ONDA Plus vs Enterprise
Enterprise CRS for Hotel Chains
One CRS to run reservations, rates, and inventory across every property — with real-time two-way sync to Oracle OPERA PMS.
One data model for inventory, rates & reservations
Inventory, rates, and reservations on a single data model
- Single data model — Inventory, rates, reservations, rooms, and profiles live as one source; OPERA, CMS, and the booking engine all read the same data
- Unified reservations — Create, edit, and multi-criteria search reservations from every path — PMS, OTA, your own website — in one place
- Rate & inventory control — Manage rate codes, availability, and cancellation rules alongside date-level room-type inventory
Multi-channel OTA integration via CMS
Run global and local OTAs from one window through the channel manager
- Multi-channel connectivity — Run dozens of OTA channels — Booking.com, Expedia, Agoda and more — through the CMS (channel manager)
- Channel profile mapping — Map each OTA channel's profile to OPERA so every reservation is attributed correctly
- Transmission status — Track OTA reservation status (success, failure, pending resend, processing) and resend failures on demand
OPERA sync (OXI standard)
Real-time sync with Oracle OPERA over the OXI standard protocol
- Two-way real-time sync — Reservations, rates, and profiles sync both ways; inventory mirrors in real time against the OPERA master
- OXI standard protocol — Sync over the OPERA Exchange Interface, with duplicate messages blocked automatically
- Zero-downtime, future-ready — Deploy on top of your existing OPERA; the same adapter carries you straight to OHIP (Opera Cloud)
Booking engine (direct sales on your site)
Run your hotel's own-website direct channel inside the CRS
- Direct channel — Reservations from your own website flow instantly into the CRS and on to OPERA
- Content & products — Manage room content, packages, display order, and cancellation rules
- External systems — Connect hotel CRM (membership, coupons, tiers) and PG payments to process on your own channel
Security, access & audit (ISMS-ready)
ISMS security policy built in from day one
- Multi-factor auth — Employee ID, password, assigned property, and OTP, with security-token session management
- Granular permissions — Per-page actions (view, create, edit, export, delete) mapped to roles
- Privacy & audit — AES encryption and screen masking, with change, access, and download history logged automatically
Multi-property operations
Run many properties centrally from a single system
- One instance, many properties — Run every property on one CRS instance with strict per-property data isolation
- HQ central management — Drive inventory, rates, reservations, and content for all properties from a single HQ dashboard
- Permission-based access — Reach one property or many by role; data outside your permissions is blocked automatically
Proven in production
Live at a Korean five-star hotel chain
- Operating scale — Direct-run and managed properties unified on a single CRS, running stably since launch
- OPERA two-way live sync — Direct-run properties sync reservations, rates, and profiles in real time, both ways, with OPERA PMS over the OXI standard
- Booking engine + membership — A proven build wiring hotel CRM (membership, coupons, vouchers, tiers) and PG payments into the own-website booking engine as a direct channel
- Security review — ISMS review passed, with a hardened permission model

The real admin screens of ONDA Enterprise CRS — inventory, rates, and reservations on a single data model.
Screens are demo / masked examples and may differ from live data.
Build your hotel's own channel manager on the ONDA Connectivity API.
With the ONDA Connectivity API, anyone can build their own channel manager — no separate OTA contracts required. Tap directly into the 75-channel infrastructure ONDA has built over 10 years through REST API, MCP, and Webhooks, and cut integration time down with standardized docs and SDKs.
Bidirectional integration
One integration, data flowing both ways between your PMS and ONDA — push content, rates, and inventory; receive reservations via webhooks.
Per-channel control
Set different prices, inventory, and open dates for the same room on every channel — all applied at once with a single API call.
You keep operational control
Your UX, your pricing, your sales policy — all stay with you. Only the channel infrastructure is abstracted into ONDA.
54,416 connected properties
The base layer of Korean supply. The moment your PMS lands on ONDA HUB, you're on the same infrastructure.
75 sales channels
Reach search engines, global OTAs, domestic OTAs, open markets, B2B corporate stores, and mobility — from a single line of API call.
10 years of proven operations
Battle-tested stability built on hundreds of channel contracts and hundreds of thousands of lines of integration code. Mutual confidentiality and SLA included.
