When I receive a payment from a customer the credit memo even through ticked off and the total is correct with this being deducted does not print only shows the invoices

Hi Nanette1976,

It's nice to see you reaching out to Community.  I can see how the absence of a customer credit can raise some concern.  QuickBooks Online provides additional options for customizing current features specific to your business needs.  I'd be happy to assist.

Based on the information you've provided, QuickBooks will automatically apply credit memos to customer invoices when the feature is turned on.  If you'd like to manually apply credit memos, you can disable the auto-apply feature.  Here's how:

1. Click on the Gear ⚙ in the top right and select Account and settings

2. Choose the Advanced tab

3. Hit the Edit ✎ in the Automation section

4. Set the toggle to off, for Automatically apply credits

5. Hit Save, then Done

For your reference, here's an article with additional information for credit memos.

Please don't hesitate to reach back out if you have any other questions.  We're here for you!
