how can I stop my Quickbooks Online trial. I've made a decision about what I want to do.

Let me help cancel your QuickBooks subscription, Rob0711.

The trial subscription will be cancelled automatically after the 30 days trial period. You'll then receive an email about the cancellation once QuickBooks cancelled your account.

I want to make the process as easy as possible for you. Let's start by logging in to your Intuit account and cancel the subscription from there. 

Here are the steps you can follow:

1. Log into the Customer Account Management Portal (CAMPs), your Intuit account.
2. Choose QuickBooks Desktop.
3. From the Products & Services area, find your subscription or service, then click Details
4. Verify this is the product or service you no longer need, then select Cancel Service under the active status.
5. Please let us know why you are leaving so we can improve our services. After providing any details (optional), click Continue to cancel.
6. Confirm your cancelation by selecting Cancel Now.
7. You will see a confirmation message as well as receive an email.

If you need more information about QuickBooks cancellation, follow these steps: How to cancel your QBDT Subscription.

Additionally, I've also added pages about handling your subscriptions, company information, policies, and other relevant topics. 

• View, manage or update your Intuit account in CAMPs
• QuickBooks Desktop cancelation policies
• Activate QuickBooks Desktop

Please let me know if you need further questions. I'll be around to help. Have a great day!

As long as you didn't submit any payment credential, you can ignore your trial account. Then you can still purchase the one time license for QB Desktop 2021 from some partners if required.
