Our system will retry the charge at these intervals:

If you would like to manually reprocess a charge yourself you can do so by visiting your most recent invoice in your account by selecting your Organisation name in the upper left -> Usage & Billing -> Receipts, where you will find a 'Pay Now' button on the outstanding invoice.

Once the charge successfully goes through, the banner will be gone.
