To add buttons to the POS touchscreen rather it be Departments, Products, Menu and also removing unused buttons. First, go to app.petrooutlet.com then Store Management.

Next, go to Registers then configure.

Scroll down until you see the different options: Product, Dep., Menu, and Unused.

Once you select the one you have to click on the option and drag it to where you want it.

Then go where it says Select a Dept. pick the department you want and it will also change the label name to that Department you selected as well.

This works the same for Products

As well as the menu option

And the unused option

Once you put the buttons you want on the POS Touchscreen, scroll down to the bottom until you see Save Changes. Click on Save Changes. Now your buttons are on the POS Touchscreen
