Good afternoon, Ned49. 

Thanks for stopping by the Community. Your bookkeeper is correct in that you cannot add all those specific fields to your invoice template. I can see how that would be very beneficial to you and your business and many other business owners alike, so I'm going to mention this to our product engineer team to see about this feature getting added to a future update. You can keep an eye on the QuickBooks Blog, as that's where the most current information from Intuit is updated about changes being made in-product. 

I'm also including a helpful link for you to check out that highlights the invoice customization process in QuickBooks Online. 

Should you need any other assistance or have the desire to reach out to our support team as mentioned above, you can click this link to find the steps to reach them. 

If there's anything else I can help with, feel free to post here anytime. Thank you and have a lovely afternoon.
