I appreciate you for performing all the troubleshooting steps to resolve this issue, @ben_g.
Yes, you're right FIFO will base on the date of the invoice and receipt of a purchase order. It's an accounting method in which assets purchased or acquired first are dispose of or the firsts sold.
Also, I'd like to inform you that this issue has already been reported to our product engineers/developers. I know that you already called but I'd still suggest contacting them again so you'll be added to the list of affected users. Once added, you'll automatically receive an email notification with the latest updates. Just provide this investigation number for easy tracking: INV-35069.
Here's how you can get in touch with an agent:
- Open QuickBooks.
- Go to Help.
- Select QuickBooks Desktop Help.
- Click on the Contact us link and choose a topic.
- Enter your account information and click on the Submit button.
- Click on the Start a Message button
For now, the only options we have are to work in single-user mode or to turn off FIFO as a workaround.

Know that I'm always here if you need anything else. Take care and have a good one.
