I'll help with your question about running reports in QuickBooks, JackieMGMZ.
Can you tell us if a customer or job is attached to the expense transaction? The report will only include transactions that has data in the Customer:Job column when they were recorded. If not, QuickBooks will remove them when sorting out by Customer:Job.
Let's open the Check and make sure the customer is attached to it. Check out the screenshot below for additional reference.
Once done, go back to the Profit and Loss report and sort it again by Customer:Job. I'd also like to share this article for additional reference: Customize Reports In QuickBooks Desktop.
Let me know if you have follow-up questions. I'll jump right back to help you again.
