ONDA is a hospitality tech company that connects accommodations to the digital world. For the 10 years since our founding in 2016, we have provided integrated solutions that help properties easily leverage online sales channels (OTAs) and AI-powered services.

From small pensions to large hotel chains, ONDA enables you to list your property on global sales channels and manage bookings through a single system.

We support almost every type of accommodation.

• Pensions and pool villas
• Guesthouses and hostels
• Motels and boutique hotels
• Business hotels and resorts
• Campgrounds and glamping
• Hotel chains

From a single room to several hundred — size doesn't matter.

Which product fits - ONDA Plus — Owner-operated properties like pensions, pool villas, guesthouses, and hostels - ONDA Enterprise — Properties above roughly 150 rooms, or chains and multi-property operations

For other types (motels, campgrounds, etc.) it depends on how you operate, so we'll walk you through the options in a consultation.

Yes. We currently provide services primarily in Korea and across Asia, and are continuously expanding. Through global OTA channel integration, your property can be exposed to travelers worldwide.

Please contact us if you'd like to use ONDA in other regions.

A channel manager is a tool that lets you manage multiple online sales platforms (OTAs) through a single system.

With ONDA's channel manager: - Manage inventory (rooms), pricing, and content (photos, descriptions) across channels from one place - Changes made in one place are automatically reflected across all connected channels - Phone or messenger bookings can be manually registered for unified management

No need to log into each channel separately—saving significant operational time.

A booking engine is a system that lets guests book directly with your property, bypassing OTAs.

Key Benefits: - Significantly lower commissions compared to OTAs - Automatically included in ONDA Plus free websites - Can be integrated into existing websites via widget or link - Automatically registered as official site on Google Hotels for guaranteed exposure - Property info also appears in AI searches (ChatGPT, Claude, etc.)

CRS (Central Reservation System) is a central reservation management system designed for hotel chains.

It enables headquarters to centrally manage inventory, pricing, and reservations across all properties, integrating with existing hotel systems like Opera.

Key Features: - Centralized inventory and pricing control across all properties - Bidirectional integration with existing PMS/CMS - Unified brand reservation management - Channel-specific distribution strategy settings

ONDA Plus is an all-in-one platform for owner-operated properties. Pensions, pool villas, guesthouses, and small hotels manage reservations, channels, and content in one system.

ONDA Enterprise is for hotel chains and properties with many rooms. On top of CRS, PMS, and the channel manager, it supports customization to fit your business.

ONDA Plus is a direct SaaS under the ONDA brand — operators run their property in our UI (3,287 active properties).

ONDA CMS API layers our channel infrastructure (75 channels) on top of your own PMS or reservation system. Enter the market with your own brand, UX, and pricing while ONDA handles the channel side.

Global channel managers excel at global OTA integration but have weak coverage of Korean channels (Goodchoice and other Korean OTAs, B2B corporate benefit sites).

ONDA has focused on the Korean market for 10 years and built 75 channels and inventory of 54,416 properties, with native Korean operational support.

→ For the Korean market, ONDA is the fastest path — global OTAs + Korean OTAs + Korean B2B in one integration.

Our first reference is the IT subsidiary of a Korean hotel chain, covering 150 directly operated hotels — a hybrid integration combining their own CMS with the ONDA Vendor API.

Additional cases will be published as they become available. After an NDA, we share anonymized cases in sales meetings — segment, property scale, challenges, and outcomes — in concrete detail.

It depends on how you operate.

• Agoda alone is enough → Basic Host (free, if you meet all three conditions)
• You also run global OTAs and care about value → Pro Host (most recommended)
• You want hands-on AM support plus MCP and the newest AI features → Expert Host
• Over 150 rooms, a chain or multi-property setup, or custom API/MCP integration with your own PMS → Enterprise

Not sure? Send us a note and we'll recommend a plan based on how you operate.

There are four plans. Prices are shown excluding tax.

• Annual billing is 20% cheaper
• No extra charge based on room count
• The core Pro and Expert features launch in Q1 2027. Sign up early and you pay nothing until launch, then 50% for the first six months.

→ See full pricing

No — all listed prices exclude tax. Applicable tax is added at checkout based on your market.

Rates differ by country: 10% VAT in Korea and Japan, 9% GST in Singapore, 7% VAT in Thailand, 5% in Taiwan and the UAE.

Tax invoices are issued monthly and can be downloaded from your partner dashboard.

→ See full pricing

Yes, Basic Host has no monthly fee. You just need to meet all three conditions below.

• Connect Agoda, our strategic partner
• Enable payments on your booking engine (direct bookings)
• Connect Google Hotels and Google Vacation Rental Official Site

We offer it free under these conditions so hosts running many online channels with a small team can try ONDA Plus, our next-generation channel manager, without any commitment.

No. Basic, Pro and Expert all have no per-room charges.

Up to around 150 rooms you pay the same monthly price no matter how many rooms you run. Above 150 rooms the operating setup changes, so we prepare a custom Enterprise quote.

Yes — annual billing is 20% cheaper. You pay for a little under ten months instead of twelve.

Toggle between monthly and annual on the pricing page to compare the actual amounts. Basic Host is free already, so it doesn't apply.

→ Compare monthly and annual

Korea is billed in Korean won (KRW); everywhere else is displayed and billed in US dollars (USD).

You can switch the currency yourself on the pricing page, and your choice is remembered on your next visit.

The amount that actually lands on your statement depends on your card issuer's exchange rate. If you need billing in a specific currency, let us know.

→ See pricing · Contact us

The core Pro and Expert features (AI OTA Auto-Reply, Legacy channels and more) go live in Q1 2027. Right now we're publishing pricing and taking Early Bird pre-registrations.

Basic Host is available today.

Billing starts after the official launch. From pre-registration until launch there is no charge at all.

Once the launch date is set we'll let you know before billing begins, so you can decide then whether to continue.

Pre-register before launch and you get two benefits.

• Free until the official launch
• 50% of list price for your first 6 months after launch (in Korea: Pro ₩45,000 · Expert ₩135,000, VAT excluded)

List price applies after 6 months, and we'll let you know before that happens.

There's almost no upfront burden.

• Setup fee — Free
• Contract commitment / penalties — None
• Monthly subscription — Basic Host stays free. Pro and Expert launch in Q1 2027, so if you sign up early you pay nothing until launch.

See the pricing page for the amount on each plan.

→ See ONDA Plus pricing

There are two, and they cover different things.

1. Monthly subscription — for using ONDA Plus A fixed monthly amount based on your plan. Basic Host is free.

2. Booking commission — only on bookings sold through channels Charged only on bookings sold under ONDA's delegated contracts, and deducted automatically at settlement. No bookings, no commission. The channel's own commission is already included, so you don't pay the channel separately.

3. Booking engine direct reservations Bookings taken on your own site carry a far lower commission than OTAs.

Rates vary by property type and channel mix, so we'll walk you through them in a consultation.

→ See pricing · Ask about commissions

No. The ONDA commission deducted during settlement includes the channel commission. You don't pay any separate fees to channels.

In other words, a single ONDA commission covers everything from channel listing to settlement.

The amount after deducting ONDA's commission is settled to your property.

Settlement Cycle: - Weekly: Monday–Sunday based on checkout date → Settled the following Friday

Tax Related: - Sales data for VAT filing can be downloaded in Excel (monthly / quarterly / semi-annually)

It depends on the channel.

• Delegated OTA bookings — Each channel's own cancellation and refund policy applies (Booking.com, Agoda, and so on).
• Booking engine direct reservations — You set the policy yourself.

The advantage of direct bookings is that you run the policy exactly the way you want.

Subscription refunds are a separate matter — see Can I get a refund if I cancel my subscription?.

Yes, at any time.

• Pro → Expert upgrades apply immediately and we only charge the difference
• Expert → Pro downgrades apply from your next billing cycle
• Moving down to Basic requires meeting the Basic activation conditions (channel and payment integrations) again

There is no cancellation penalty.

There's no cancellation penalty. Once you cancel, you won't be billed from the next cycle, and you keep access through the period you've already paid for.

Whether a partial refund applies to the period you've already paid depends on your payment method and how long you've been subscribed, so please contact us and we'll confirm your case.

What about your data? You can export reservations and settlement records to Excel from your partner dashboard at any time. We recommend downloading them before you cancel.

→ Ask about cancellation and refunds

Simple — 4 cost items.

• Monthly subscription — tiered by commitment length (large discount for long-term)
• One-time setup fee — per property, replaces MG/upfront
• Channel transaction fee — varies by channel type (general · Naver · Booking Engine · legacy)
• Optional channel integration fee — only for some paid channels

No MG/upfront / Significant discount for long-term contracts / Self-PG option (for large operations) / Negotiable back-margin

Exact pricing depends on your room count, commitment length, and channel mix — a 30-min consultation gets you a tailored quote.

Here's how it goes.

• Inquiry — Apply through the website or by phone (1544-3812)
• Documents — Send us the required documents by email
• Partner page setup — ONDA completes the initial setup and walks you through it by phone
• Channels go live — Start selling

Documents you'll need - Business registration certificate - Accommodation business license - A copy of your bank account - Photos (100KB or larger / JPG, JPEG, PNG / landscape) - Rate and settlement sheet

You don't sign up channel by channel — ONDA opens them all at once.

→ Apply now

Much faster than you'd expect!

Compared to registering with each channel individually (2–4 weeks per channel), ONDA lets you open on all channels simultaneously in a fraction of the time.

Yes, it's possible.

• Most channels proceed as new openings.
• Some channels like Naver, Kakao, and Goodchoice allow transferring existing information and reviews.

Transfer time depends on channel policies — as fast as 1 day, up to 10 business days. Once connected, you can manage all channels from a single system, making the initial investment highly efficient.

How much can move over depends on the type of data.

• Rooms, rates, and photos — ONDA sets these up from the materials you send at signup. You don't migrate them yourself.
• Channel listings and reviews — Some channels, including Naver, Kakao, and Goodchoice, can carry them over as-is.
• Existing reservations — This depends on how each channel is migrated. Typically, bookings confirmed before the switch stay on their original path, and you manage bookings from the switchover onward in ONDA.

Tell us which PMS you're on and roughly how many bookings you handle, and we'll confirm what can be moved.

→ Ask about data migration

Support depends on your plan.

• Basic — email and online inquiry support
• Pro — onboarding support included
• Expert — onboarding plus technical support
• Enterprise — a dedicated AM works with you from setup through daily operations

ONDA assigns a dedicated manager 1:1 when you sign up. We provide continuous support from initial setup to operational know-how.

Exact timeline depends on your PMS architecture and team. A 30-min consultation will give you a concrete estimate.

Yes, they are automatically blocked.

When a booking occurs on any channel, ONDA's system automatically deducts inventory across all connected channels within 2 seconds. The actual overbooking rate is 0.003%.

You can operate with confidence, free from overbooking worries.

No. Just make changes once in the ONDA partner page, and they're automatically synced across all connected channels.

Photo updates, room description edits, rate changes, inventory adjustments—just modify in one place and you're done.

Yes! With the ONDA Plus mobile app (iOS/Android), you can manage everything anytime, anywhere.

Key App Features: - Open / Block rooms - Booking confirmation and management - Rate setting and changes - Sales overview - Partner inquiries - AI Assistant (pricing advice, competitor comparison, etc.)

Yes, it's possible.

• Booking notification contacts: Up to 3 can be registered (receive notifications simultaneously)
• Partner page / Mobile app: Multiple users can access and use simultaneously

Convenient for family-run operations or when you have staff members.

When you sign up for ONDA Plus, we create a free SEO + AI(LLM) optimized responsive website for you.

Includes: - Built-in booking engine (direct booking system) - Mobile/PC responsive design - Search engine optimization (SEO) - AI search optimization (appears in ChatGPT, Claude, etc.)

The website can be launched immediately. Note that Google Hotels and Google Maps listing may take approximately 10 business days.

AI replies automatically to guest messages that come in through OTAs — handling messages, inquiries, and reviews on major channels like Booking.com, Agoda, Expedia, and Trip.com.

What it handles - Check-in and check-out time questions - Facility questions like parking, Wi-Fi, and breakfast - Arrival guidance and location questions - Thank-you messages for reviews

Scope differs by plan 1. Basic — Basic chat plus automatic booking confirmation messages 2. Pro — Adds conditional auto-reply message rules 3. Expert — Adds AI-powered replies to guest inquiries 4. Enterprise — Lets you design the response scenarios yourself

Fast responses are decisive for ranking in OTA visibility algorithms, so you keep your response rate up on weekends and overnight.

The Pro and Expert versions launch in Q1 2027.

The AI phone assistant is one of ONDA Plus's core modules, launching Korea-first in Q1 2027.

How it works - When a guest calls your property, ONDA's AI assistant answers in Korean or English - It quotes available rooms and rates, check-in times, and arrival guidance - It hands off to the booking engine when payment or confirmation is needed - It forwards to the operator's mobile when it can't answer

Why it helps - You don't lose booking opportunities outside business hours - Less burden handling foreign-language guests - Call transcripts and summaries are available in your partner dashboard

Included in the Pro and Expert plans. Other regions will follow in phases.

Yes, we already have integrated kiosk and smart door lock products.

For other products, please contact us with your room count and product information, and we'll let you know about integration availability.

→ Inquire about kiosk/door lock integration

For managed operations services, please contact us for detailed guidance. We'll propose the optimal solution based on your property's size and requirements.

→ Inquire about managed operations

Supported Package Types: - Breakfast included packages - Long-stay discount packages - Seasonal special packages - Facility access packages

Created packages can be sold through the booking engine (direct booking) and select OTA channels.

Yes, with Enterprise's multi-property dashboard, you can manage multiple locations in one place.

• Independent settings per brand / location
• Unified reports across all properties (revenue, bookings, occupancy)
• Centralized management of all inventory, pricing, and reservations

Maintain individual property autonomy while enabling unified headquarters-level operations.

ONDA has directly integrated 75 channels over 10 years. All of them are live, processing millions of bookings a year in real time.

What kind of channels - Global OTAs and metasearch — Booking.com, Agoda, Airbnb, Trip.com, Google Hotel, and more - Korean OTAs and e-commerce — Goodchoice, Naver, Coupang, Kakao, and more - Travel specialists and cross-sell, B2E corporate benefits marketplaces, regional tourism portals, pet/kids/leisure, MICE, associations and D2C

A single contract lists you on every channel at once, and we keep adding more. Korean OTAs, B2E, and regional tourism — the areas where global channel managers are weakest — are ONDA's 10-year operational moat.

Plus channels (ONDA HUB) are channels where ONDA has negotiated preferential rates and placement directly with the channel (Goodchoice, Naver, Agoda and more). Sign up and those terms apply automatically.

Legacy channels (OTA CM) are global OTAs such as Booking.com, Agoda, Expedia, Airbnb and Trip.com. ONDA doesn't negotiate separately here — you connect on the channel's own terms.

If a large share of your guests come from abroad, running Legacy channels too usually pays off, and that requires Pro Host or above. See the full comparison on the channel policy page.

Yes. Global OTAs like Booking.com and Expedia connect as Legacy channels, and your existing contracts and settlement terms stay exactly as they are. ONDA doesn't renegotiate with the channel on your behalf.

Legacy channel integration is available from Pro Host.

There are two ways your rooms get sold on a channel.

Delegated — Sold under the contract ONDA already holds with the channel. ONDA handles listing, settlement, and customer service, so you don't sign with the channel yourself. Settlement across channels arrives together in one payment.

Direct — Your own contract with the channel stays in force, and ONDA handles inventory and rate synchronization. Your existing terms are preserved, but settlement follows each channel's own cycle.

Which one works better depends on your channel mix and how much of your demand comes from overseas, so we'll walk you through it in a consultation.

→ See channel policy

By opening through ONDA, your property gets simultaneously listed on numerous Korean and international channels. This exposes your property to a much wider range of travelers compared to relying on a single channel.

While each channel's exposure algorithm follows its own policies, ONDA supports you with: - Content optimization: Guidance for improving photo and description quality - Price competitiveness analysis: Market price comparison through AI assistant - Response rate management: Quick booking confirmations to improve channel reputation

Additionally, through the booking engine, you get direct exposure on Google Hotels and AI searches.

Yes, ONDA provides a RESTful API.

What you can build with our API: - Property search and lookup - Real-time pricing / inventory check - Booking creation and management - Payment processing

API documentation and technical support are available at the ONDA Developer Center.

→ Go to Developer Center

MCP is a connection standard that lets AI work directly with ONDA's booking and inventory data, so AI agents and chatbots can handle accommodation bookings in natural language.

What that looks like - “Find a place for two near Gangnam, Seoul” - “Book a pension in Jeju this weekend” - “Compare Busan hotel prices for three nights”

Use it to build your own property management tooling, or to connect your internal AI to ONDA so it can look up and act on bookings and inventory. It's shaped for AI service development in a way a traditional REST API isn't.

On ONDA Plus it's available from Expert Host, launching in December 2026. Enterprise supports custom MCP.

→ See the Connectivity API

Yes. You can build a channel manager under your own brand and start operating officially integrated OTA channels right away.

We open the 75-channel sales infrastructure ONDA built over 10 years as a single standard API set. A hotel SaaS startup launching its own-brand channel manager in six weeks is a realistic scenario.

→ See the Connectivity API

API integration is ideal when you want to fully integrate ONDA's property data and booking features into your own service. ASP is suitable when you want to provide accommodation booking services without development.

It works over standard HTTP REST + JSON, so it's callable from any language or framework.

From the OpenAPI 3.1 spec, you can auto-generate client code in nearly any language — Java, TypeScript, Python, Go, etc. Auth is Bearer token, and webhooks are plain HTTP POST so the receiving side is implementation-free.

API docs: `vendor.dapi.tport.dev`

Today we issue a 1:1 sandbox account after an NDA, following a sales meeting.

We're also building a self-service path — sandbox, automatic API key issuance, and an interactive docs walkthrough. Until that's ready, 1:1 support from an ONDA PM gets you the same result.

→ Ask about sandbox access

ONDA guarantees 99.9% service uptime.

We maintain service stability through a 24-hour monitoring system and respond promptly to any incidents.

API traffic is protected with HTTPS and Bearer tokens. Data is processed in transit only and is not permanently stored at ONDA.

Webhooks run over standard HTTP POST, backed by 10 years of operational track record. Our standard SLA specifies availability percentage, recovery time, and liability cap.

API and tech-asset IP belongs to ONDA, while the partner's sales · customer · operational data IP remains the partner's asset.

The standard contract includes a mutual NDA for 5 years, and on termination, a reasonable transition period is guaranteed for channel mapping and booking data export. No lock-in.

Yes, ONDA's booking engine and websites are designed to be LLM-friendly.

Applied Technologies: - Automatic Schema.org structured data - AI crawler access (GPTBot, Claude-Web, etc.) - llms.txt standard support

This ensures accurate property information appears in AI searches like ChatGPT, Claude, and Perplexity, allowing you to reach travelers who receive accommodation recommendations through AI.

Reservation and settlement data moves over encrypted connections (HTTPS) and is backed up on a regular schedule.

• Access to the partner dashboard and mobile app is separated by account-level permissions
• You can export reservations and settlement records to Excel at any time, so your data always stays in your hands
• How we handle personal data is documented in our privacy policy

If you need specifics — certification scope, data residency region — let us know and we'll come back to you with a straight answer.
