Is it possible to run a report by card accounts?

Good morning, jfernandez1.

Thanks for bringing your question forward here in the Community. I'd be happy to lend a hand with account reports in your QuickBooks Online account. 

To view the data you're looking for I recommend trying the Transaction Detail by Account Report. This report breaks down each transaction that was made in each account you have set up in your QBO account. You can also use the filter and customization options to see even more specific data. Here's how:

1. Click the Reports tab in the left navigation menu.

2. Enter Transaction Detail by Account in the search field.

3. Set the desired date range and add any other filters by selecting the Customize button in the top right corner.

4. Choose Run Report when you're all finished.

I recommend checking out the following linked article for additional info about customizing reports in QuickBooks Online.

Please don't hesitate to reach back out if you have any other questions. I'm only a comment or post away.

Would I also be able to customize this report to show me which of these expense transactions within these accounts I have invoiced already? 

Thanks for getting back to us, @jfernandez1. I'm happy to address your concern about customizing report.

You can run a custom Transaction Detail by Account report to see which transactions are linked to invoices. You can filter A/R Paid and Transaction Type to Invoice. I’ve attached a screenshot below for your reference.

I also have some additional articles about managing a wide range of reports in QBO:
Run reports in QuickBooks Online.
Memorize reports in QuickBooks Online.

If you have any other additional questions about this topic add a comment below. I'm here to get back to you as quickly as possible. Have a good day!

And running a report to show expense transactions for my credit card accounts that I have not invoiced?

Thank you for getting back here in Community, @jfernandez1. Let me help you generate a report that shows the expense transactions in QuickBooks Online (QBO).

We can run a custom Transaction Detail by Account report. This report shows the expense transactions from your credit card accounts. You can customize it by following these steps:

1. Go to Reports menu.
2. Search the Transaction List by Account, then hit the Enter key.
3. Click the Customize button, then go to the Filter section.
4. In the Transaction Type drop-down, select Expense.
5. Select your credit card accounts in the Account drop-down.
6. Click Run report.

I've also included these articles that you can use when pulling up and saving a customized report in QuickBooks Online:

• Common custom reports in QuickBooks Online.
• Customize reports in QuickBooks Online.
• Memorize reports in QuickBooks Online.

Please let me know if there's anything else that I can help with your reports. I'm always here to assist. Have a great day!

But there is no way of telling from this report whether that expense needs to be billed. I want to make sure I am not leaving any expenses left unbilled. Is this possible?
