Thanks for chiming in on this thread, A2Z Computing. I'll provide details about how customising the delivery note template works in QuickBooks Online (QBO).

I can see how the functionality of directly customising a delivery note template would be beneficial to your business. However, this option is unavailable because its template will be based on the customisation of your Default Standard template.

You're correct that you'll have to modify the Default Standard template in the meantime, so it will be set as your preferred layout for delivery notes.
