Thanks for posting here today, @PMQMi.

I have some information about the time-out of sync error. We have a separate forum called Intuit Developer where you can post questions like yours. It's where you get answers from our programming experts related to QBO integrations and applications.

Please check out this link: https://developer.intuit.com/app/developer/homepage.

Additionally, you can contact ASP Support for further assistance in the importing process.

In case you need help with other tasks in QBO, feel free to browse this link here to go to our general topics with articles.

Reach out to me if you have other questions or concerns with invoices or the program. I'll be around for you. Take care and have a good one.
