Good day, chrisjordan2015.
If your QuickBooks Online subscription is more than 60 days old, you can cancel the old subcription. You would have to start new and enter again all the information from scratch.
However if your subscription isn't more than 60 days, you can purge your company details.
Once done, you will be rerouted to your homepage.
Let me know if you have other concerns. Have a good day!
