I need to upgrade my subscription to link my Wise bank account but there are no alternative subscriptions available (searched through the app/google subscriptions)

Welcome to the Community space, Lucabarton.

I appreciate you for trying to look for an alternative subscription. Let me share insights and help you upgrade your subscription so you can link your bank account. 

Please know that you can still pay using Wise Bank or any bank if it's Visa and Mastercard payment processing networks. However, if it isn't, use other bank accounts with Mastercard, Visa, American Express, and/or PayPal.

On the other hand, before upgrading your QBO account, check out the available pricing plans to see which subscription level is right for you. Once done, let's go right through in achieving your goal. 

Here's how:

1. Login to QBO as the primary admin.
2. From the Gear icon, select Subscription and billing.
3. Ensure that your payment info is up to date.
4. Choose Upgrade your plan in the QBO section.
5. Look for available plans. Then, Choose plan.
6. There will be an on-screen step you should follow.

For detailed info, read this article: Upgrade or downgrade your QuickBooks Online edition.

If you want to learn whether to update the card on file, change your subscription, or just a few billing histories, you can scan this article: Manage billing, payment, and subscription info in QuickBooks Online.
