The QashierXL Slim is Qashier's full-sized POS: a 15.6-inch main screen for staff and a 10.1-inch customer-facing screen. It runs the full Qashier POS but cannot accept card payments on its own, so card payments run on a separate payment terminal. This guide gets a new XL Slim from the box to its first sale.
Applies to: Singapore, Malaysia, Philippines, Thailand · QashierXL Slim. If you have the original QashierXL (the label on the back reads "Newland CPOS X5"), use QashierXL POS Setup (original XL model) instead.
Before you start
A power socket near the counter and an internet connection: Wi-Fi or a LAN cable to your router.
Your QashierHQ login (email and password) to sign in to the POS.
A payment terminal, if you take card payments. In Singapore and Malaysia this is the QashierPay terminal supplied with your bundle; in Thailand, card payments run on a Beam terminal. In the Philippines, ask support which card terminal to use.
The receipt printer and cash drawer supplied with your bundle, if any.
Steps
Unbox and place the terminal. Stand it on the counter with the customer screen facing the customer. Keep the packaging until everything works.
Connect the cash drawer. Plug the drawer's telephone-style cable into the drawer port on the connector panel at the back of the terminal. If your main receipts print on a separate receipt printer, plug the drawer into that printer instead, because the POS then opens the drawer through the printer. To have the drawer open on every cash sale, tick Automatically open cash drawer when you accept a cash payment in QashierHQ; see How to Connect a Cash Drawer to Your Qashier POS.
Connect the power adapter to the power port at the back, then to the wall socket, and press the power button until the screen lights up.
Connect to the internet. Either plug a LAN cable into the LAN port, or on the welcome screen tap Connect to WiFi and choose your network. After you log in, Wi-Fi is under the ☰ menu > Wifi.
Log in to Qashier POS with your QashierHQ email and password. See How to Log in to Qashier POS. The POS downloads your products and settings; wait until the home screen shows your store name.
Set up receipt printing. If your XL Slim prints receipts itself, tap ☰ > Test in-built printer and check that a sample receipt comes out. If your bundle came with a separate receipt printer, set it up with How to Set Up the Qashier Wi-Fi Kitchen Printer or How to Set Up an Additional Printer via LAN (Ethernet) Cable, then tap ☰ > Test Print (Additional Printer) to check it. See How to Do a Test Print on Qashier POS (Built-in and Additional Printers).
Pair your payment terminal so card payments started on the XL Slim are completed on the terminal. In Singapore and Malaysia, see [SG/MY] How to Accept Card Payments on QashierXL with a QashierPay Terminal (QashierXS). In Thailand, pair a Beam terminal instead: see [TH] How to Pair a Beam Card Terminal (Bolt+) with Qashier POS.
Optional extras. Plug a USB barcode scanner into a USB port (connect a barcode scanner), and upload promotional images for the customer screen (How to Show Promotions on the Customer Display (Carousel)).
Make a test sale. Ring up an item, take it as cash, and check that the drawer opens and the receipt prints. Void the test sale afterwards from Transaction Record.
What you should see
The main screen shows the Qashier POS home page with your store name; the customer screen shows the order as you add items, or your carousel images when idle.
A cash sale prints a receipt and, with automatic opening turned on, opens the drawer.
A card sale sends the amount to the paired payment terminal and returns to the POS as approved.
