How can I change my payment method?

Let’s get the payment method changed, @kostakah.

Can you tell me which area you’re trying to update? There’s your QBO subscription, customer’s ways to pay a transaction, and vendor payments.

If it’s for a QuickBooks account, please note that only the Master or Company Administrator can change the billing information. Here’s how:

1. In QBO, go to the Gear icon and pick Account and Settings. 
2. Tap the Billing & Subscription tab, and then click the pencil icon in the Payment Method section.
3. Fill out the Payment Information window and select the box that authorizes the payment.
4. Hit Save to record the changes.

I recommend checking out these articles for the details: Subscription payment options for QuickBooks Online and Update payment information for your subscription.

When it comes to customer's payment options, set or edit this up through the Lists window. Follow these steps:

1. From the Gear icon, choose All Lists.
2. Click Payment Methods on the Lists page.
3. Look for the payment method you wish to update, and then tap the drop-down arrow in the Action column to select Edit.
4. Update the details and hit Save.

For more information about the process, please take a look at this article: Add or modify the accepted credit card types in QuickBooks.

Modifying the vendor payment method, on the other hand, can be done by reconnecting the right bank account or sending an invitation. See Change a vendor payment method to serve as your guide.

Know that I'm only a post away if you have additional questions or concerns. Have a fantastic day!
