Hello, AM Quadrant,

The Bill to section is not adjustable. If you'd like, you can submit feedback about this. That way, our engineers will know that you want an option to adjust it. From your QBO company, just click on the Gear icon, choose Feedback, and enter the details.

You can also find and vote on other ideas that you like on the Customer Feedback for QuickBooks Online page.

If you have other concerns about customizing form styles, feel free to go back to this thread. Take care always.
