Hello there, 

When you pay all the total amount of a supplier invoice, is the « pay » button still red on the top left of the invoice?

When I pay all the total amount of the invoice, the button stay red. If I click again on it, I can even make a new payment, even if invoice is entirely payed.

So, each time I pay an invoice, just after the payment, I use the breadcrumb to come back to the listing of all invoices.

And you?
