The postage refill process has not yet completed, or there is an issue with the funding source.


If this message says "a refill is in progress", this means that a postage refill is currently taking place. Refills are normally completed within 60-90 seconds. After closing the error message, you should be able to successfully process a shipment.

If the message states that the account “does not have sufficient balance” and does not say “a refill is in progress”, this means that there is an issue with your funding account associated with this carrier.
