How do i run a report for what we billed for 2018 and 2019?

I'll help you view these transactions in QuickBooks Online (QBO), @valerie_henry.

If you're looking for the 2018 and 2019 invoices, you can run the Invoices List by Date report in QuickBooks. This will show you the list of all invoices that you've created. Here's how:

1. Go to the Reports menu and look for the Invoices List report.
2. Click it to open and modify its report period. Simply click the Report period drop-down list and select Custom.
3. Modify the dates and click Run report.

In addition, you can customize this report to view the specific details that matter the most to your business.
