How can I transfer quickbooks desktop company to online when I mistakenly set up a new company online when I set up subscription before transferring the desktop company?

Thanks for posting in the Community, president.

It's my pleasure to assist you with your concern about transferring your QuickBooks Desktop (QBDT) file to QuickBooks Online (QBO).

To successfully import your QBDT company file, please make sure to select the correct QBO account where to transfer the data.

 If you want to cancel the company that has no data from QBDT and continue to subscribe to the new company, yes, it will be associated with the subscription.

Additionally, if you'll be migrating from the QBDT US version to QBO International, it's possible that it created a new QBO subscription with the same region as the QBDT. If that's the case and you still want to continue with the paid subscription without the data, you'll want to manually export the info from QBDT and import it to QBO.

You can read through this article for guidance: Move your QuickBooks Desktop file to QuickBooks Online. Although this is for the US, but the process is still applicable to the Global region.

Keep me posted if you have clarification or additional QuickBooks concerns. I'll be around to help you.

Where is your company located?

Which QB Desktop year version and country version do you have?
