Quickbooks has made me 2 accounts with 1 email. I was using 1 account and have had transactions go through that one now thats been cancelled, can I transfer the details?

I have an easier way other than transferring the data to your other account, rhyshillplasteri.

You'll want to resubscribe your canceled account so you don't need to transfer all the information from one of your accounts to the other. To do this, you can follow the steps below.

1. Log in to your QuickBooks Online company.
2. Select the Gear ⚙ icon at the top.
3. Under Your Company, choose Account and Settings. 
4. Select Billing & Subscription, then Resubscribe and enter the updated billing information.
5. Select Subscribe.

After you have resubscribed, you can call our phone support team so they can assist you in transferring your subscription rate to your other account to prevent any double charges. Here's how you can reach them: 

1. Select the Help menu.
2. In the Assistant window, enter Talk to a human.
3. Enter your brief concern in the field.
4. Type in/click I still need a human until you see the Get help from a human option.
5. Choose a way to connect with our support.

For your reference, you can also export your data from your books, then manually enter them if you want to use the other account instead of the canceled one: Export reports, lists, and other data from QuickBooks Online.
