Capabilities
We partner with you to improve your operations and guest experience by building deep, real-time integrations with RMS Cloud
Eliminate front desk lines with contactless check-in that syncs with RMS Cloud.
We help you build contactless check-in flows that sync guest arrival status, trigger room assignments, and enable mobile key access.
Your guests thus get the immediate, reliable arrival experience they expect, and front desk staff are freed to focus on high-value interactions instead of manual key handovers.
Keep guests on your branded website from search to checkout, no third-party redirects.
We build a direct booking experience that sits on top of RMS Cloud, giving you full control over your brand identity and conversion flow.
You thus eliminate third-party redirects and see a 25% rise in direct revenue, keeping high-converting direct traffic on your branded site.
Turn your app into a revenue channel with pre-arrival offers.
We integrate real-time room availability and pricing from RMS Cloud to deliver personalized upgrade and package offers directly through your guest app.
Your business thus thrives by generating 15-25% incremental revenue from in-app upsells, all with zero staff effort.
Replace physical keys with Bluetooth-enabled apartment access synced to RMS Cloud.
We connect RMS Cloud check-in status with smart lock providers (OmniTec, Salto, etc.) so access is automatically granted when check-in is confirmed.
You thus eliminate operational headaches and achieve cost savings (reduced key replacement costs) and a 60% reduction in front desk coordination time.
Let guests request anything and route it directly into your operations system.
We route guest requests for housekeeping, maintenance, or late checkout directly into RMS Cloud task management.
Your staff respond faster: 40-60% reduction in request response time, with every task logged and tracked against the guest record.
Reward returning guests with points and perks synced to RMS Cloud profiles.
We track lifetime value and personalize offers based on stay history to incentivize repeat bookings.
You thus nurture deep customer relationships, typically seeing a 25-35% increase in repeat bookings within six months of launch.
Automatically update rates across all booking platforms.
We connect multi-property clients' RMS Cloud with their channel managers (like Guesty and Cloudbeds) and OTAs (like Booking.com and Airbnb) to instantly sync your rates and availability, guaranteeing accuracy.
You thus eliminate tedious manual updates and prevent costly overbookings, saving your team over 10 hours per week of manual work and freeing them up to focus on guests.
Pull booking data, occupancy rates, ADR (Average Daily Rate), and guest behavior metrics from RMS Cloud into custom dashboards that drive smarter decisions.
We build custom dashboards that consolidate data from multiple RMS Cloud instances, giving general managers instant visibility.
Your leadership team sees a live, consolidated view across all properties: occupancy, revenue, and guest metrics in one place without needing to log into each system separately.
Capture real-time guest feedback and automatically update guest profiles in RMS Cloud.
We integrate third-party review and survey platforms (like TrustYou or Revinate) directly with RMS Cloud, syncing ratings and comments to the corresponding guest profile.
You thus transform guest criticism into actionable operational improvements and gain a 360-degree view of every guest, improving personalized service and driving higher review scores.
How we work
Every project follows the same four phases. Scope is locked and price is fixed before development starts.
We map your current tech stack, integration points, and guest journey. You leave week 1 with a written scope document, a data-flow diagram, and a fixed-price quote. No development starts without your sign-off.
Wireframes and API architecture before a single line of production code. We test against the RMS Cloud sandbox environment before moving to build. Design decisions made here cost ten times less than the same decisions made in week 8.
Working software at a staging URL by the end of sprint one. Bi-weekly demos. QA runs in parallel with every sprint, not as a phase at the end. Integration is tested against live RMS Cloud data before go-live.
Production deployment with monitoring activated on launch day. 8 weeks of post-launch support included in every project. Ongoing retainer options available for feature roadmap and maintenance.
Why us
The engineers who assess your integration also build it. No bait-and-switch, no offshore handoff after the contract is signed. We have direct access to RMS Cloud's engineering team and have shipped live PMS integrations for properties in Ireland, the US, and the Middle East.
We scope the work, calculate the cost, and lock it in writing before any development starts. A scope change is a change request: priced, agreed, or dropped. It never absorbs into the project and appears on the final invoice.
Clients include Vodafone, T-Mobile, Aldi, Nike, Cisco, and Lockheed Martin. Track record spans AI, SaaS, mobile, and enterprise platforms across healthcare, fintech, logistics, and hospitality.
GDPR, PCI-DSS — compliance requirements are scoped in week 1, not retrofitted before launch. We have shipped GDPR-compliant products for European markets and PCI-DSS-compliant payment handling for hospitality clients.
Partner with an RMS Cloud certified developer who specializes in building hospitality apps that actually drive revenue.
Process
Building a PMS-integrated app is about creating guest experiences that work in real-time, not just connecting APIs. Our RMS Cloud certified development services follow a proven process that combines hospitality expertise, technical integration, and user-centered design to deliver results that support your revenue goals.

We begin by thoroughly understanding your current technology stack and the complete guest journey before any coding starts. This phase involves mapping all existing systems (like RMS Cloud, channel managers, and payment gateways), identifying critical integration points, and defining your target guest experience goals and business KPIs.
Deliverables:
System Mapping & Data Flow Document
Defined Guest Experience Goals & KPIs
Technical Roadmap & Integration Architecture
Documented API Specifications
Next, we design and develop your high-performing, guest-facing application. This includes creating intuitive mobile/web interfaces, building secure, real-time API connections to RMS Cloud, and adding custom features like mobile check-in. All development is rigorously tested in the RMS Cloud sandbox environment.
Deliverables:
High-Fidelity UI/UX Designs
Functional Mobile/Web Application Codebase
Secure RMS Cloud API Integration
Completed Sandbox Integration Testing
We ensure a smooth launch across all guest touchpoints. This involves deploying the application, connecting to the live RMS Cloud environment, and integrating with your existing tools (CRM, payment processors). We train your team, ensure data security compliance, and establish continuous performance monitoring.
Deliverables:
Production Deployment & Live System Integration
Admin Workflow Guide
GDPR/Privacy Policy Integration Review
Technical Handover Documentation
The final phase applies real guest data to continuously improve engagement and drive incremental revenue. We track adoption and booking behavior to inform A/B testing and feature additions based on feedback. We also scale infrastructure as booking volume grows, providing ongoing technical support and critical updates.
Deliverables:
Performance & Adoption Metric Reports
A/B Test Results & Optimization Recommendations
Feature Roadmap based on Feedback
Ongoing Technical Support & Maintenance Plan
Why us
We are RMS Cloud certified experts. That means we have deep operational knowledge of their API, understand their data model, and have direct support access for complex integrations.
We offer transparent pricing, allowing you to choose between fixed-price projects or monthly retainers. There are no surprise invoices, so you know exactly what you're paying for upfront.
We've built PMS integrations for serviced apartments. We understand RevPAR, ADR, booking windows, and the unique workflows of hospitality operations.
For one of Ireland’s premier providers of short- and medium-term furnished rentals, City Break Apartments (150 serviced apartments, Dublin), we achieved a 25% direct revenue increase and saw 70+ weekly self check-ins.
We prioritize clear communication. We are always available on Slack, ensuring no ghosting or excuses, just fast and honest updates throughout your project.
We also assign dedicated project managers to oversee the process and ensure we follow the Agile methodology. Additionally, we use Asana for task updates and conduct regular sprint meetings to make sure we are always on the same page.

01 / 07
Connect one tool (channel manager, payment gateway, CRM) to RMS Cloud with API sync.
Build a mobile app (iOS + Android) or web app with core guest features and RMS Cloud integration.
Complete custom solution with multiple integrations, advanced features, and ongoing support.
Process
You want your app to talk to RMS Cloud without breaking your existing systems. We handle the technical heavy lifting so you don't have to. Below are the most common integrations we build and how we execute them.
We connect your app to RMS Cloud's reservation, guest profile, and room inventory APIs. This powers real-time booking sync, mobile check-in, and upsell features.
We connect guest data from RMS Cloud to your CRM, so your marketing team can segment, personalize, and automate email campaigns based on stay history.
We sync RMS Cloud with your channel manager so rate and availability updates push to all OTAs (Booking.com, Expedia, Airbnb) automatically.
We integrate secure payment processing so guests can pay for upgrades, add-ons, or deposits directly through your app, with transactions logged in RMS Cloud.
We build loyalty programs that sync with RMS Cloud guest profiles, tracking points, tier status, and redemptions across all bookings.
We integrate digital key systems so guests can access their rooms via your app, with check-in status synced to RMS Cloud in real-time.
Features
Guests hate outdated information. We sync booking status, room assignments, and guest preferences in real-time with RMS Cloud, so your app always shows accurate data.
Whether a guest books through your website, an OTA, or directly with the front desk, your app reflects their reservation instantly. No more "We don't see your booking" awkward moments at check-in.
Wi-Fi goes down. Connectivity fails. We build apps that cache critical data locally, so guests can check in, view their reservation, and access their digital key even when the internet is spotty.
Perfect for remote resorts, RV parks, or campgrounds where cellular coverage isn't guaranteed.
Hospitality data is sensitive. We build PCI-DSS-compliant payment handling and GDPR-compliant guest data management.
Your guests' credit card info, passport details, and booking history are encrypted end-to-end. You get peace of mind knowing you're audit-ready.
International guests expect localized experiences. We integrate RMS Cloud's guest profile data (language preference, nationality) to auto-switch your app's language and display pricing in their home currency.
If you operate in tourist destinations like Dubai, Paris, or Miami, this feature alone boosts conversion on upsells and direct bookings.
Your app triggers timely, contextual messages based on RMS Cloud booking status, such as pre-arrival welcome, check-in reminders, upsell offers, and post-stay review requests.
These automated pre-arrival upsells can generate $15K–$25K additional revenue per quarter for 150-200 room properties with zero manual effort.
Your hotel booking app should look like your brand, not a generic hotel app. We design custom UI/UX that matches your property's aesthetic, from boutique minimalism to luxury resort vibes.
If you manage multiple properties, we can build a white-label platform where each property gets its own branded app while sharing the same RMS Cloud backend.
Use cases
Drive more bookings through your own channels, not OTAs. We build custom booking engines and guest apps that integrate with RMS Cloud, reducing OTA commissions and increasing direct revenue.
Stop wasting time on manual tasks. Automate data entry, guest check-ins, and service requests by connecting RMS Cloud with your front desk tools and guest-facing apps.
Add new revenue streams. Integrate upsell features (room upgrades, spa, F&B) directly into your guest app, powered by real-time RMS Cloud inventory and pricing data.
Happy guests leave better reviews and book again. We build frictionless experiences (mobile check-in, service requests, upsells) that sync with RMS Cloud to delight guests at every touchpoint.
If you manage multiple properties (hotel chain, RV park network), we build centralized dashboards that pull data from multiple RMS Cloud instances into one unified view.
Turn data into actionable intelligence. We build custom analytics dashboards that pull RevPAR, ADR, and occupancy metrics from RMS Cloud, providing GMs and executives with a unified, accurate view necessary for smarter forecasting and strategic decision-making.
