Hello Sales51,
Welcome to the Community page,
There is no way in Quickbooks to create a delivery note template.
You can amend what is shown on it as the information is pulled from the master template in customer forms styles, which can be found in main cog wheel> under settings>customer form styles then click into the master template>content>and can amend any information in there.
That is the only place, to change anything on it. We have taken your feedback on board and will pass it to the developers as it may be something that comes out in the future.
