Add the items the customer wishes to purchase to your cart (as you would for any other order).

OPTIONAL: Assign the customer & employee to the check out cart.

After adding the items to the cart, click "Total" at the bottom of the screen.

After clicking total, click Cash for the payment method on the total screen.

The POS will ask you how much cash the customer is paying with. It will default to the entire purchase amount.

After verifying the charge amount, the cash drawer will open for you to accept the cash, and any change due will be shown in green at the bottom of the screen.

Once all cash has been collected, it will show green as a payment method.

When it is green, hit complete order and either print the receipt or email the receipt to the customer.
