Is there a way to have a text line on a customer invoice without $0.00 showing in the amount column?

Howdy, theblanchettes. 

Removing the $0.00 in the amount column is not possible in QuickBooks. However, as a workaround that will help you achieve what you want. You can design your own template in MS Word, and import it in QuickBooks Online. This way, you'll be able to import and keep different templates with its design. 

Here’s how:

1. Click the Gear icon.
2. Click QuickBooks Labs.
3. Go to Import styles and click the switch button. 

Here’s how to import style:

1. Click the Gear icon, then select Custom Form Styles.
2. Press New style and then choose Import style.
3. You can click Download a sample invoice, to get the acceptable file by QuickBooks. 
4. Tap browse the document and hit Next.
5. Then QuickBooks will show you the status, if it’s accepted then tap Next.
6. After the confirmation, then click Save and you can put the Template name.
