We are using cloud version of quick book , we would like to integrate quick book with our sales which are using to enter our HIS system ?

Hi there, @info1659.

The apps you can integrate with QuickBooks depend on if they are listed in the Apps center. You can search for the app by logging in to your QuickBooks Online account. Then, go to the Apps menu and search for it. 

If you're able to find the app from the list, this means it's integrated with QuickBooks.

If not, you have to look for a third-party connector that could link QuickBooks and your inventory service provider. 

Please take note that the Apps menu isn't available for all QBO countries. In case you're unable to see it in your account, you can search for the app outside QuickBooks instead. You can also directly reach out to your sales provider if they can integrate with QuickBooks.

In case you need related resources while working with QuickBooks, please feel free to skim through the topics from our help articles.

Don't hesitate to tag my name in the comment section below if you have other concerns or questions. I'm always ready to help.
