Invoice amount versus due amount

[Frankc]

Original invoice amount is $100

Payment of $50 applied

But the invoice amount still stay $100 on notices, admin and client area etc even while the amount due is now $50 and correct in all calculations.

While not a problem by itself it cause unnecessry support calls and misunderstandings when the invoice is still for $100 and not $50

Even if the PDF invoice can't be changed, surely the notices and outstanding invoices can show the DUE AMOUNT for that invoice instead than original invoice amount?
