I use Zoomit and pay my invoices on time. But Zoomit is telling me that I have outstanding invoices : Zoomit Support

This can happen in two exceptional circumstances:

A problem happened while processing the payment status. If you can find the payment in your banks statements, you can change the payment status manually into Paid elsewhere.
A sender you didn’t accept yet in Zoomit proposes you a document to pay. If you did the payment outside Zoomit, you can ignore this message. You are advised to accept all senders available I Zoomit to avoid this issue.
