What the client actually sees
A public page, no login, that names who is requesting payment, the amount and asset due, the due date, the itemised reason for the charge, and the payment instructions: asset, network, receiving address, a copy button and a QR code.
Because it is a page rather than a message, it forwards cleanly to whoever releases funds — which in most organisations is not the person you have been talking to. If they need a file instead, the PDF carries the same content line for line.
