I have created multiple companies by mistake. How to get rid of them?
You can cancel the other companies, mariam2.
If the other account has the same email address to the original one, you can go to the Gear icon and select Switch Company to see all the accounts. Then, just click on the company that you wanted to cancel. Here's how:
Go to the Gear icon and choose Account and Settings.
Select Billing & Subscription.
Click the Cancel trial link in the QuickBooks section. Then, select Continue to cancel to confirm.
Do the same process in the Payroll section to cancel the payroll.
Answer the short survey.
Don't hesitate to post again if you have other questions.
