Hey there, @np-design -
Welcome to the Community!
Definitely - you can click on the specific transaction and it will show you the fee paid on the very bottom of the details page.
Or you can see the fees paid on all transactions through the Reports for the timeframe you select.
Please let me know if you have any other questions.
That's not quite accurate @Kassi_. As the OP clearly mentioned, this issue is regarding partial payments on invoices. Square does not show this under Transactions in the dashboard.
On the Reports page it appears under Sales Summary > Payments with no detail or fee breakdown.
If you select Reports > Payment Methods mine is showing under "Card Keyed" (online invoice payment) and it does show the total Fees (far right column) but does not show a breakdown of the fees (% versus minimum $ charge). Hope this helps @np-design
