Hello there,

Just before to pay an invoice, we have this button « Payer » in white color :

So we click the button « Payer » to pay te invoice. All works great. 

But after the payment, we have the button « Payer » in red color. And we can pay AGAIN...

In our last installation of Odoo, on an other server, it seems to me that we could not pay two times. The button was red Before the payment. Not after...

An idea to resolve it?

Thanks
