Hello again, @abricoetzer. I appreciate you following the recommended steps provided by my colleagues above. I have another solution for you to help fix this issue.
Let's check the billable accounts that we set up and make it assigned to a single account. Here's how:
- Click the Gear icon at the top.
- Select Account and Settings.
- In the left menu, hit Expenses.
- Go to the Bills and expenses section and click the pencil icon.
- Choose In a single account, then Save.
- Hit Done.
Once finished, try to create a Purchase Order again and check if it works.
Get back to me if you have any other questions by leaving a comment below. I'm more than happy to further assist you. Have a great day!
