Last night at 8.08 pm ACC advised the following:

"Today's SendInvoice outage has now been resolved.

Any invoice submissions sent from 12.05pm on Wednesday 26 March until now should be resent, even though they show as successful submissions within your SendInvoice submission history.

Please let us know if you encounter any further difficulties.

We apologise for the inconvenience this has caused, particularly nearing month-end.

Ngā mihi
