Normally, QuickBooks Online sends an email notification when a trial subscription is about to end, 088jn.
If you only signed up for the free trial and did not enter any payment information, you don’t need to worry about any charges or active subscriptions linked to your account.
Please note that the QuickBooks trial subscription will automatically end after 30 days. However, if you wish to cancel your trial immediately, you can follow the steps outlined in this article: Cancel your QuickBooks subscription or trial.
