Can I delete customer credit card information?

Hi there, s3proservices. 

I understand how beneficial it is for your business to delete the customer's credit card information.

I'll provide another way to do this in QuickBooks Payments.

Once you've saved the information, we're unable to delete it. Otherwise, we can only modify it to keep the information up-to-date. That said, I suggest forwarding this feedback to our Product Developers so they can add this recommendation to future product enhancements.

I'll show you how:

1. Click the Gear icon and choose Feedback.
2. Enter your feedback Suggestion.
3. Press Next.

To help you manage your customers moving forward, you can see this article for more details: Add and manage customers in QuickBooks Online.

I still can't delete or overwrite the information with 4111-1111-1111-1111

please advise

I appreciate you for taking the time to follow my colleague's steps, s3pro. 

Before we begin, may I ask if you have encountered any specific error or prompt as you overwrite the credit card information? This allows us to identify what's the best course of action.

In the meantime, I suggest using other supported or private web browsers to eliminate any potential issues caused by browsing history or cached files. Here are the shortcut keys for accessing private browsers:

• Google Chrome: press Ctrl + Shift + N
• Mozilla Firefox: press Ctrl + Shift + P
• Microsoft Edge: press Ctrl + Shift + N
• Safari: press Command + Shift + N
