Hi userdnamarine1028,
Thanks for reaching out to us with this question.
You are able to change your lodging frequency in QuickBooks Online to match what you have at the ATO.
To do this, go to the GST tab, select Settings, then select Tax Settings. You are able to change the frequency there.
Be sure to map out everything in QuickBooks, exactly as it reflects on the ATO's side, otherwise there might be errors when e-lodging.
Kristian.
