I’v had an invoice part paid, how do I generate a statement for the remaining outstanding?Thank you.

It's great to have you here, @g-mitchell,

You can create a Balance Forward statement for that customer to show the total amount due and any credit balance from the last invoice.

Here's how:

1. Go to the Create icon, and select Statement.
   
2. Choose Balance Forward for the Statement Type.
   
3. From the Recipients List, mark the customer name.
4. (Optional) To print or view the file before saving, pick Print or Preview at the bottom.
5. Hit Save and send or Save and close.

To know more about using customer statements, see this article: Account Summary on an invoice.

Another way is running a Customer Balance Detail report. Follow the steps below:

1. Click the Reports menu.
2. Locate and select Customer Balance Detail in the Who owes you section of the Reports screen.
3. Update the Report period and the Aging method.
4. Tap the Customize button then proceed to the Filter menu.
5. Choose Customer and pick the name you want to pull up.
   
6. Hit Run Report.

I've included some articles to guide you with the reporting process in QBO:
