Download the app
App can be found on App store for iPhone as “Kustom point of sale” - easily download it from there. Make sure you have updated your iPhone to the latest version as Tap to Pay may require it.
App onboarding & setup
First time you open the app you will be guided through a short setup tutorial with the main steps to make you purchase ready:
Select a merchant
Enable & pick a Location
Select and open a cash register
Enable a Reader connection with Tap to pay
Quick connect
If you are trying to make a purchase but haven't got a cash register open or a Reader connection established, with tap to pay or a terminal, then we will prompt you when starting the payment to quickly make you purchase ready. Open the cash register with the drawer and click the Reader connection to get a green light on both and proceed.
Note: You need to have passcode or FaceID enabled on your iPhone per apple security policy requirements to use Tap to pay. Terminal connection is made for customers using physical terminals that are in closed pilot for selected SE merchants.
Open your cash register
A cash register needs to be open to start transacting you can open the cash register from the settings. Only one user and device can operate a cash register at a time. If you need to switch, close the current cash register that another user is operating and open it again to claim it.
Take purchases (Tap to Pay)
If you haven't configured your own products and catalog yet then you will see a Test Product in the MPOS app that you can use to try out the purchase flow.
Build a cart from the Sale menu by pressing the products from your catalog and proceed to payment by pressing the cart symbol or Payment button. Alternatively use the Barcode scanning feature to scan products and build the cart.
On the payment screen, select Tap to Pay on iPhone. Then allow the shopper to tap their card or wallet on your screen.
Add discounts on the cart screen at the item level or for the entire cart by entering a percentage or amount to be discounted.
Once payment is confirmed, send a digital receipt to the shopper's email—either by having them scan the QR code or by manually entering their email address using the "Send receipt" button.
MPOS orders with Tap to pay will be auto-captured by Kustom
Note: NFC reader sits on the top of your phone so have shoppers tap there to successfully complete the payment. Tap to pay also supports transactions that require PIN - this will trigger automatically when required.
Free amount
If you don't have a product catalog uploaded or have a need to customize the sale quickly we do support a free amount option in the app, similar to a standalone terminal.
Press the free amount button on the Sale page
Input the sale amount
Add a description to the sale if needed, this will be displayed on the receipt and in the reporting. By default these sales are tagged with the product name "General Goods and Services" if you don't input a description
Add a MOMS (VAT) rate, by default 25% is selected.
Note: If you need reliable reporting and SKU reconciliation we recommend to upload a product catalog and not use the free amount.
Scan to pay
As a second payment method we also offer Scan to pay which is a QR-code based payment flow where shoppers can select Klarna and Swish as payment methods
After the cart is built or you have entered the payment amount you press "Scan to pay" button on the payment screen
This triggers a QR code on your device that the shopper can scan where they get to our hosted payment page and form
Here they can select their intended payment method and complete the purchase on their own phone
At the end of the flow they will be shown a receipt that they can download as a printed PDF or send to their email
On your MPOS app you will see the success screen and can trigger a receipt from there as well if needed.
Barcode scanning
You can now also use the iOS devices camera to scan items to build the cart. If you have added EAN code correctly on the products then this will be scanned and appropriately populated in the cart with the correct product. If you haven't added the product yet then we offer the option automatically to quick add the product with the scanned EAN code.
Press the Barcode symbol on the Sale page in the app on the lower left part of the screen to trigger Barcode scanning.
Quick add products
If you need to quickly add several products and items to the cart then use the quick add products:
Go the cart page from the Sale menu on the top right corner
Press the + symbol and input the product data
Add one or several items
Press the Payment button
Refunds & returns
Go to the Orders view in the app
Shoppers can supply their Order reference or Receipt number for you to identify the order to refund
Click and select the Order you want to refund from the list
Press Refund - the refund will be processed instantly to the same payment method (card) that the shopper used to do the payin
You can then click on the refund order & transaction from the same view to issue a Refund receipt if requested
Refunds will show as negative amounts in the Orders view
Refunds for MPOS orders can also be done via the normal Portal interface but we recommend doing them from the app, if the return has happened in store, due to the refund then being logged in the cash register as per Cash register regulation.
Note: Only MPOS orders and transactions will show here, eCom/online orders can be seen in the portal on the Orders tab. Only full refunds are supported today in the MPOS app.
Close the cash register
You can close the cash register in the app settings. This generates an end-of-day report (Z-report)—a summary of all transactions and receipts from when the cash register was opened until it was closed. Make sure to close your cash registers at the end of each sales day when you close shop.
