How do I add an alternative payment method ?

Since you're using an iOS for your QuickBooks Online account, I'd like to ask whether you want to accept a new payment method from your customers or update the card used to pay for your QuickBooks Subscription?

To add a new payment method from customers. Here's how:

1. Tap the Menu in the bottom navigation bar.
2. Go to Sales & Get paid, then tap Invoice Payments.
3. Under payment options, toggles can be enabled for Credit Card, Bank Transfer (ACH), or Tap to Pay on iPhone.

To change your QuickBooks Online subscription payment method, here's how:

If your QuickBooks plan is billed through Apple (In-App Purchase), you must update it directly via your iPhone's Apple ID settings:

1. Open your iPhone Settings.
2. Tap your Apple ID name at the top.  
3. Tap Subscriptions or Payment & Shipping to manage or add a new card.

If billed directly through Intuit, subscription payment methods cannot be changed inside the mobile app and must be managed on a mobile browser (Safari/Chrome):

1. Go to qbo.intuit.com on Safari or Chrome and sign in.
2. Tap the Gear icon (⚙), then Subscriptions and billing.
3. Next to your payment method, select Edit and tap Add New to enter a new card or bank account.
