Case study — Tsarski · tsarski.rs
It started with a spreadsheet that stopped working
Tsarski is a booking system we built for an independent host running several venues without a front desk, a revenue manager, or an IT department — to replace the spreadsheets and group chats that were breaking down every peak season.
Two guests are booked into the same apartment on the same night. The cleaning crew never got the WhatsApp message about a same-day turnover. A tax receipt gets reconstructed from memory two months later.
A booking is checked against every other reservation at that venue the moment it's entered. The guest gets a confirmation email in their own language. The cleaning company sees the turnover on their own dashboard — no group chat required.
We didn't build a feature backlog. We built the tool the client needed to run their venues without a front desk.
The problem
Built for hotels, not for the person who owns one apartment
If you run a guesthouse or a handful of short-stay apartments, you're almost certainly managing it with tools that were never built for the job:
- Spreadsheets don't stop a double-booking — the first anyone hears about it is the guest standing at the door.
- Group chats don't guarantee the message landed — a cleaning crew finds out a room is turning over when the next guest is already checking in.
- Receipts get reconstructed from memory — city tourist tax and VAT worked out after the fact, not at the moment of booking.
- Enterprise property-management systems don't fit — they're priced and designed for hotels with a front desk, not one person running one to five units.
So we built something as fast to start using as a spreadsheet, that never double-books a room, never forgets to email a guest, and never loses a receipt.
What's inside
A day with Tsarski
Every chapter below came from a real gap in how the client was running their venues before Tsarski.
A calendar that can't double-book
Every venue on one calendar. Add a guest in seconds and Tsarski checks the booking against every other reservation at that venue — two guests can never land in the same room on the same night.
Guest communication that sends itself
Booking confirmations, pre-arrival reminders, payment-pending nudges, cancellation notices, and receipts go out automatically in English or Serbian, using an email template you control per venue.
A lightweight CRM for every guest
Contact details, stay history, and private notes sit under each guest's profile, with one-click resend of any past email or receipt — ready the next time they book.
One login, every venue
Add a new guesthouse or apartment without opening a new account — one owner login covers every property you run.
A portal for the people who clean your rooms
Your cleaning and maintenance crew log in with a one-click magic link — no password to manage — and see only the check-ins and check-outs across the venues you've assigned them, with their own earnings and payment slips tracked automatically.
Tax compliance built into the booking, not bolted on
City tourist tax, VAT, and guest ID (JMBG) are fields on every booking record, so every receipt is compliant the moment it's generated — no reconstruction from memory.
Why this fits
Depth for the smallest operators, not the largest
Built for one person, not a front desk
Every workflow assumes an owner running their own venue, not hotel staff — a focus that's hard for hotel-grade systems to retrofit without stripping features down.
A two-sided network through the agency portal
Cleaning and maintenance companies get their own free dashboard across every owner who's assigned them — an agency serving several properties has a reason to want all of its clients on Tsarski.
Compliance as a feature, not an afterthought
City tax, VAT, and national ID fields are part of the core booking record — a real switching cost once an owner's receipts and tax history live in Tsarski.
No setup fee, no long-term contract
The first 10 bookings are free with no card required; Premium is a flat monthly subscription per venue after that.
Tsarski is live today, with the full owner lifecycle running: self-signup, multi-venue management, the agency portal, and Serbian tax-compliant receipts.
