Reconnect to QuickBooks
The connection between Sunrise's internal bookkeeping assistant and QuickBooks Online needs to be authorized again. This happens if the app was disconnected or the authorization expired.
Only a QuickBooks user with Master Admin and Company Admin rights can reconnect. The administrator goes through Intuit's own sign-in and consent page. This site never asks for or stores any QuickBooks credentials.
If you aren't the administrator, contact the Sunrise administrator. You don't need to do anything else.
