How to run a café POS on a phone

What you need

• A phone with a recent version of Chrome, Edge, Firefox or Safari.
• An internet connection, and a mobile hotspot as backup.
• Your menu: categories, item names and prices.
• An email address you can open on the phone.

Steps

1. 1

   Sign up and confirm your email

   Go to kalasos.com/signup and create your venue. KalasOS sends a confirmation link to your email; open it, and your venue site goes live on its own subdomain, such as yourcafe.kalasos.com.

2. 2

   Add your menu

   In the admin, open Categories and add your sections, such as Coffee and Bakery. Then open Menu and add each item with its price, or choose Import CSV to add many items at once.

3. 3

   Turn on counter service

   Open POS Settings and turn on Counter service under Order Processing. Every order becomes its own check with no table, which suits a café where guests order and pay at the counter.

4. 4

   Optional: take payment first

   Under Payment Timing, turn on "Require payment for Takeaway orders" so takeaway orders are paid before preparation starts. For dine-in, the matching setting is "Require payment before order enters kitchen (Dine-In)". Payments are recorded as cash, your venue's static QR, or a split of both; KalasOS does not process them.

5. 5

   Open the Cashier screen

   On the phone, log in and choose Cashier on the home screen, or open /cashier on your venue's subdomain. Take orders and record payments there. If you have a second device, open your venue's subdomain on it as a kiosk for guests, or log in and choose Kitchen to use it as a kitchen display.

6. 6

   Print only if you need to

   A printer is optional. Bills and kitchen tickets open as PDFs sized for 80 mm or 58 mm paper: set Paper width in POS Settings and print from the browser's print dialog. There is no cash drawer or direct thermal (ESC/POS) printing, and Devanagari text prints as "?".
