# Checkout

> Control how guests pay at the Kiosk: Square integration settings, discount and marketing codes, and the checkout experience in each profile.

Everything that shapes what happens when a guest pays lives here. Some settings apply to your whole Square integration. Others are set per profile in Remy, so different Kiosks can check out differently.

## Allow \$0 orders

By default, guests can't check out with a total of $0. Turn on **Allow $0 orders\*\* if you want to let them, for example when a reward or discount covers the full order.

<Steps>
  <Step title="Open your menu settings">
    In Remy, go to the **Menu** tab and open **Square Integration**.
  </Step>

  <Step title="Turn on $0 orders">
    Turn on **Allow \$0 orders**.
  </Step>
</Steps>

Turn the setting off again to go back to requiring a payment on every order.

## Service charges

A **service charge** adds a percentage-based fee to every order on a Kiosk. Use it to offset kiosk service fees. You turn it on per profile in Remy, so you can charge it on some Kiosks and not others.

<Steps>
  <Step title="Turn on Service Charge">
    In Remy, open the Kiosk profile, scroll down to **Other Checkout Settings**, and enable **Service Charge**.
  </Step>

  <Step title="Set the amount and label">
    Tap **Customizations** to set the charge percentage and the label guests see. The row shows your current settings — for example, **1.5% · "Service fee"**.
  </Step>

  <Step title="Save">
    Save the profile. Every Kiosk assigned to it starts charging the fee.
  </Step>
</Steps>

#### What guests see

The charge appears as its own line in the **Order Summary**, between **Subtotal** and **Tax**, using the label you chose. It is included in the **Total** the guest pays.

To stop charging the fee, switch **Service Charge** off in the profile.

## Fast-Lane: check out at \$0

**Fast-Lane** is a setting you turn on in Remy that makes every order on that Kiosk check out at **\$0.00**. It is a device-level toggle, not a per-order action — there is no coupon to type in and nothing for your staff to do at the Kiosk while it is on.

With Fast-Lane on, the Kiosk works exactly as it normally does. A guest browses the menu, builds an order, and checks out through the usual flow. The only difference is the total.

What stays the same:

* **Orders still reach the kitchen.** They print and route as usual, including to a KDS if you use one.
* **Order data is still recorded, item by item.** You can still see how much of each item was ordered, so a Fast-Lane service reports the same way any other service does.

Fast-Lane is intended for **prepaid events** — an organizer has paid a lump sum up front, and guests order freely against it without paying at the Kiosk.

Turn Fast-Lane off in Remy to return the Kiosk to normal pricing.
