Travel booking software development

Contact us

Automate, optimize, and grow your travel bookings. With the right custom booking software, you can get a competitive edge by making your travel experiences the best they can be. At COAX, we revolutionize booking software for travel companies by using cutting-edge tools that enable your business to stay ahead of the curve.

One partner for each hotel software development service and solution

Travel portal development

Your online travel business needs efficient and robust travel portal software that makes it easy to find and book hotels, transfers, tours, and vehicle rentals. We develop unique solutions that fit your travel agency and customer needs, with portals that consolidate all data touchpoints in one place, allowing this holistic approach to boost your loyalty and revenue.

Booking engines

Make it simple to connect with thousands of online travel packages, agents, and services with travel booking engine software. With travel booking engine software development, you connect to thousands of packages, agents, and services with clear search flows, smart filters, and payment gateways. Our GrandBus ticketing platform runs this kind of engine at scale.

Online travel agency software (OTA)  

Full-cycle OTA development improves your marketing, sales, finance, and reporting. We build hotel booking software solutions that centralize operations across your agency, making it easier to manage suppliers, track commissions, and serve customers. Our MICRM tour platform is a direct example, where this approach drove a 40% profit increase.

GDS Integration

We wire your platform into leading Global Distribution Systems so inventory, pricing, and availability stay live across every channel. Whether you need a B2B travel booking tool or a consumer-facing portal, one integration gives you real-time access to global travel products, just as we proved while building Re:Plan's marketplace infrastructure.

Travel API integration

Nowadays, online travel booking software development demands the best-in-market features and providers, and we ensure it with skilled third-party API integration. COAX experts maximize platform potential with minimal friction. For instance, for scalable minibus ride booking software development, we integrate varied payment methods and online maps for navigation.

Price comparison engines

We condense large inventory databases into clean, filterable listings with side-by-side comparisons for hotels, packages, or routes, which is a core feature in any solid travel portal. Our Stayaltered property search uses this logic to help guests quickly match stays to their values and budgets.

Visual calendars

Two-way synced calendars let customers check availability at a glance, removing the need for agents to verify each booking individually. We embed these during custom booking software development to give your team a real-time, all-around perspective, which is the same approach behind our trip scheduling tools.

Sustainability calculators

Eco-aware travelers expect to see their footprint before they book. We build emissions and sustainability calculators directly into booking flows, letting users compare options by carbon impact and offset costs. Our custom-developed emissions modules handle exactly this, including automated carbon tax payments.

Fee management

A unified fee management layer automates invoice generation, commission splits, and accounting sync across your platform. Agents stop chasing paperwork, and finance gets clean data automatically. For instance, we connected this kind of system to supplier networks in our tailored CRM for travel operations.

Provider and driver apps

Your operators, guides, and drivers need dedicated mobile tools that connect to the main platform in real time. We build online travel booking software development solutions that include provider-facing apps for schedule access, check-ins, and on-the-go ticket sales, just as we delivered for GrandBus driver operations.

Our development process

We dive into your booking flow from end to end and find where reservations fall off, staff fills gaps manually, and third-party tools that create friction. Your sales channels, supplier contracts, and customer paths all come under review. Every requirement for every role gets listed.

As your booking software development company, we choose the stack, define integrations, and rank features by business impact. Together, we decide what gets built first - payment processing, inventory sync, or channel connections. Deadlines and phases are locked in here.

We create designs around real usage patterns: agents pulling itineraries, travelers filtering and confirming in a few steps. Each role gets a dashboard built around what they need to see. You review every screen and call out changes before we get to the next step.

We build in cycles, releasing working modules for your sign-off each week. For travel booking engine software development, that means live availability feeds, multi-method payment flows, and supplier connections built and verified in iterative stages.

Every flow gets pushed hard. We check simultaneous bookings, mid-session rate changes, payment failures, and peak load spikes. Each integration is checked on its own and end-to-end. Issues get resolved before release and are thoroughly documented.

We stay with you way after launch if you need us to. We keep tracking performance, patching during quiet hours, and scaling capacity as demand grows. New routes, suppliers, or booking types get added without touching what already runs clean.

Client feedback


I was most impressed by the quality of the end product.

While my ideas formed the basis for the work, they delivered a far more superior product than I imagined with greater flexibility and viability of features. They exceeded expectations so many times it got to the point I couldn't wait to see what they came up with next.

Dan Brooks

President, Krytter

I implicitly trust the whole COAX team to do the right thing by location:live, and to have blunt and honest conversations with me when we are in the thick of delivery. COAX are the engine room and compass behind our market-leading tech.

Frequently asked questions and answers

Yes! Third-party APIs are the most crucial factor in travel apps. Our travel booking software developers can select the best travel and booking APIs, integrate any travel-related API of your choice into an existing website/mobile application, or help you determine which APIs your booking engine needs to make it better than the competition and support more advanced functions.

We know how to turn your ideas into fully-fledged software! At COAX, we recommend conducting a discovery phase at the beginning of every project to understand your ideas, analyze user demands, and pick the necessary features that can make the perfect software for all. When you're set to develop software from scratch with only an idea, we can help you define what it should and will look like after considering everything.

Definitely! Our custom-made software is always designed and developed with scalability in mind. If you let us in about how you would like to approach scaling at the beginning of the project, it will simplify the work for the future because we will be able to think more effectively about the project architecture to accommodate features with growth in mind. Our team can also assist you in scaling an already existing software to meet your present criteria and equip your platform with the latest advanced tools. With a modular approach, we can always add more features or whole systems to your infrastructure, like a travel hotel booking platform to your existing flight booking system, ensuring seamless integration without disrupting current operations.

We provide on-demand support for products we have developed or updated. As part of the support, our QA experts can test the products in the agreed period and ensure that the software works as required. Also, we can constantly collect feedback from users, discuss it with the client and jointly come to decisions for improvement, and implement changes that were agreed to improve the software. In addition, if you come up with new ideas after the main development phase is completed, we always have your back to bring them to life!

Our travel booking app development services help you adjust to any requirements and user needs, and sure, mobile-friendliness and accessibility are a must in software development. Our vetted experts know it. Users today prefer platforms that run on all devices, which is why we ensure that our software is supported on all platforms, devices, and browsers as long as you wish for the same. We can design your travel portal to work on any Android or iOS device and beyond!

At COAX, we conduct separate UX audits for existing software in the beginning to ensure that every feature and aspect of your travel software can be updated and tailored to match user needs. When developing custom software from scratch, our experts add everything to make the user journey simple and satisfying for your team, customers, and everyone else onboard. It's part of the process for us to create a user-friendly and appealing interface as the foundation of your travel booking system.
