I wish to cancel my account with immediate effect.Please advise how I do this ASAP? Thanks

I can guide you on how to cancel your QuickBooks Online (QBO) subscription, @info-thecadenceg.

You can cancel your QBO account on the Billing & Subscription page. Then, your data will be available in read-only access for one year from the cancellation date.

To start with, open a web browser on your computer, not a mobile device. Then follow the steps below:

1. Sign in to the Intuit Account Manager.
2. From there, go to the Products & billing tab.
3. Select your company name, and find the product you wish to cancel, then select Cancel.
4. Choose why you're canceling your subscription from the choices. Once you’ve filled it out, select Continue to cancel.
5. You’ll see a page that details product benefits, and the last day you'll be able to use your subscription. Select Continue to cancel.
6. A pop-up confirming your subscription is canceled will appear, then you can select Got it.

Aside from that, you can also contact our Customer Support Team for assistance.

In case you change your mind, you can always resubscribe or reactivate your account as soon as you sign into your QuickBooks Online company. Learn more about this process by visiting this link: Resubscribe to or reactivate QuickBooks Online.
