About customer checkout

In the Square Retail POS app you can access the Checkout tab from the main menu. Once you’ve finished building your customer’s cart, you can checkout your customer and complete the sale. Checkout is where you can build your cart and accept your customer’s payment.

Before you begin

Adding items to cart: If you need to learn more about adding and removing items, scanning an item’s GTIN number, or saving your customer’s cart for later, check out the Support article Build your customer’s cart in the Square Retail POS app.

Sales tax: Once you’ve created taxes from your Square Dashboard, you can apply sales tax or any other applicable tax to item sales. Taxes can be location-specific or applied across multiple locations. Review Create and manage your sales tax settings for detailed instructions on setup and editing your tax settings.

Discounts: In order to add a discount to your cart, first make sure you’ve created one from your Square Dashboard or from the Items tab in your Square Retail POS app. Review Create and manage discounts to learn how to create automatic discounts for specific items and categories, holiday specials, or limited time offers.


All discounts (cart or item level) automatically default to show the item level on your customer’s printed and digital receipts, providing transparency to buyers on how much each item costs. Item-level discounts will always be itemized on receipts. Also your cashiers can clearly see how much a returned item is worth, expediting the return process.
