The process for canceling your QuickBooks Online (QBO) subscription varies depending on where you signed up, Diana.
If you purchased your subscription through the Google Play Store, you can't cancel it directly within the QuickBooks mobile app.
If you signed up through a mobile app store, you'll need to visit that app store to cancel your subscription. For guidance on canceling a subscription purchased from the Apple App Store or Google Play Store, follow the steps outlined in this article: Cancel your subscription.
If you bought your subscription directly from Intuit's website, you can cancel it through a web browser by following these steps:
1. Sign in to your QBO account.
2. Click the Gear icon in the upper right corner, then select Subscriptions and billing.
3. Find the product you wish to cancel and click Cancel.

4. Confirm your cancellation by selecting Continue to cancel.
