Invoices and Credit notes marked to be sent did not appear on our report (Saved or sent invoices and credit notes). The CN was ticked as verified in the audit history

Don't sweat, @Jualande. Let me help make sure your sent invoices and credit notes show on a report.

May I know what specific report you're trying to pull up? This way, I can further assist you in customizing it.

For now, I suggest running the Transaction List by Customer report. And make sure the reporting period is correct. It's one of the possible reasons why your sent invoices and credit notes don't appear. 

Here's how:

1. Click Reports from the left menu.
2. Search for Transaction List by Customer report.
3. In the Report period drop-down, select the date when the invoices and credit notes are created.
4. Hit Run report.

Once done, you'll be able to see the sent invoices and credit notes on the report.

Keep in touch if you need any more assistance with this, or there's something else I can do for you. I've got your back. Have a good day.
