The POS screen

The POS (Point of Sale) screen is your checkout counter. It's where you add products to a basket, take the customer's money, give change and print their receipt — all in a few seconds.

Who uses itCashiers and shop staff, every day.

How long it takesA typical sale takes under 30 seconds.

Where to find itClick POS in the sidebar, or open /cashier.

Overview

When you open the POS screen, you'll see your products on the right (as tappable tiles) and the current customer's basket — called the cart — on the left. You add items to the cart, the system adds up the total including tax, the customer pays, and you're done. A receipt prints automatically if you have a printer connected.

The screen is built to be fast. You can run an entire sale using just a barcode scanner and the cash drawer — no mouse needed.

Why it's useful

It's quick. Scan-to-cart is near-instant, so queues move fast even at busy times.
It does the maths for you. Totals, tax and change are calculated automatically — no mental arithmetic, no mistakes.
It keeps records. Every sale is saved, so your reports, stock counts and customer balances stay accurate without extra work.
It works offline. If your internet drops, you can keep selling — see Selling offline.

How to make a sale, step by step

Open the POS screen
Click POS in the left sidebar. If your shop uses shifts, you may be asked to open a shift and enter your starting cash first.
Add products to the cart
There are three ways to add an item, use whichever is fastest:
- Scan its barcode with a barcode scanner — it drops into the cart instantly.
- Tap the product tile on the right.
- Type a name or code in the search box at the top and pick from the list.
Adjust quantities if needed
In the cart, use the + and − buttons to change how many of an item the customer is buying, or type the number directly. To remove a line, click the small × next to it.
Add a customer (optional)
If the customer has an account or wants to buy on credit, click Add customer and search for them. This is required for credit sales. See Customers.
Apply a discount (optional)
You can reduce the price of a single line or the whole basket. See Discounts & pricing for the details.
Take the payment
Click the big Pay button. Choose how the customer is paying — cash, card, or a mix. For cash, type the amount handed over and the screen shows the change to give. You can split one sale across several payment types. See Taking payments.
Finish & print the receipt
Confirm the payment. The sale is saved, the cash drawer pops open (if connected), and the receipt prints. The cart clears, ready for the next customer.

That's a complete sale

Most sales are just scan → Pay → done. Everything else on this page is for the less common situations.

Other things you can do here

Hold a sale and come back to it

If a customer forgets their wallet or needs to grab one more item, you don't have to cancel. Click Hold to park the basket safely, serve the next person, then reopen the held sale to finish it.

Weighed items

For products sold by weight (like fruit or loose grains), the system asks for the weight or reads it from a scale barcode. See Weighed & scale items.

Refunds from the counter

To give money back for a previous sale, open the ⋯ More menu and choose Refund / Return, then look up the original receipt. Full details on the Returns & refunds page.

Tips & best practices

Let the scanner do the work. A barcode scanner is far faster and more accurate than tapping tiles. It types the code for you — no setup needed.
Keep the cash you actually take honest. When paying by cash, type the real amount the customer hands you so the change and your end-of-day count are correct.
Use Hold instead of cancelling. It keeps the queue moving and avoids re-scanning everything.
Add the customer before paying if it's a credit sale — you can't switch a finished cash sale to credit afterwards.

Notes & warnings

A walk-in (no customer) sale must be fully paid before you can finish it. Only sales attached to a saved customer can be left partly unpaid (on credit).

Check the change on screen before opening the drawer in your head. The displayed change amount is always correct — trust it over manual calculation.

A completed sale can't simply be deleted. If you made a mistake, you either refund it or void it (while the shift is still open). This is deliberate — it keeps your money records trustworthy.
