By payment gateway fees, I mean the fees you paid to Stripe or similar for a transaction.
This isn't always possible with every gateway.
It'd be great to get some ideas and feedback into how this would look.
Would you want to see a whole report detailing fees, average order fees, % of overall revenue, change in it over time, etc.?
Or just would like to have a line item for total payment gateway fees paid in a period alongside the other order totals and take it into consideration for gross/net sales calculations?
