You can automatically set the system up so that orders are automatically set to despatched when shipments are created on a user level basis
With this setting enabled you will no longer have to click the despatch button once shipment created:
You should only use this setting with the courier tool installed & running, otherwise you will not get the option to print the label manually!
Enable Auto Despatch
To do this - for each user or packing station, navigate to Settings > User Settings > Picking Defaults
Then tick the option Automatically Mark Shipment as Despatch & Save in the bottom right:
The system will now automatically despatch orders as soon as shipment created successfully on the picking > scan actions screen and take you back to the picking screen ready for next scan:
