Restaurant app & POS

Atelje Club 2026 In development

An app for the guest and a POS for the staff. Two systems already built, and the first steps of the ecosystem that will join them.

The start of one ecosystem for a restaurant with three locations in Bihać: an app and loyalty programme for guests, and a POS for the kiosk, kitchen, bar and waiters. Both are built; connecting them is the work in progress.

What we delivered

  • Customer app for iOS and Android, with loyalty and ordering
  • POS with self-service kiosk, kitchen and bar screens and a waiter app
  • A management panel for the app, and the link between the two systems in progress

The start of an ecosystem

Two systems built. One ecosystem in the making.

This ecosystem is still being built. What exists today are two systems, one facing the guest and one facing the staff. Joining them is the next stage.

Built

For the guest

Everything a guest does from their own phone, and the panel that runs it.

  • App for iOS and Android
  • Ordering and card payment
  • Points, tiers and rewards
  • Management panel
Built

For the staff

Everything that happens in the restaurant, from the order to the finished plate.

  • Self-service kiosk
  • Kitchen and bar screens
  • Waiter app
  • Receipt printer

For the guest

An app that gives guests a reason to come back.

Guests browse the menu, order for pickup or delivery from one of the three locations, and collect points for what they spend.

  • Ordering – pickup or delivery from Harmani, Prekounje or Centar, with extras and a note on every item.
  • Card payment – paid in the app through Monri, or in cash.
  • Points and tiers – a point for every KM spent, and four tiers from Bronze to Platinum.
  • Rewards – a rewards shop, a leaderboard and a personal QR code.
  • Promotions – fourteen kinds, from happy hour and buy-one-get-one to birthday gifts and spins.
  • Notifications – push messages to guests, sent from the management panel.

For the staff

One order, and everyone in the restaurant sees their part.

An order can start at the kiosk, with a waiter or at the bar. From there the kitchen sees the food, the bar sees the drinks, and each confirms its own side.

  1. Order placed Kiosk, waiter or bar
  2. Kitchen Sees the food
  3. Bar Sees the drinks
  4. Waiter alerted On the phone, when ready
  5. Closed Charged at the bar

A self-service kiosk that walks the guest through the order

Guests order on a large upright touch screen, built for a finger rather than a mouse. These are its real screens, one step at a time.

A phone in the waiter's hand

Waiters pick the table on a floor plan of the location, then build the order with the same options as the kiosk.

  • Kitchen screen

    Each order as a large card with a timer and the guest's notes. One press marks it done.

  • Bar screen

    Drinks, tables and takeaway in one view. A sound marks each new kiosk order.

  • Waiter app

    An Android app with the tables of each location. It vibrates and shows a message when an order is ready.

  • Recipes and stock

    Each item is built from its options and ingredients, with extra charges where they apply and stock entry from the kitchen.

  • Ready-made items

    Items prepared in advance are marked as ready, so an order made up of them skips the kitchen.

  • Display schedule

    The kiosk computer can be switched on and off from the settings, or by itself on a schedule.

Screens are the real apps and POS, shown here in English. Orders, the guest account and the leaderboard are samples, and the kiosk unit in the picture is an illustration.

What comes next

Where the ecosystem goes from here.

These steps are not finished yet. Each one joins something the guest does to something the staff do.

  1. 01

    Points at the kiosk

    A guest shows the QR code from the app at the kiosk, and the purchase counts towards their points.

    Already prepared: the member QR code, and the connection for the kiosk on the app side.

  2. 02

    App orders on the kitchen and bar screens

    An order placed on a phone appears on the same screens as an order from the kiosk or a waiter.

    Already prepared: order statuses in the app, and live kitchen and bar screens in the POS.

  3. 03

    One menu behind everything

    The app and the POS work from one menu and one set of prices, instead of keeping their own.

    Already prepared: the full menu with options and ingredients in the POS.

01 Business context

Atelje Club is a restaurant with three locations in Bihać: Harmani, Prekounje and Centar. This work is the start of one ecosystem around it, connecting the guest, the kitchen, the bar and the waiters.

A guest can order at a self-service kiosk, from a waiter, at the bar or from a phone. Each of those has to reach the right people, with the right notes, while the place is full.

So the work started with two systems: an app and loyalty programme for the guest, and a POS for the staff. Both are built, and joining them is the stage now under way.

01 Coupons and the guest's tier, and a rewards shop where points turn into items.

02 The challenge

A restaurant takes orders from several directions at once, and each of them has to reach the right people.

  1. 01 Orders coming from a kiosk, from waiters and from the bar, all at the same time
  2. 02 Food and drinks in one order, prepared in two different places
  3. 03 Waiters who need to know the moment an order is ready
  4. 04 Guests who need a reason to come back

03 The solution

Two systems, each built for the people who use it, with the link between them as the next stage.

The POS gives each place its own screen: an upright touch screen for guests, large cards for the kitchen, a full view for the bar and a phone for the waiter.

The app gives guests a menu, ordering and card payment, along with points, tiers, rewards and promotions run from a management panel.

The connection is prepared on the app side, with a member QR code and points for kiosk purchases. It is not yet in use by the POS.

02 The kitchen screen: each order as a large card with a timer and the guest's notes. The orders shown are samples.

04 Key capabilities

What it makes possible.

  1. 01

    Orders that reach the right screen

    Food goes to the kitchen and drinks to the bar, with the guest's extras and notes on them. Each side confirms its own part, and the waiter is told when it is ready.

  2. 02

    A kiosk guests can use on their own

    Large photos, large prices and a basket that is always on screen. The guest chooses eating in or taking away, and a slip comes out with the order number.

  3. 03

    Items built from real ingredients

    Each item is made up of options and ingredients, so extras, charges and what goes into a sandwich are set once, in one place.

  4. 04

    A reason to come back

    Points on every order, four membership tiers from Bronze to Platinum, a rewards shop, a leaderboard and a member QR code, all in the guest's own app.

  5. 05

    Promotions the business runs itself

    Fourteen kinds of promotion, from happy hours and buy-one-get-one to points multipliers, each limited by tier, period or voucher code, and messages sent straight to guests.

  6. 06

    Built to grow into one ecosystem

    The member QR code and the kiosk connection already exist on the app side, ready for the next stage of joining the guest and the restaurant.

05 Business value

What changes for the business.

  • Each order goes to the people who have to act on it, on a screen made for where they stand.
  • Guests have their own app, with a loyalty programme the business runs itself.
  • Both sides are built to be joined, so the ecosystem can grow one step at a time.

The start of one ecosystem: the guest on a phone, and the kitchen, bar and waiters on their own screens.
