Add parent customer drop down not showing up

Thanks for bringing this up to us, @robfinlon812.

We have an ongoing investigation in regards to the inability to select a Parent when creating a sub-customer. Our product engineers are now prioritizing this so you can get back to your business as soon as possible.

I recommend giving our Customer Care Team a call to add your account details to the list of affected users. This way, you'll receive an update as soon as a fix becomes available.

Here's how you can reach out to them: 

1. Click the Help menu in the upper-right hand corner and click Talk to a human.
2. Type in "Talk to a human", then press Enter.
3. Look for I still need a human and click on it.
4. Select Get help from a human.
5. Choose between Chat with us, Schedule an appointment, or Have us call you.

Please check out our support hours to ensure that we address your concerns on time.

Also, our Help articles might have something that can help you with your other QuickBooks concerns, too. Just make sure that the topic is set as "QuickBooks Online" to browse for related posts.
