Custom Serviced Apartment Software Development Services
Serviced apartment software development services
Serviced apartments run on different rules than hotels: flexible stay lengths, corporate billing, utility metering, multi-property rate management. Most PMS software isn't built for that. RaftLabs is an AI-first tech studio that builds web and mobile platforms around how serviced apartment operations actually work. RMS Cloud integrated. City Break Apartments (Dublin) is a live serviced-apartment build.

The brief
Start with what is not working.
Good software decisions begin with the constraint, not a list of features or a preferred technology.
01
Losing revenue because your PMS can't handle flexible billing for weekly and monthly stays?
02
Wasting hours daily on manual workarounds because your software wasn't built for serviced apartments?
Plain answer
RaftLabs builds custom serviced apartment software for operators across the US, UK, and Ireland. Platforms handle flexible stays, multi-property billing, keyless entry, and OTA sync. Shipping production software since 2015.
What to remember
- RaftLabs ships a validated first module and grows it into the full serviced apartment platform.
- Platforms handle flexible stay billing, multi-property rate management, and OTA integrations out of the box.
- A custom booking platform built for City Break Apartments (Dublin) grew self check-ins 7x and lifted direct revenue 25%.
- RaftLabs integrates with RMS Cloud, connecting the platform to the existing PMS.
- Platforms are built with enterprise-grade security controls: encryption, role-based access, and regular audits.
- Shipping production hospitality and property software since 2015.
Why serviced apartment businesses need custom software?
Serviced apartments sit between a hotel and a rental. Guests book for a night, a week, or six months, and the billing changes with every one. Most PMS tools were built for nightly hotel stays, so they buckle on corporate contracts, multi-property inventory, and anything that runs past a month.
Teams end up wasting hours every day on manual workarounds. Billing errors frustrate corporate clients. Double bookings damage your reputation. Guest communication falls through the cracks. And you're still paying monthly fees for software that creates more problems than it solves.
Custom software fixes that. The platform works the way your operation already runs. Billing for long stays runs itself. Your OTAs, payment gateways, and door locks talk to one system instead of five. Staff spend their time on guests, not on fighting the tools.
According to Emergen Research, the global hospitality property management software market was worth $4.8 billion in 2024 and is projected to reach $12.3 billion by 2034, driven by operators replacing generic tools with purpose-built platforms. For serviced apartment operators, that shift is not optional. It is how you protect margin as you add properties.
Most importantly, you own your technology. No vendor lock-in, no surprise fee increases, and no feature requests that sit in a queue forever. You get a platform that grows with your portfolio and an edge that stays under your control.

Where serviced apartment software is heading
Three shifts are changing how operators buy software, and each one favours a platform you own.
Guests now expect to arrive at 1am and let themselves in. Keyless entry and mobile self check-in have moved from perk to baseline, which is why the City Break build put 250 smart locks and a guest app at the centre, not on the roadmap for later.
Corporate and relocation demand keeps pushing stays past thirty days. That single fact breaks nightly-rate PMS tools built for hotels: prorated billing, utility metering, and monthly invoices are edge cases for them and the whole business for you.
And OTA commission keeps climbing. Operators are investing in direct-booking engines and length-of-stay pricing to hold margin, the same move that lifted City Break's direct revenue by a quarter. A platform you own lets you answer each shift on your own timeline, instead of waiting for a vendor's release notes.
Services
What we build
Property and unit management software development
Manage your entire portfolio from a single platform, with multiple properties, diverse unit types, real-time availability, and property-specific booking rules. Track assets, schedule maintenance, and configure pricing across locations, whether you manage 10 units or 1,000.
Booking and reservation software development
Booking engines built for extended stays, corporate accounts, and flexible check-ins, supporting direct website reservations, OTA channel integration, and duration-based pricing. Real-time calendar synchronization eliminates double bookings across all channels.
Guest experience and communication software development
Automate guest communication across the whole journey. We build guest experience applications and multi-channel platforms that personalize messages by stay length and guest type, with dedicated portals for extended-stay residents to manage bookings, request services, and view payment history. Where a guest shows up in several systems, the PMS, a channel booking, an email tool, a corporate-account spreadsheet, we resolve identity first: deduplication on email, phone, name, and card token merges those records into one profile before any dashboard or segment is built on top of it. Every guest task stays bounded by what the PMS can confirm: invitation and identity, arrival and access, payments and notifications, and a staff exception queue when something fails.
Housekeeping and operations automation development
Optimize staff efficiency with automated task management using hotel management software built for lean teams. Dynamic cleaning schedules, mobile work assignment, photo-verified completion, and preventive maintenance scheduling handle different service levels across short and extended stays.
Reporting, analytics and revenue intelligence dashboards
Dashboards that turn operational data into occupancy forecasting, revenue analysis by unit type and channel, and length-of-stay patterns. Dynamic pricing recommendations and role-based access let each team drill from portfolio to unit-level performance.
Billing, payments and invoicing systems
Handle complex billing: split payments, recurring invoicing for long stays, security deposits, and multi-currency transactions. Corporate invoice generation with PO tracking and consolidated billing across properties, integrated with payment gateways with PCI DSS controls on payment flows.
The first decision is not what to build.
It is whether software is the right answer at all. We use four possible recommendations before discussing a development scope.
- 01
Buy
Choose a maintained product when it handles the core property operations workflow and the remaining gaps can be solved with configuration, a connector, or a small process change. Paying for software you do not have to maintain is often the better trade.
- 02
Repair
Keep the existing product when users still get value from it and the code can be understood safely. Start with evidence: where the code lives, how the data is organized, what is tested, which outside services it depends on, who can access what, and how updates go live.
- 03
Build
Own the system when property operations shape margin, customer experience, speed, or a product customers pay for. Start with one complete path and the system connections that path cannot work without.
- 04
Wait
Do not turn a changing policy into permanent software. Stabilise the rules, name the workflow owner, and measure the cost of the current process before paying for a product.
Not sure which path is yours? Bring it to a 30-minute call. Leave with the answer in writing.
How we work
From scope to live serviced apartment platform
Every project follows the same four phases. PMS integration and payment compliance are designed in from the start.
- Step 0101
Property operations audit and scope
We map your booking sources, PMS connections, guest communication flows, and access control requirements. We identify what needs to be built custom versus what can be integrated from existing systems. You leave the audit with a written scope and a fixed price, locked before development begins.
- Step 0202
Guest journey design
UX design for the full guest journey: booking, pre-arrival communication, keyless check-in, in-stay service requests, and post-stay review. Technical architecture for real-time availability, channel sync, and payment processing.
- Step 0303
Development and integration
Development in iterative steps. Booking engine, guest app, PMS integration, and keyless access system built against the spec. Working software in a staging environment you can click through early in the build.
- Step 0404
Launch and support
Production deployment, staff training, and documentation, with monitoring switched on from day one. Post-launch support included: integration edge cases, booking flow issues, and performance tuning.
Why us
Why teams choose RaftLabs
- 01
Senior engineers build what they scope
The engineers who assess your problem also build the solution. No bait-and-switch after the contract is signed. The team you meet at scoping ships the build.
- 02
Fixed price before development starts
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 does not absorb into the project and appear on the final invoice.
- 03
A decade of shipped products
Real engagements across SaaS, fintech, healthcare, and logistics, not every one published as a named case study. We have shipped AI, SaaS, mobile, and enterprise platforms across healthcare, fintech, logistics, and hospitality since 2015.
- 04
Compliance built in from the start
GDPR, PCI DSS and other compliance requirements are scoped before development, not retrofitted before launch. Platforms ship with encryption, role-based access, consent handling, audit trails, and payment flows built on PCI DSS controls.

Custom software vs off-the-shelf PMS for serviced apartments
Services
What we build
Direct reservations
Capture more bookings and eliminate commission fees with a custom booking engine integrated into your website. Conversion-optimized reservations handle nightly to monthly stays, show real-time availability across the portfolio, and calculate dynamic pricing by length of stay. Use OTAs to acquire guests and your own guest experience to retain them: app-only perks and best-rate guarantees pull repeat bookings off the commission channels.
Revenue management
Maximize income with intelligent pricing built for serviced apartments. Revenue management features include dynamic pricing that adjusts by demand, occupancy forecasts, and seasonal patterns, with performance tracked by channel, property, and guest segment.
Automation tools
Reduce manual work with workflow automation across operations. Automate guest communications, trigger housekeeping from check-ins and checkouts, schedule recurring billing for extended stays, and send maintenance alerts, with rule-based triggers for any operational workflow.
Multi-unit management
Manage your entire portfolio from one centralized platform, whether 20 units in one building or 500 across cities. Unified control with property-specific pricing and policies, staff permissions by location, and asset tracking at both portfolio and property levels.
Channel manager integration
Distribute inventory across major OTAs while maintaining rate parity and avoiding double bookings. Update pricing once and push it across every channel in real time, with all bookings flowing into your central system and channel performance tracked to optimize commission costs.
Access and identity verification
Enable contactless check-in with smart access control. Unique access codes generate and deliver automatically on booking confirmation, guests complete identity verification through your app or web portal, and all entry activity is logged, ideal for late arrivals, extended stays, and unstaffed properties. A safe arrival loop covers invitation and arrival readiness, identity and payment checks, credential issue and lifecycle, and staff exceptions when something fails.

Common questions
A first module (booking engine or property management) launches so you can start taking direct bookings early. A full-featured platform across web and mobile follows. We give you a fixed scope and timeline after discovery, then expand from the validated v1.
Yes, we specialize in smooth integrations with existing systems. We will help you integrate your platform with PMS platforms (RMS Cloud, Opera, Mews, Cloudbeds, etc.) and all major OTAs (Booking.com, Airbnb, Expedia). Your data and workflows remain intact.
Custom software gives flexibility, scalability, and control tailored specifically to your operations. Off-the-shelf solutions work for generic use cases, but serviced apartments have unique needs (flexible stays, complex billing, multi-property) that generic PMS often can't handle effectively.
Yes, we provide post-launch support, and we also offer ongoing maintenance packages that include technical support, security updates, performance monitoring, and new feature development.
Yes, we handle complete data migration from your existing PMS or spreadsheets. We protect data integrity, map fields accurately, and test thoroughly before going live. Your historical data remains accessible.
Most changes can be implemented easily since we have deep knowledge of the product we developed for you. For significant new features, we provide transparent quotes and timelines. Many clients retain us for ongoing development.
Yes. We recommend a phased approach for all of our clients. Start with core features (booking, property management, guest portal) and add advanced features (channel manager, revenue management, owner portal) as you grow.
We implement enterprise-grade security including SSL/TLS encryption, secure data storage, role-based access controls, and regular security audits.
Length of stay and staffing. Hotel software assumes nightly rates plus a staffed front desk; serviced apartments run weekly and monthly rates, corporate billing, mid-stay cleans, usually no desk. A hotel PMS can be forced to work, but the rate model and the guest-contact profile both fight you. The two classic mistakes: buying a hotel PMS and bolting on short-term-rental distribution, or buying a rental stack and hoping corporate clients tolerate it. They will demand consolidated invoicing in month one.
Mews is the flexible cloud PMS with a broad marketplace, suited to small-to-mid and boutique operations. RMS Cloud is the feature-heavy platform for larger operations with complex revenue and financial needs, including trust accounting. The fit axis is operational complexity, not brand. Shortlist on three things: weekly and monthly rate plans, extension handling that does not require a rebooking, and corporate invoicing. Verify each against your own booking patterns.
Ask: what happens on day 12? Most demos show arrival and departure, but the real volume is mid-stay. Run the five tests: an end-to-end stay extension (guest asks, system checks availability, reprices at the weekly rate, updates the PMS, confirms); does the PMS integration write or only read; does voice share a history with messaging; can it handle corporate billing questions; and what breaks mid-stay? If a human must touch the PMS during the extension, it is a nicer inbox, not an integration.
Start with the operational pain: mid-stay cleaning is the single most common source of scheduling conflict and guest complaint in this segment. Does the system handle it: standardized turnover checklists, channel-manager plus housekeeping sync? Check the rate story: can it do weekly and monthly plans natively, or does it fake them? Confirm the channel story: OTA plus corporate and relocation channels, with rates, availability, and booking details synced to prevent double bookings. And ask the write question: integrates with Mews usually means read-only, so demand write access explicitly.
Yes, we build multi-property, multi-currency, and multi-language platforms. Our systems handle different tax rules, currencies, and languages reliably across your entire portfolio.
Use responsive web when camera, payments, and standard browser features cover the task; it reaches every guest without an install. Go native only when Bluetooth keys, reliable push, offline credentials, or repeat loyalty use justify install friction and app-store operations. Many properties start with mobile web and go native once the guest base and loyalty program earn the download.
OTAs are good at acquiring guests and bad at keeping them: every booking costs commission and hands the guest relationship to the OTA. Your own guest experience earns direct bookings, pre-arrival personalization, and in-stay upsells without manual work. Use OTAs to acquire and your own app to retain.
Ask how they will integrate with your PMS and channel manager. A confident, specific answer is a good sign; a vague one is a warning. Demand documented, versioned APIs, two-way sync for availability, rates, inventory, reservations, and cancellations, webhook support, payment tokenization, failure handling, and monitoring. Ask how long each integration takes and who owns it when the PMS changes its API.
It depends on the product, edition, region, partner access, API coverage, webhooks, sandbox, certification, rate limits, and commercial agreement. We have delivered an RMS Cloud integration for City Break Apartments; other providers must be qualified before scope. A vendor name alone does not prove the required reservation, folio, or room data is available.
Usually the PMS stays authoritative for property, inventory, reservation, room assignment, stay status, and folio state. The guest experience owns presentation, task status, and device behavior; access, payments, identity, loyalty, and messaging may each have their own system of record. Document each field and event rather than relying on a broad ownership statement.
Use stable provider and internal identifiers, idempotency keys, event versions, ordering rules, retries with limits, dead-letter queues, reconciliation jobs, and visible operator exceptions. Treat webhooks as notifications, not unquestioned truth: fetch current state before irreversible guest or financial consequences.
Drive adoption with best-rate guarantees for app bookings, app-only perks like WiFi upgrades and late checkout, QR codes at the front desk and in rooms, and staff mentions at check-in. Measure app opens and in-app actions, staff hours saved, ancillary revenue, and printing savings, not vanity downloads.
You should. Export reservations, guest profiles, agent records, and historical transactions before signing. Ask the exit story first: what leaves with you, in what format, and what does leaving cost? A vendor who cannot answer the exit question is telling you something. Demand one deduplicated guest profile, not scattered records.
Mobile check-in uses the guest's own phone with no hardware to maintain; it suits independents, boutiques, and unstaffed properties. Kiosks are lobby terminals that print key cards, with hardware maintenance and high upfront cost; they suit high-volume walk-in properties. Confirm smart-lock compatibility first: it is the gate for mobile key.
Use only the checks your approved policy requires. Explain the purpose, collect the minimum data, limit access, set retention, and route mismatches to trained staff. We build the workflow; your legal and operating policy determines the identity, registration, and privacy requirements.
Yes, guests can receive a digital room key on their phone when the lock hardware, phone, property network, and approved security model support it. Issue the credential for the approved room and time, activate and refresh it safely, and revoke or expire it after room moves, extensions, or checkout. The classic failure is check-in succeeding while the key still points at the old room, so room-ready state, lock activation, and credential issue must reconcile. Keep a staffed physical or coded fallback.
Ask the vendor directly: do automated identity checks replace manual passport copying, is the registration card e-signed, are deposits and payments collected with PCI controls, and can they show input sanitation and access-code handling? If they cannot, that is your answer.
