I have and invoice that does not appear in revenue when I run a cash P&L but does apppear in an accrual P&L. It should appear in both reports. How do I fix this?

Hello there, cquick!

I can share some information about how the accounting methods affect the reports in QuickBooks Online. 

You first ensure the product or service items used in the invoice are under an income or sales account. Here's how to verify:

1. Go to the Gear icon, then select Products and Services.
2. Locate the item you used in the invoice, and click Edit at the far right side.
3. Scroll down and look in the Income Account field (see screenshot below). 
4. Click Save and Close when done. 

The cash basis of accounting recognizes revenues when cash is received. While, the income under the accrual accounting method is recorded regardless of when you're paid. 

In order for the invoice to show in your Cash Profit and Loss report, you first ensure to record its payment. Please note this report will follow the date of the invoice payment. 

On the other hand, the Accrual Profit and Loss report will show the invoice based on its date. Therefore, whether its paid or not, it will reflect. 

That's it! This should give you the information you need. 

Reach back to me if you have additional questions with the process. I'll be around!
