To clarify, are you trying to make a payment for your QuickBooks Online subscription or manage payments for customers within QuickBooks? Have you encountered any error messages while processing the payment? Any additional information would be appreciated and could help us provide a more accurate resolution.
Payment failures are often caused by outdated billing information or temporary maintenance issues on your bank's side.
To resolve this, please ensure that your payment information is up-to-date. If the issue persists, please check with your bank to confirm whether they are experiencing ongoing maintenance.
If you are referring to a subscription payment, please check out this article for steps to resolve payment failures: Fix “my subscription payment failed” issues in QuickBooks Online.
