How do i delete expired trial company?

Hello there, @iskandar.

Allow me to share some insights about an expired trial subscription. I'll make sure to ease your mind and not to worry about the data. 

When a trial subscription is expired, QuickBooks Online will keep the data for a year so you can continue tracking if ever you decide to subscribe again. QuickBooks will delete all information after that.

Refer to this article for more information about canceling a subscription: Cancel your QuickBooks Online subscription.

Additionally, if you decide to come back, you can check on this article to know more about QuickBooks Online and how it can help you track your business.
