My story:

Never paid me for a ref.

My story: they never paid me nuthin'.
Then again, they owed me zero so it's all good. :D

Use ccbill.

Pardon late reply. Let me break it down here:

"- detailed member information on each transaction - member & transaction ID (for identification & keeping track of lifetime value in our own system), exact time (hour:minutes:seconds), full transaction history (the time of the first join and each rebill), country, biller, package/subscription type"

Answer: Via admin, open "edit members" and view all transactions under the table "Transactions History"
In the latest version of MPA3 we save timestamp for all transactions, and you can easily extract date, hours, minutes, seconds. We keep country and ALL transaction history of the member with the transaction type. All of this is for ADMIN of the program. For Affiliates we show sales, clicks, etc.

"- nested stats breakdowns - eg. I breakdown by site first, but then I want to break down only that single site by campaign"

Answer: Yes, MPA3 does that.

"- affiliate S2S postbacks on transactions"

Answer: We do miss that in the general version of MPA3. Some clients have added it as a custom solution.

"- add manual bonus to affiliates - when some affiliate program had some issue, they were unable to add the extra money to the MPA3 affiliate account (NATS has this option, called manual invoice)"

Answer: Yes, this is in MPA3. Admin can decide to use it, or not.

"- breakdown by continent/country - showed Unknown for all clicks"

Answer: This option can be turned on/off by sponsor. I would request it, if being an affiliate. Of if sponsor, just turn it on.

"- payment history - no payouts shown there, NATS also shows unstored/carried over sum"

Answer: Not sure exactly what you mean with "unstored/carried - MPA3 does show already generated payouts to the affiliates.

:2 cents::thumbsup

As an affiliate this info is needed too - to properly track lifetime value of each individual join sent. It is displayed for affiliates in NATS.
You are right. I just didnt realize it was a hover menu, I was looking for a button next to the row. :-)

I meant that it should also show how much money is held by the program, the "ungenerated"/unpaid amount. ;)
Something like
Unpaid amount: $99
Then you could expand it to get the details, eg.:
2017-07-01 - 2017-07-31 $43 under the minimum payout, carried over
2017-08-01 - 2017-08-31 $56 under the minimum payout, carried over

Regarding the rest, thanks for the info!

It seems like a lot of stuff is there, it's just the program owners not knowing / not using it properly. :(

What are you talking about? :)
Maybe things like this? --> https://gfy.com/fucking-around-and-pr...-question.html

it sucks for me on tier 5

One more catch: once you reached Tier 5 you will never get Tier 4 back,
Monthly rate could not be decreased depending on current sales...

Yes, that is correct - Unfortunately we cannot force program owners to use all the bells and whistles that are in MPA3. Some do, some don't.
