I understand the importance to transfer the data so you don't have to do add them manually. I'll be happy to provide you steps on how to do it. You need to export the data from the trial account and import them to the new account.
Here's how:
To export the data:
On your QuickBooks account, go to the Gear icon.
Select which data you'd like to export.
Click on the Export to Excel button.
To import the data:
Log in to the new account, then click on the Gear icon at the upper right.
Under Tools, choose Import Data.
Select the type of data that you'd like to import.
