• Updates help you follow the rules.
• Automatic updates save time.

Note: Update your system when the store is closed. This stops sales from being interrupted.

Sales

Add Items

You start every sale by adding items to the cart. Scan each product’s barcode with the scanner. If an item does not have a barcode, you can search for it by name or SKU on the screen. Some pos machine pos terminal machine setups let you tap the item on a touchscreen menu. Double-check the item name and price before you move on. This step helps you avoid mistakes and keeps your inventory accurate.

Tip: If you scan the wrong item, just tap “Remove” or “Void” to fix it fast.

Many beginners make small errors here. You might enter the wrong quantity or forget to scan an item. These mistakes can slow down the line and mess up your inventory. Here are some common errors to watch out for:

• Not enough training, which leads to slow checkouts and order entry mistakes.
• Only using basic POS features and missing out on tools that save time.
• Poor inventory tracking, which can cause you to run out of stock or over-order.
• Skipping regular updates, which can make your system slow or unsafe.
• Weak security, like using easy passwords or not setting user permissions.

Confirm Total

Once you add all the items, check the total on the screen. The pos machine pos terminal machine will show the subtotal, taxes, and any discounts. Ask the customer if everything looks right. This is your chance to fix mistakes before you take payment.

You can also apply coupons or loyalty points at this stage. If the customer has a membership or discount code, enter it now. The system will update the total automatically.

Note: Always confirm the total with the customer. This builds trust and helps avoid problems later.

Accept Payment

Now you’re ready to take payment. Most customers pay with a card, but some still use cash or mobile wallets. Tap the “Pay” button on the screen. Choose the payment type the customer wants.

• For cards, insert, swipe, or tap the card on the reader.
• For cash, enter the amount given and the system will show the change.
• For mobile payments, ask the customer to hold their phone near the reader.

If the payment goes through, you’ll see a confirmation on the screen. Sometimes, you might run into hardware or software errors. For example, the printer might not work, or the touchscreen might freeze. If this happens, check the cables, clean the screen, or restart the device. Make sure your payment settings are correct so you don’t miss out on card sales.

A typical sales transaction takes about 36 seconds. If the customer has more items, it might take a bit longer. For example, a basket with four items usually takes around 52 seconds. Most of the time, the speed depends on how many items you scan and how quickly you and the customer interact.

Print or Send Receipt

After you finish the payment, you need to give the customer a receipt. Ask if they want a printed copy or a digital one sent to their email or phone. Many people now prefer digital receipts, but some still want paper.

Here’s what recent surveys show about customer preferences:

Younger customers often choose digital receipts, while older shoppers may still want a printed copy. Always offer both options if you can. If the printer does not work, check the paper roll or restart the printer. If you send a digital receipt, make sure you enter the correct email or phone number.

Tip: Offering digital receipts saves paper and makes customers happy. It also helps you keep records organized.

Payment Types

When you use a POS cashier machine, you can accept many types of payments. This makes shopping easier for your customers and helps you make more sales. Let’s look at the most common payment types you’ll see at the register.

Card Payments

Card payments are the most popular way people pay in stores today. You’ll see customers use both credit and debit cards. In fact, about 40% of in-store transactions use credit cards, and these cards account for nearly three-quarters of all retail sales dollars. People like cards because they are fast and accurate. You just insert, swipe, or tap the card on your POS terminal.

Tip: Always check your card reader for any signs of tampering before you start your shift.

To keep card payments safe, you should:

1. Inspect your POS terminals daily for anything unusual.
2. Change default passwords right after setup.
3. Use strong encryption to protect cardholder data.
4. Update your POS software and hardware often.
5. Only let trained staff access the POS system.

These steps help protect your store and your customers from fraud.

Cash Payments

Cash is simple and easy to use. Some customers still prefer it, especially for small purchases. Right now, cash makes up about 16% of retail transactions in North America, but this number is slowly dropping. Most people spend less when they pay with cash—the average cash sale at a POS machine is about $22.

You just enter the amount given, and the POS system tells you how much change to give back. Always count the cash in front of the customer to avoid mistakes.

Note: Cash is still important, even as more people use cards and phones to pay.

Mobile Payments

Mobile payments are growing fast, especially with younger shoppers. Customers can pay using their smartphones or smartwatches. They just tap their device on your POS terminal using apps like Apple Pay or Google Pay. Many POS systems now work with platforms such as Square, Clover, PayPal Zettle, and Shopify. These tools make it easy to accept contactless payments and manage your sales.

Mobile payments are quick and secure. They also help you serve customers who don’t want to carry cash or cards.

Offering more payment options makes your store a favorite for more shoppers!

Returns

Access Transaction History

When a customer wants to return an item, you need to find the original sale first. Your POS system keeps a record of every transaction. You can look up sales by date, receipt number, or even the customer’s name. Most POS dashboards have a “Sales History” or “Transactions” button. Tap it to see a list of recent sales.

If you remember the date or time of the sale, scroll to that day. Some systems let you search by scanning the receipt’s barcode. If the customer lost their receipt, you can still search by their payment card or name if they used a loyalty account.

Tip: Always double-check the details before you start a return. This helps you avoid refunding the wrong sale.

Process Refund

You can process refunds in a few different ways, depending on your POS system and the situation. Here’s a simple step-by-step guide you can follow for most POS cashier machines:

1. Enable Refunds: Make sure your POS terminal has refunds turned on in the settings.
2. Find the Sale: Go to your transaction history and select the sale you want to refund.
3. Select Items: Choose the items the customer wants to return. Some systems let you restock these items automatically.
4. Start the Refund: Tap the refund or return button. The POS will ask you to pick the original payment method, like cash, card, or mobile wallet.
5. Complete the Refund: For card payments, the customer may need to present their card. Some cards allow refunds without the card present. For cash, just hand back the money.
6. Print or Send Receipt: The POS will print a refund receipt or let you send it by email or text.

If the customer does not have a receipt, some POS systems let you process an “unreferenced refund.” You start a new refund, enter the amount, and choose the payment method. Some stores offer refunds to gift cards if the original payment method is not available.

Note: Always follow your store’s refund policy. Some refunds may need a manager’s approval or have limits on the amount.

Refunds help keep your customers happy and show that your store is trustworthy. With practice, you’ll handle returns quickly and with confidence.

End of Day

Close Register

When your shift ends, you need to close the register. This step keeps your records accurate and helps you avoid mistakes. Start by finding the “Close Register” or “Close the Day” option in your POS menu. The system will guide you through each step.

• Count all the cash in your drawer, including coins and bills.
• Enter the total amount into the POS.
• The system will show you the expected amount. If there’s a difference, double-check your math and receipts.
• Enter the opening cash amount you want to leave for the next shift.
• The POS will calculate how much cash you need to remove and deposit.
• Add any notes if you need to explain a difference.
• Confirm and finish the close-out.

Tip: Always close out your register at the end of each day. This keeps your cash balances right and makes future audits easier.

Run Reports

After you close the register, it’s time to run your end-of-day reports. These reports help you see how your day went and spot any problems.

Here are some common reports you might use:

1. POS Z Report (Close Report): Shows total sales, payment types, refunds, discounts, and taxes.
2. Daily Summary Report: Gives a quick look at sales by product and payment type.
3. Detailed Product Sales Report: Breaks down sales by each item.
4. Gift Card Sales Report: Tracks gift card activity.
5. Invoices Report: Lists all invoices and payment status.

You can print these reports or save them for your records. Some POS systems even send reports to your email automatically.

Note: Reviewing your reports daily helps you catch mistakes early and keeps your business running smoothly.

Secure Cash

Now you need to handle the cash safely. Always follow your store’s cash handling rules. Use a two-person team to count the cash for extra accuracy. Compare your counted cash with the POS report and write down any differences.

• Place the cash in a tamper-evident bag or envelope.
• Store the cash in a safe or vault that only trusted staff can access.
• Both you and a supervisor should sign off on the final cash balance.
• If you notice any problems, tell your manager right away.

🚨 Always stay alert when handling cash. Secure cash drops and good records help protect you and your store from loss.
