Hi there,
QuickBooks Online makes it easy to customize your invoice template and I'll be happy to show you how.
Here's how:
I recommend browsing through the customizing options to see where you'd like to add the Direct Deposit details. For more info, I recommend checking out this helpful article from our Community: Customize invoices, estimates, and sales receipts in QuickBooks Online.
Give this a try and if you need further assistance, don't hesitate to reach out to our support team using this link.
Thanks so much. I have a last question around how to make the customized invoice the default master invoice. Can't seem to find out how.
You're welcome. QuickBooks operates in a sticky mode. This means the program uses the last template you used when creating a new invoice. There isn't a default setting you can make for a template. Feel free to ask questions. I'm here to help.
