! Why change the system at all
The money isn't lost on rates. It's lost on scattered data.
Bookings live in one place, guests write in another, payments are tracked by hand, and check-in depends on who happens to be around that day.

Talking to the guest
Two kinds of message — and neither wakes you up
Some messages the guest receives on their own. The rest you send when needed, from templates you wrote yourself.
Automatic · no click from you
The guest gets WhatsApp and email by itself
Twice, at exactly defined moments. You do nothing — the messages go out while you sleep.
1Right after booking — a confirmation with dates, amount, address and how to get into the building.
2Right after payment — the code for the apartment, with its exact validity window and a backup code.
✓In the guest's language, detected from their phone prefix. The same content goes to both WhatsApp and email.
Manual · your templates
You send template messages in one click
For everything else that gets agreed along the way. You write the templates; the variables fill themselves from the booking.
1You write the templates — confirmation, check-in, reminder, departure. As many as you need.
2You tap the WA button on the booking — the message opens filled in, you just send it.
✓Variables
{name} {apartment} {arrival} {amount} {door_code} resolve themselves.
▤ Mobile app
The whole property in your pocket — the part you'll use most
Most owners aren't sitting at a desk. That's why the mobile app is a product in its own right, not an add-on: everything you do during the day happens on the phone, in two taps.

A notification when it matters
A push arrives when a guest pays at the kiosk or a new booking comes in. Not for everything else.
◎ Guest app
The guest fills in their own details. You file them in one click.
The guest gets a link with their booking confirmation. On it they find everything they need for the stay — the WiFi password, house rules, FAQ and a PDF confirmation — and a form where they enter their own details for the guest register.
Once they send it, a completed registration is waiting in your app. One click and it goes to the register — with every field the law requires, for domestic and foreign guests. Checkout is filed on its own on departure day.
- No retyping passports at midnight and no handwritten lists
- Four languages — Serbian, English, German, Italian
- The guest fills it in whenever suits them, even before they set off
- You can see who has filled it in and who hasn't — before they arrive
§
Why does the guest type their details instead of scanning a document?
Because the law does not allow us to scan and store guests' identity documents. Technically we could fit a scanner into the kiosk without trouble — but the regulation rules it out. So we organised the system the other way round: the guest fills in their own details and sends them to you. It is both faster and legally clean.

Our story
We built Arriva because we needed it.
We run a small hotel ourselves. Every existing solution promised automation — none of them actually delivered it. If anything, they added new steps and new complications.
So we took matters into our own hands and built a system to the measure of a small hotel owner. Every feature runs in our own property first, and only then reaches you. If something annoys us, it never ships.
The result is a system that has exactly what the owner and the guest need — and nothing they don't.
“We wanted a hotel that runs itself.”
Founder of Arriva, hotel owner01Simplicity is a feature
Every surplus feature is a cost in your time.
02Built by users
We don't guess what owners need — we are owners.
03Being close matters
We answer in your language and, when needed, we come on site.
Common questions
Questions we get before the demo
What if a guest can't use the kiosk?
Check-in is four screens and asks only for a surname. If a guest gets stuck, your phone number is on the screen, and the app shows you that someone started a check-in and didn't finish — so you can check them in manually from your phone, wherever you are.
Is the kiosk mandatory?
No. The PMS, bookings, the guest app, messages and filing registrations all work without the device. The kiosk is for properties where self-service arrival genuinely pays off — usually those without a permanent front desk.
Why doesn't the kiosk scan identity documents?
Because the law does not allow us to scan and store guests' identity documents. Technically a scanner in the kiosk would be straightforward — but the regulation rules it out, so we organised the system differently: the guest fills in their own details in the guest app and sends them to you, and you forward them to the register in one click. It turns out to be faster than scanning, because the guest does it before they even arrive.
What does filing guest registrations look like?
The guest enters their own details in the guest app, in their own language and whenever it suits them. A completed registration is then waiting in your system, and one click files it — for domestic and foreign guests alike. Checkout is filed automatically on departure day.
Do I have to drop what I already use?
No. Booking.com and Airbnb stay your channels and keep working as before — Arriva connects to them. If you already have TTLock locks, we use those. If you have no smart locks at all, the kiosk still works: the guest gets the room's permanent code.
Who takes the cash out of the kiosk?
You do. The cash sits in a locked cassette inside the unit and comes out with a key. The app shows how much has been taken, by day and by booking, so the cassette and the records always match.
How long does setup take?
The software goes live the same day — we enter your rooms, connect your channels and bring across future bookings. The kiosk takes one site visit: we bring it assembled, plug it in and train you in half an hour.
Contact
Let's talk — owner to owner.
Leave a message and we'll come back with a demo slot tailored to your property. We show the system with your room count, your channels and your way of taking payment — no generic pitch.
- The demo takes 20 minutes and commits you to nothing
- The software goes live the same day, with your future bookings
- No lock-in contract — you stay while it pays off
