In Multiple Create Invoicing Can I add Message On Invoice? or Is there a way to Set up A default Message on Invoice?

Thanks for posting to the Community, @jane36.

Yes, you can set up a default message by creating a customized form and use it as a default form for your invoices. It enables you to include a message on the Footer section of the Invoice.

Here's how:

1. Go to the Gear ⚙ icon and then select Custom Form Styles.
2. Click New Style, then select Invoices.
3. Select the Content tab.
4. Click the Pencil✎ icon on the Footer section.
5. Hit Done.
   

Once done, set it as a default invoice form by clicking the drop-down arrow on the Action column.

Well done! You successfully set up your default message.

You can also add a default email message on invoices as well as with other sales forms. You can utilize the Gear icon and set up the  Message section under the Sales setting in Account and Settings.

Let me show you how:

1. Go to Gear ⚙ on the top right.
2. Select Account and Settings.
3. Choose the Sales setting.
4. Click the Pencil ✎ icon in the Message section.
5. Click Save.
