Invoice goes straight to paid and doesn’t send to the customer.

Hello there, @bkpropertymainte.

It's nice to have you with us in the Community today. I'd be glad  to help you on how to fix the automatically paid payments in your QuickBooks Online.

It could be that your settings for automatically applying bill payments and credits are turned on. This functionality could turn your open bills into paid ones.

We can see if the feature is already turned on by doing the following:

1. Click Gear icon.

2. Go to Account and Settings tab.

3. Find Automatically apply bill payments under Automation tab. You have an option to disable if you want.

Also, the bills paid with vendor credits are tagged under the payment transaction. I’ve attached a screenshot to visualize this information. To check:

1. Go to Expenses from the left panel.

2. Click the Vendors tab at the top.

3. Select and open a vendor.

4. Open the paid bill from the vendor’s transaction lists.

5. Click the payment maid link under PAID then click the Date link.

This will show the screen with the bills associated with the payment.

I've included an article on how to record invoice payments in QuickBooks Online.
