The Quick Order Mode allows you to select the first item in a category in just one click. This is useful for merchants who do not need multiple level categories i.e. Tab > Category.
You can enable Quick Order Mode from QashierHQ:
Go to Product Management and select a category.
Select Enable Quick Order.
Now that Quick Order is enabled for that category, you will be able to instantly add the first item in that category into the POS current sale by selecting the category.
If you would like to select any other items in the category, press and hold on the category to go in.
