Hello there, @SunshineTim.

The Pledge term will appear in QuickBooks Online when a user has selected a non-profit organization.

The customer statement shows depends on what term your QuickBooks Online is using. Yes, you're right that changing the word from the template will not apply to the customer statement.

You'll want to toggle another company type. Then, send the customer statement to your client. If you want, you can print them (customer statement using Invoice term).

1. Go to the Gear icon.
2.  Select Account and Settings under Your Company.
