Yes. Your unsubmitted bulk bond lodgements will be automatically saved when you exit the Web Service. You will be able to come back and continue where you left off.
Remember, it’s a legislative requirement to lodge a bond within 10 days of receiving payment from the bond contributors. The Bulk Bond Lodgement Web Service only stores unsubmitted bulk lodgements for 10 days. After this time, the bulk bond lodgement will be deleted.
