.
