Hi there, vonneyf.
I'll take that the invoice will automatically be closed after sending one. I'm here to share more information about it.
When you configure your QuickBooks account to apply for the credits automatically, the invoice status will change. If you want to receive the payment manually, you can turn off the Automatically apply credits feature. Here's how:
- From the Gear icon, select Account and settings.
- Go to the Advanced tab.
- Click the Edit (pencil) in the Automation section.
- Toggle the Automatically apply credits button to Off.
- Click Save, and then Done.
You can check this article for more information about the feature: Create and apply credit memos or delayed credits in QuickBooks Online.
I've also added this reference as your guide in recording customer payments: Record invoice payments in QuickBooks Online.
Keep me posted whenever you have concerns about recording payments.
