Welcome to the Community, @enrico3.
When customizing the invoice template, we can't remove the subtotal, tax, deposit, and total lines before the balance due line.
Please be informed that as of 06/29/21, new QuickBooks Online accounts will no longer have access to the Import Styles feature inside QuickBooks Labs. Existing accounts can still save and upload DOCX templates.
The Import Style function will be phased out (even for those who have it enabled now), and all customers will have to utilize the Standard styles instead. The Invoicing team has laid out a timeline to follow, and we will get updates for this in the upcoming months.
Additionally, I’ve included these articles that’ll help you design and import custom form styles for your forms in QuickBooks Online.
If you have any further questions or concerns about customizing form styles, please know that you can always tag my name. I'm here to help you in any way I can. Enjoy your day!
