I want to connect bluesheet with Quickbook but it cant connect

It's good to see you here in the Community, vera.

QuickBooks Online (QBO) allows integration with several third-party apps and software. Since you can't connect Bluesheet to QuickBooks, I recommend contacting their customer support team. This way, they can confirm if Bluesheet can integrate with QuickBooks and help you with the steps.

As always, you can visit our QuickBooks Community help website if you need tips and related articles in the future. 

Feel free to visit our Community forums again if you have other questions about QBO. I'm always here to help.
