@JKingsnorth I think that https://lab.civicrm.org/extensions/stripechargeamount does this? If you also have a use-case it might be good to get it into the standard stripe extension but we should follow the same pattern (ie. customfield names etc.) as that extension.

@mattwire Stripechargeamount adds the charge_amount and charge_currency, but not the payout fee and payout net.

I think the custom field definitions here have just been copy-pasted from that extension, so they do follow the same format.

I really put this MR up to trigger some discussions about the best way to proceed. But my feeling is the more data we can hold about these transactions in CiviCRM, the easier it will be to reconcile and report.

To review after 6.11 release
