Good day, JacqiRose.
I'm here to share additional details about applying a credit to an invoice.
QuickBooks Online won't automatically apply the available credits if the automation is turned off. It's best to reach out to our Customer Support Team since you already uncheck the option and cleared the cache already. That way, they can further investigate and fix it as soon as possible.
You can follow these steps in contacting them:
- Go to Help and enter Talk to a human.
- Type in Credits, then click Show more > No.
- Click Talk to a human > Contact us.
Also, I've added this article if you need help on how to handle a customer credit or overpayment in QuickBooks Online.
Shoot me a reply if you need more help. Stay safe and I'm wishing you all the best!
