We are glad to see you've come to the QuickBooks Community to get help with syncing your Joist account.
Joist is a third-party app that has its navigation instructions. So I've searched on the web on how to connect QuickBooks to their app. As I have checked their support page, it says that they are using QuickBooks Sync to transfer transactions from Joist to QuickBooks. It is one of the lists of powerful features available exclusively to Joist Pro subscribers.
I can guide you on how to search for the steps to connecting Joist using QuickBooks Sync:
Open a search engine (for example: google.com).
Type The Joist Help Center.
From the Joist Support Community page, enter How do I get started with QuickBooks Sync?
Please keep up posted if you've got any questions about syncing your transactions. We are here to help.
