Subscription- I want to change my subscription from itunes to direct debit, but it won't accept any my bank account, nor any other card or account

I'd like to help you update the information, LDowse.

To clarify, are you using your mobile app to update the account for your subscription? If so, you'll want to use the regular browser.

Here are the steps:

1. Sign in to QuickBooks Self-Employed in a web browser. Don't use the mobile app.
2. Select profile ⚙ > Billing info.
3. In the Payment Information section, click Edit ✎.
4. Update your payment information and select the checkbox to acknowledge the change and confirm your updates.
5. Enter your current address and new address in the next section.
6. Hit Update and then Close.

You can read this article for more details: Update your billing and subscription info in QuickBooks Self-Employed.

If you're still unable to update the account to direct debit, I recommend reaching out to our Customer Care Team. They can pull up your account in a secure environment and help you modify the account.

Here's how:

1. In your QuickBooks Self-Employed account, click Assistant located in the upper right-hand corner.
2. Type Talk to a human twice to see the Message an agent or Get a callback option.

Please feel free to leave a reply if you have more questions or other concerns with QuickBooks Self-Employed. Thanks.
