By the end of this guide you will have rung up a sale in the POS, taken the payment and printed the receipt.

## Before you start

You need a product with stock in the warehouse you sell from. If you have none yet, [add your first products](/app/help/add-your-first-products).

> **Warning:** A product with no stock in the chosen warehouse doesn't go into the cart. To sell it anyway, turn on **Allow overselling** in **POS Settings**, the gear at the top of the POS. Only roles allowed to change POS settings see the gear.

## Open the POS

Click **POS** in the top bar, or open [Sales › POS](/app/pos). The till fills the screen: the cart on the left, your products on the right, and along the top the register, the warehouse, the product filters and the customer.

*The POS. Pay Now, at the bottom right, stays grey until the cart holds something.*

## Ring up the sale

1. **Check the warehouse.** The POS opens on your shop's warehouse. With more than one, click **Warehouse** at the top and pick the one you sell from.
2. **Choose the customer.** **Customer** starts on walk-in-customer, for a sale to someone you don't keep a record of. Click it to open **Select Customer**, type a name or phone number, and pick them. **Quick Add Customer** adds a new one without leaving the till.
3. **Add the products.** Click a product in the grid, or type its name or code in **Scan/Search Product by Code Or Name** and pick it. **Scan** reads a barcode with your camera.
4. **Check the cart.** **Current Cart** lists what you added. Use − and + to change a quantity, the pencil to change a line, and the x to take it out. **Tax %**, **Discount** and **Shipping** sit below the items.
5. **Click Pay Now.** It is at the bottom, beside **Total Payable**.

*Select Customer finds a customer by name or phone number.*

*The cart. Each line has its own − and + buttons and a price list (Retail Price).*

## Take the payment

1. **Check the amount.** In **Payment Checkout**, **Amount** already holds the total.
2. **Pick how the customer pays**, for example **Cash**.
3. **Enter what they gave you.** Type it in **Amount**, or click one of the amounts on the right, such as **$ 20.00**. **Change** shows what to give back.
4. **Click Pay.**

*Click an amount on the right when the customer hands over a round sum. Change works out what to give back.*

To split one sale across two payment methods, click **Add Payment Method**. A part you don't take stays as **Balance**, owed by the customer.

## The receipt

The receipt opens as soon as the sale is saved, with its reference (such as SL\_0375), your logo and details, the items, what was paid and the change. **Print** on the receipt prints it. [Settings › POS Receipt](/app/settings/pos_receipt) decides what the receipt shows, and **Print Invoice automatically** in **POS Settings** sends it to the printer every time.

*The receipt, ready to print. The QR code opens the sale's invoice.*

## Where your sale shows

- **Sales › All Sales** lists it. [Open All Sales](/app/sales/list).
- The dashboard counts it in **Total sales**.
- **Today Sales**, at the top of the POS, shows the day's sales and payments.

> **Tip:** With more than one warehouse, set **Default Warehouse** in Settings › System Settings, on the **Defaults** tab, so the POS opens on that one every time.

**Hold** keeps the cart for later, and **Recent Drafts** brings it back. The **Register** button at the top opens a cash register with your opening cash: see [Open and close the register](/app/help/open-and-close-the-register).

## What's next

To keep your stock right, read [Count and adjust stock](/app/help/count-and-adjust-stock).
