Make payment — Pay bill panel in Public Grid's energy app

Paying a bill in Public Grid’s customer app. The Make payment panel slides in over the account overview, where the outstanding balance is flagged in red, so the amount owed stays in view.

The panel reads top to bottom. First the saved Visa with its expiry and an Edit details link, then the choice of what to pay: the total amount due, only the past due balance (in red) or some other amount. The 3% card fee is tagged on the card itself and itemized again above the total, so nobody meets it for the first time on their statement.
