02Web applications
Booking engines, admin panels, portals and internal tools — software your customers and your team use every day, in any browser, with nothing to install.

What it solves
Five kinds of daily work a web application can do instead of people — and where each one is running live today.
Availability for the chosen dates, shown the moment they ask.
Ari Zona — free units for the chosen dates, live
The total for the whole stay and the prepayment, calculated on the spot.
Ari Zona — whole-stay total and 30% prepayment
Every booking gets a request number the guest can use to find it again.

What we build into it
Each application is scoped around one business. These are the building blocks we use most — your offer lists exactly which ones yours includes.
Example interface
Guests often search from a phone, on the road. The same booking engine answers there — dates, free units, the price and the way to book, all on one screen.
The search starts with what the guest already knows. One button — “Show free” — answers it.
The A-frame house, free: 3 600 ₴ for two nights, 1 080 ₴ prepayment — and an arrow straight into booking.
A fixed bar keeps both choices under the thumb, wherever the guest scrolls.
In the work
The booking engine behind a motel, and the admin panels behind three menus — software real businesses and their guests use daily.
Direct booking without intermediaries: live availability for the chosen dates, the price for the whole stay, a 30% prepayment, and bookings found again by request number. Website in Ukrainian and Hungarian, with a separate restaurant e-menu.
Don Corleone, Stare Misto and Sushi From Serg each run on their own admin panel: the owners change items and prices without calling a developer. The panels are private, so they aren’t shown here — the owners’ words are.
“Through the admin panel, we can update items and prices without needing to contact a developer every time.”
“A major advantage for us is being able to update the selection and prices ourselves through the admin panel.”

How the work goes
Five steps, the same for everything we build. You know what you get, for how much and when — before any work starts.
How projects are scoped and paidWe get to know your business and your goals. A short conversation shows what you need — and what you don’t.
A detailed offer and plan: exactly what you get, for how much, and when.
We design and build the system and keep you informed along the way — no black boxes.
We test on key screen sizes and modern browsers, fix what we find, and prepare the launch with your approval.
We launch, train you to manage it, and stay close afterwards — one message, and we help.
