I'm here to help you cancel your account, ahmadonar.
The steps for cancelling your QuickBooks account vary on how you have purchased the subscription. If bought directly from Intuit, you can perform the process below:
Open a web browser on your computer, not a mobile device.
Additionally, for a year following account cancellation, you will have read-only access to your data. Before we delete your data, you will have the opportunity to resubscribe within the allotted period.
If you need more assistance managing or cancelling your QuickBooks subscription, I'm only a post away. To keep us informed about your questions on this topic, you can tag me in your responses.
