Thanks for taking the time posting here in the Community, @Mariii12.
I'd be happy to help share some information about handling credits in QuickBooks Online.
There's no need for you to create a credit memo for each invoice that was overpaid since credit was already made upon entering it into the system. The credits will be applied automatically to the next invoice of your customer. To make this possible, you'll need to enable the Automatically apply credits option on your settings.
Here's how:
- Select the Gear icon at the top, then Account and Settings.
- Select Advanced.
- Select the Pencil icon in the Automation section.
- Check the box before Automatically apply credits.
- Select Save, then Done.
To learn more about this process, you may refer to this helpful article: Apply a credit from an overpayment.
If you need additional assistance with this concern, you may reach out to our Customer Care Team. They have an advanced tool that can walk guide you through these steps.
This information should get you going today.
Don't hesitate to reach back out to me if you have any other concerns with QuickBooks. I'll be around to help you out. Wishing you and your business continued success.
