Unfortunately at this time, it doesn't appear we connect with Tenant Cloud directly. That being said, you'll want to contact TenantCloud's support to help you with the process and check the settings for the necessary data to flow. They would be able to share information about how this app works and how the information can be added to QuickBooks Online. Additionally, if you search our app store for QuickBooks Online, there are several options for property management that you may be able to utilize.
