Hi there, rbs22books-gmail.

I appreciate your update regarding your concern. It's great to hear that the steps provided by my colleague worked. I'm here to help you so the change reflects on all statements.

If you run a nonprofit company, an invoice is labeled as a pledge. As stated by my colleague, you can update your Company type on the Account and Settings page. Updating your company type from nonprofit will automatically rename your invoice form to pledge.

Additionally, when you create a statement for a customer, you'll see that the documents will say invoice instead of pledge.
