Can we adjust the decimal in the Invoices?

Greetings, @zhengzhi8.

Welcome to the QuickBooks Community family. I'd be happy to help you adjust the decimal in the invoices in QuickBooks Online. 

Let's change the number format in your account settings.

Here's how:

1. At the top right, click the Gear icon.
2. Select Account and Settings.
3. On the left pane, select Advanced.
4. Click anywhere inside Other preferences.
5. Select your preferred Number format on the drop-down.
6. Click Save.
7. Hit Done.

That also changes the dollar amount's format in other transactions and reports. 

I've attached a screenshot for your reference. 

That should do it. Feel free to leave a comment below if you have any other questions about adjusting the decimal in the invoices. I'll be happy to help you further.

Hello,

I'm not using USD as home currency, and I need to change the current format to 3 digit decimal.

I couldn't find this option, is there any other way ?

The number format option is available in all QBO versions, kalghanim.

You'll see this option even if the home currency is not USD. However, if your access to the company file is limited or view-only, you won't be able to change the number format. 

Please know that QuickBooks Online does not have an option to change the decimal format to three digits. When you edit the number format, the changes will only take effect on how the numbers are displayed on the reports.

If you have additional questions, just let me know.
