An international platform for automated reservations and global hotel distribution.
HotelOne Sync is an international hotel distribution and reservation system built from proven technology by partners in three Balkan countries. From Bulgaria - HotelOne. From Greece - BookOnlineNow, a booking engine with 3,000+ hotels in 65+ countries, and HotelAvailabilities, a channel manager active in 7 international markets. From Turkey - SAN Sejour, one of the leading software solutions for Destination Management Companies (DMCs) in the region, with 600+ active partners in 70+ countries.
Together we solve one of the hotel industry's long-standing challenges: one tool for reservations, rates and availability that manages every channel and segment at the same time - direct sales through the website and social media, corporate contracts, DMC contracts, tour operators, GDS distribution, online wholesalers, OTAs and meta search. All from one command center.
Rule-based and grid-based rates.
For the first time together, under one control.
Most hotel rate systems support only one of the two approaches, or combine them with difficulty. Rule-based rates serve DMCs and tour operators - prices are calculated from contracts with rules. Grid-based rates serve OTAs and online wholesalers - prices are set in a date matrix. Sync supports both approaches at once and unites them in a single structure that links rooms, meal plans and rates. The result is orderly, controlled distribution for every segment.
Links between rooms, meal plans and rates
Room pools - two mechanisms
Rates tailored to every partner
Automated daily operations
A modern Booking Engine + 12 tools
A Booking Engine with a refreshed interface for 2026, complemented by 12 tools that turn it into an effective sales channel rather than just a booking form. Every step of the guest journey - from discovering the hotel and comparing it with OTAs to payment and the return visit through the loyalty programme - is under your control. B2B, corporate and offline requests are handled with the same logic.
Partners get fast, natural communication
Standard channel managers treat all partners the same - and that is exactly where they lose business. DMCs and tour operators require far more logic and nuance than online channels. If automation ignores this and treats them like OTAs, the hotel loses partners and revenue. Sync is built so that communication with the partner is fast and natural, just like working with a staff member. The system follows your settings and automates what you choose, while the decisions that should stay with you, stay with you.
From contract to Folio, automatically
Every charge automatically reaches the right account (Folio). Guarantees, cancellations and payments are handled by a single structure that defines who pays what, which penalty applies and which account each item goes to - guest, corporate, group, partner or OTA collect. The front office doesn't calculate anything by hand, and the finance team doesn't chase missed charges.
A Central Reservation Office with AI
Hotel chains have traditionally relied on an external Central Reservation Office - a team that takes requests and turns them into bookings. Sync includes a built-in Central Reservation AI. It works across email, phone, social media and messaging apps, in many languages. It recognises when it can close a conversation on its own and when to hand it over to a staff member. It works 24/7 and improves over time.

Most of the business volume is handled through structured integrations - Channel Manager, H2S protocol and Direct API. The AI Email Agent serves partners that don't yet support a direct connection, regardless of their size. A large tour operator that works by email is not a “small partner” - it is a partner that doesn't offer an API yet. Sync processes its reservations automatically until a direct integration becomes possible.
A balanced business mix. Realistic expectations.
Sync doesn't promise unrealistic results. It makes each of your channels more efficient and automated, works 24/7 and allows a clear comparison of profitability between segments.
DMCs and tour operators are partners, not competitors
Club Magellan, Go2Holiday, DTS, TUI, Jet2, Alltours and ITAKA solve problems an independent hotel would struggle to solve alone: they provide transport connections to the destination, offer ground services and build distribution networks in source markets. The direct channel cannot generate that kind of demand. We don't promise to turn their customers into direct bookings at a higher net rate - that is unrealistic and harms both the hotel and the whole destination. Sync serves these partners quickly, automatically and professionally. They bring more business, the destination grows, prices rise - and the hotel wins together with them, not against them.
Booking and Expedia won't become a direct channel
Booking Holdings and Expedia Group invested over $20 billion in marketing in 2025 alone. For Expedia that is 50% of revenue, for Booking - 30%. About half of Booking's marketing budget goes to Google. Some of the bookings you receive from Booking or Expedia come precisely because these platforms paid Google for them. The promise that these bookings can become direct for a 5% commission is unrealistic. We support direct sales with everything Sync offers, while keeping the balance between channels. Realities 03 and 04 explain why.
Direct sales require infrastructure
Direct sales take more than a Booking Engine: a marketing budget, meta search presence, an optimised brand.com and a CRM for returning guests. That's why the Sync Booking Engine is complemented by 12 tools covering all of these needs. They are optimised for the independent hotel and matched to real market conditions. The result is a healthy business mix that you can objectively compare with your other segments.
Balance matters more than focusing on one channel
Hotels rarely lose ground because they didn't focus entirely on direct sales. Far more often, the cause is unbalanced pricing between segments, which distorts the business mix. Sync gives you the tool to shift volume between OTAs, DMCs, tour operators, corporate, meta and the direct channel according to the real market situation - without breaking rate parity and segment allocation, and without risking the contracts that already work.
