I have duplicate entries under the customer name and the job. How do I delete the postings under the customer name?
Creating a transaction under the customer's job is posted to both the customer and its job. If you delete the entry under the customer name, it will also delete the entry under the customer's job.
That will clarify your concern for today.
If you need to access various job reports, you can go to your Reports menu, then select Jobs, Times, & Mileage.
I've also added this article if you need to customize job reports: Customize reports in QuickBooks Desktop.
Please know I'm always here if there's anything else you need with the entries posted on your customer. Thank you and have a great day ahead.
