You can sell POS products under POS in the menu.
Under POS all available products can be filtered by category to find the corresponding product faster.
In this example there are 4 categories (marked in red). Under the categories "Clothing" and "Accessories" you will find the exemplary POS products.
The next step is to add the product to your shopping cart using the "Add" button. At the top right you can choose one of your customers. The payment method can be selected with a click on the green button "Payment" whereupon the purchase can be completed with "Payment".
