Thanks for checking this with us, @Anonymous,
Welcome to our forums. I can share some insights about charging a credit card in the Merchant Service Center.
Typically, when you update the card before the settlement time which is 3:00 PM Pacific Standard Time or 6:00 PM Eastern Time, the credit card should be charged automatically. However, if the charge didn't go through on the updated CC, I'd recommend getting in touch with our QuickBooks Payments Support so they can help check the status of your payment.
For security reasons, they can check your account in a secure environment and can give in-depth information about processing Merchant payments. Here's how to contact us: Contact Payments Support
Please update me on how the call goes. I want to make sure you're all set with your credit card charges. Have a good one!
