Hi there, @kubanorio.
Currently, the program's default form style won't allow you to change the font size for a particular word or number.
As a workaround, you can utilize the Import Style feature to create own form styles. Here's how to turn on the feature:
- Go to the Gear icon.
- Select QuickBooks Labs.
- Turn on Import Styles.
Once done, you can create own designs and import them into the program. For more details and samples, refer to this link: Import custom form styles for invoices.
Here's how to start the importing process:
- Go to the Gear icon.
- Select Custom Form Styles.
- In the New style drop-down arrow, select Import style.
- Select a form type.
- Select Upload your .DOCX file field, then find and select your .docx template.
- Select Next.
