Hi advance-c,
Yes, you can update the payment method for your QuickBooks Online subscription. The process depends on how your subscription was originally set up.
If you only want to update the payment details for your Apple account, you can follow the steps outlined in this article: Update Apple account payment method.
If you want to switch your payment method from Apple to Google Play or directly to QuickBooks Online, I recommend contacting our Live Support Team. They can assist you with transferring your billing information to a new payment method. Please ensure you reach out during their support hours. You can use this link for reference: Get help with QuickBooks products and services.
We'll be right here if you need anything else or additional assistance.
