# POS

The point of sale or point of purchase is the time and place at which a retail transaction is completed. At the point of sale, the merchant calculates the amount owed by the customer, indicates that the amount may prepare an invoice for the customer, and indicates the options for the customer to make payment.

In this section, users have three options for interaction: Category, Product, and Live Storefront.

Here, users may need to add categories and their corresponding products.

Note: Users must set up the category first to list the products.
