Recent updates to NRGship Pro for UPS include support for QuickBooks Online. Now you can easily ship from QuickBooks Online with ease from your Mac. Once configured, simply enter an order # to have destination information auto-populated. You can then capture weights from a digital scale and output labels to thermal printer or other device. After shipment, the order will be updated in QuickBooks so that tracking data is displayed for full visibility.  Contact NRG Sales for further information on integration with QuickBooks Online.
