Let's get to the button of this, @welnok.
You'll want to go to your Billing and Subscription page and ensure you've canceled your account. Let me show you how.
- Log in to your QuickBooks Online (QBO) account.
- Go to the Gear icon.
- Select Account and Settings.
- Click the Billing & Subscription tab and ensure the status of your account is canceled.
If this is not the case, I suggest contacting our Support team. They have the access to check your account and investigate the reason for the charges. Here's how.
- Go to the (?) Help icon.
- Select the Search tab.
- Click Contact Us.
- Enter a brief discussion of your concern and click Continue.
- Choose either Chat with us (if you preferred messaging) or Give us a call.
You can also check this article for more details and ensure to review their Support hours so you'll be accommodated: QuickBooks Online Support.
I'm also adding this link that you can utilize in case you need to resubscribe to your account. This can seamlessly walk you through the process of reactivating your company.
Let me know in your reply if you need further managing your subscription. I'm just a post away from you. Keep safe!
