Connect or reconnect QuickBooks

Access to MangoGroup Balance API is by invitation. To connect a QuickBooks Online company, or to reconnect one whose authorization has expired or was revoked, you need an invitation code from MangoGroup OÜ. Request one at info@mangogroup.eu.

You will be sent to Intuit to sign in and choose the company to authorize. The app only reads account data. You can disconnect at any time, see Disconnect. If you received a full invitation link, you can simply open it instead.
