Glad to have you here, Alex.
I want to make sure you're able to convert your data from Jonas Software and into QuickBooks Online.
For this, we need to have you contact their support provider to help with the conversion or exporting your data. They can assist you with file creations and provide further help getting your data outside their software.
We also have a separate forum called Intuit Developers. There you can find engineers who can help recommend third-party conversion apps that works with QuickBooks Online. Click this link to our website: Intuit Developers Community.
If you have any more concerns about syncing applications with QuickBooks Online, feel free to post here again. I'll be right here to help you. Have an awesome day!
