Maintaining The Connection
Initial Import
After the connection is established, Juno will automatically:

Create a tax preparation in Juno for each client. Please note, Juno does not consider a preparation used until you have actively started processing documents related to that work item by clicking into the preparation thus initiating the fetching of documents from Karbon
Sync any documents attached to their Karbon work items
Ongoing Sync
Once connected, the integration stays active. When you create a new work item in Karbon using the selected template:
The client will automatically appear in Juno
Any documents you add to that Karbon work item will sync into Juno automatically upon entering the preparation
There's no need to re-run any setup or manually trigger a sync for new clients.
Starting a Preparation
Step 1: Select a Preparation in Juno
Once you’ve established the Juno and Karbon connection you can start a preparation by clicking into a client’s preparation in the Preparer screen in Juno.
Step 2: Karbon syncs documents from the work item to Juno
Once you open a preparation Juno will automatically pull in the documents associated with the work item you have selected.
Once Juno indicates the sync from Karbon is complete click “Continue” to proceed to data validation.
