You're welcome, Baabs.

Yes, you can upload your client's information by updating their company file to the version you're using to ensure compatibility. The file will remain accessible as long as the QuickBooks Desktop version matches the company file's version year.

Please note that this process is irreversible. Once the company file is converted, it can't be reverted. Since the company file has been updated, you can't transfer the information back to your client.

For additional questions, reply here. We're here to provide you with the support you need.
