Thank you for getting back to us, @leanne-wetaskiwi.

I'm here to help ensure the vendor's auto-apply credits is turned off.

You're correct. The Automatically apply credits option is specific for customer transactions. Since it is vendor credits, you can turn off the Automatically apply bill payments option. Please know that if this option is turned on, it'll automatically apply credits to the oldest existing bill. To turn it off, you can follow the steps below:

1. Click the Gear icon, then select Account and Settings.
2. Go to the Advanced menu and select Automation.
3. Disable the Automatically apply bill payments option.
4. Select Save, then Done.

You might want to review all your vendor transactions in the future. You can go to the Expenses menu and select Vendors. Then, go to the Transactions List tab.

The Community forum is always open to help you again if you have further questions about your vendor transactions. I'm always around if you need any help, @Amber3GFG.
