Documents open in place, never navigating away

Every billing document used to navigate the customer off their dashboard, and a buyer who tapped an invoice to check one figure had to find their own way back. Invoices, agreements and change orders open over the dashboard instead. Backdrop click and Escape close them, and the page returns to exactly the scroll position it was at.

The invoice and the agreement each know when they are being shown inside the dashboard, and drop the back button and outer page furniture that would otherwise strand a customer inside a frame. Print stays, because the person reading their own agreement is exactly the person who wants a copy of it.

Hosted checkout refuses to load inside a frame, so the Pay button hands the customer a fresh tab and leaves the dashboard where it is. Returning to the dashboard tab re-reads the invoice, so the status and the remaining balance update in place rather than showing a bill they have just settled.

The same invoice renders standalone at its own address, inside the dashboard, and on paper, from one implementation. Two implementations means the printed copy and the on-screen copy disagree eventually, and the customer finds the difference before you do.
