Core Modules

Guest Communication

The OneAvant in-room tablet, your guest’s portal to a superior stay. Branded and customized to your identity. The OneAvant guest experience app, a mobile version that lets your guests chat and order on the go. Guests can chat with the hotel, send voice messages, and enquire about your services, all in one place. Instant 

in-chat auto-translation that supports 100+ languages. Removing the language barrier completely. A new angle on the in-room phone, guests can call your staff or departments depending on availability, and even hop on a video call.

Guest Journey

Start your guest’s experience before they arrive, our welcome emails include enticing upsells directly from your catalogue. Customize your paperless pre-check-in form, which guests receive via email or WhatsApp to ensure a fast check-in experience. Or use the paperless check-in on-arrival for easy, eco-friendly information collection. Boost your revenue by giving guest multiple opportunities before they arrive, and during their stay to upgrade, get add-ons, or make special requests. Keep a record of your guest’s preferences, to make each stay at your hotel a personalized and unique one.

Ordering & Services

Guests can order food using our intuitive menus and dining feature, customizing each order, and even scheduling orders in advance. Upsell your guests on addons, upgrades, and services using our smart-upsell system, that lets you show the right upsell at the right time. Allow your guests to request room-cleaning, wake up calls, taxis and much more directly from the app.

Curated Content for Guests

Guests can find guidebooks to walk them through your amenities, local sights and much more, inserting relevant upsells at the right time. Or they can receive posts and announcements about upcoming events, activities, and limited availability services.

Managed by your team

With admin tools designed to be as easy as posting on social media, our system lets you add new dining and activities menus, post announcements, write guide books, and create upsells directly from the admin panel.

Each piece of content tracks how many views, and engagement it had, and can easily be disabled and enabled for your guests.

Your Software & Your Brand

All guest facing screens from the mobile app, to the pre-check-in, and in-room tablets all have your branding, logo, colors, and a theme to give your guests the exact experience you envision.

No Guest Experience is complete unless the guest experiences it your way.

Traceability & Administration

With a robust user management system, all your staff will have access to only what they need to have. Staff can engage with the guests from the admin panel, or from the Companion App, allowing them to have an intuitive, and easy way to keep up with what they need to do. Escalation and alerting means no guest request goes unnoticed, if something slips by staff, managers get prompted to look into it.

Smart Rooms

Transform the guest experience with OneAvant’s native smart solutions, offering one-touch control over lighting, climate, and locks. Designed for easy integration at any stage of your hotel's lifecycle, our open-hardware system guarantees wire-free installation in hours, proactive maintenance alerts, and seamless scalability without vendor lock-in.

Supporting
Hospitality Standards & Compliance Goals

Share insights automatically

Schedule PDF or live-link Databoard shares to email or Slack. Include AI-written executive summaries so leadership reads the story, not just the chart.

Bring chat, WhatsApp, voice and video calls, service requests, order updates, and AI translation into one staff view so teams can act quickly and guests never feel ignored.

OneAvant GMS Vs Duve

While Duve is a solid web app, OneAvant GMS is a complete all-in-one hospitality ecosystem that combines software (check-in, upsells, staff ops) with hardware (tablets, smart-room controls).

Why OneAvant stands out

Guest channels

In-room tablet, mobile guest experience app, web experience, WhatsApp, and staff companion/admin tools.

Primarily web-based guest app with multichannel messaging.

OneAvant gives hotels more controlled guest touchpoints, especially through the dedicated in-room tablet and branded app experience.

Smart room control

Native control for lighting, HVAC, curtains, DND, door locks, scenes, sensors, and room automations.

Available mainly through third-party integrations and providers.

OneAvant has a major advantage for hotels that want guest experience and IoT in one connected ecosystem rather than relying on external smart-room vendors.

In-room tablet
experience

Dedicated tablet app for guest communication, ordering, services, guidebooks, activities, and room controls.

No dedicated in-room tablet offering.

OneAvant canreplace or modernize the traditional room phone/directory with a premium in-room digital hub.

Guest communication

Unified inbox with native chat, WhatsApp, voice and video calling, service requests, order updates, activity enquiries, AI translation, and suggested responses.

Strong multi-channel messaging with AI capabilities.

OneAvant turns communication into an operational workflow, not just a messaging layer, by tying requests, orders, calls, and enquiries into the same staff view.

Ordering and room
service

Menu management, modifiers, scheduled orders, approval rejection flows, guest notifications, and staff order handling.

More limited; generally handled as upsells or guest app offers.

OneAvant is better suited for hotels with restaurants, bars, room service, spa services, or bookable experiences that need day-to-day operational handling.

Service requests

Room cleaning, wake-up calls, concierge, SOS, taxis, and other requests tracked through the app and chat.

Supported more indirectly through guest app flows and upsells.

OneAvant provides clearer accountability for staff and a simpler guest path for common hotel needs.

Pre-check-in and
upsells

Custom pre-check- in forms, document collection, preference capture, approval/rejection workflows, and contextual upsells before and during the stay.

Strong online check- in, document collection, preference gathering, and profile-based upsells.

Both platforms are competitive here, but OneAvant connects upsells into tablets, guidebooks, guest apps, emails, and operational workflows.

Branding and
customization

Property-level branding, themes, styling, dedicated branded mobile apps, and branded tablet experience.

Customizable branding for the guest app experience.

OneAvant offers deeper brand ownership, especially for hotels that want the guest journey to feel like their own digital product.

Multi-property setup

Each property can have its own PMS integration, branding, currency, location, rooms, guests, reservations, and operational setup.

Multi-property support available, typically with unified billing.

OneAvant is flexible for hotel groups that want central oversight while preserving each property’s identity and operational setup.

Analytics and BI

Guest/staff activity tracking, upsell performance metrics, and potential integration with OneAvant BI for richer reporting and dashboards.

OneAvant can extend beyond standard dashboards into broader business intelligence and operational insight across the OneAvant ecosystem.

Implementation and maintenance

Training, documentation, customer success support, smart-room maintenance guidance, and scalable smart-room upgrades without heavy rewiring.

Support available, but smart-room maintenance is more dependent on third-party providers.

OneAvant is more attractive for hotels that want one partner responsible for the guest experience layer and the smart-room layer.

Best fit

Hotels that want a premium, branded, operationally connected guest journey across pre-arrival, in-room, mobile, staff, and smart-room experiences.

Hotels that mainly need a strong web-based guest app, online check-in, upsells, and multi-channel communication.

OneAvant is the stronger choice when the hotel wants to go beyond guest messaging and build a fully connected smart hospitality experience.
