Hello, otcpa.

I can see the urgency of getting your migration error resolved. With this, I'll guide you with the recommended solutions to help you complete the exporting process from QuickBooks Online (QBO) to QuickBooks Desktop (QBDT).

Internal error 1009 happens when QuickBooks isn't running, no company file is open, and the connection is prevented by an open window. If you haven't performed the resolutions above, I'd recommend doing so to isolate and fix the issue. Here are the following:

• Exit and reopen QuickBooks. Then sign in to your company file.
• Make sure there are no other windows open in QuickBooks.
• Update QuickBooks Desktop to the latest release or version.
• Use the clean install process.

In case the error continues even after performing the solutions above, I'd recommend contacting our Customer Care team. They can create a case that'll trigger an investigation and get the issue fixed in no time.

Also, you may want to check out this article to guide you in setting up your customers, vendors, items, and financial accounts after creating your QBDT company file: Get started with QuickBooks Desktop.

Please feel free to let me know in the comments below if you have other migration concerns or questions about entering data into QBDT. I'm always ready to help. Take care, otcpa.

I did all steps -QB update, clean install. It's still not working.

I even reached out to 5 different people in the customer support team and they were unable to resolve it. I reached out to Sherlyn, Samuel Anthony & Jayvee through Chat and Jay & one more person via call, none of them were able to resolve it.

You are using the trial version for QBD 2023 Enterprise, correct?

Try using the trial version for QBD 2021 Pro to make sure. Contact me in private and we can share the trial code later if required.

I am using the licensed version of QB Enterprise Solutions 23.0.

I had the same problem trying to convert data from QBO to QBD 2022 Enterprise and 2023 Enterprise. QBD 2021 was more reliable.

Can you ping me the link to download the trial version of QBD 2021

I am using Windows.

I called and someone at Intuit said I have to hire an IT person to migrate my data. I've migrated data many times before without a problem.

Use the trial version of QBD 2021 Pro.

I had the same error, and I found this article to be the answer I was looking for. Follow Step 3 exactly.
