Who We Work With

Who We Build Travel Software For

From an OTA startup aggregating inventory to a boutique tour operator digitising custom package quotes, we build travel software tailored to your specific booking economics and distribution model.

Online Travel Agencies (OTAs) & Aggregators

Multi-vendor booking platforms connecting travelers with flights, hotels, tours, and activities under one brand.

Tour Operators & Destination Management (DMCs)

Custom package builders, inventory management, fixed-departure booking engines, and supplier voucher generation.

Travel Startups & Niche Mobility Platforms

Curated travel experiences, group trip planners, adventure booking, and social travel apps designed for high engagement.

Corporate Travel & Event Specialists

Business travel booking portals with policy compliance, approval workflows, expense tracking, and group itinerary management.

Trust
Booking Logic & Traveler Trust

The Booking & Inventory Engine Is The Product

Travel software fails on stale inventory, failed payment handoffs, and broken vouchers, not on hero images. Here is how we build reliability into the core.

Real-Time Inventory Synchronization

Prevent overbooking with live API sync across GDS, hotel channel managers, and local supplier inventories.

Multi-Currency & Multi-Language Checkout

Localised booking flows with dynamic currency conversion, regional payment gateways, and tax calculation.

Interactive & Offline Itinerary Access

Day-by-day itinerary view that works offline during travel, complete with vouchers, maps, and flight alerts.

Automated Voucher & Invoice Generation

Instant generation of branded PDF vouchers, supplier booking confirmations, and tax-compliant customer invoices.

Dynamic Package & Pricing Engine

Combine flights, hotels, transfers, and activities into custom packages with automated markup and discount rules.

Full Code, Data & Supplier Ownership

You own 100% of the source code, customer database, and direct supplier contracts with zero per-booking commission to us.

High-Concurrency Peak Search Architecture

Engineered to handle search spikes during holiday sale periods without inventory API timeouts or page crashes.

Cancellation & Partial Refund Workflows

Automated refund calculations based on supplier policy tiers, credit note generation, and wallet balances.

Supplier & Sub-Agent B2B Portals

Dedicated login portals for suppliers to manage allotments and sub-agents to book with custom commission tiers.

Flight & Transport API Integration

Direct integration with Amadeus, Sabre, Skyscanner, or local transport APIs for live seat maps and fare rules.

Review, Rating & Verified User UGC

Post-trip review triggers, verified traveler badges, photo uploads, and moderation controls in your admin panel.

Corporate Policy & Approval Engine

Set spending limits, advance booking rules, and manager approval chains for corporate travel booking.

See all 12 platform practices

We build the technology. We do not provide supplier inventory, GDS credentials, travel licensing, or customer traffic. A travel platform's success depends on your supplier relationships, API agreements, marketing budget, and customer service operations. Travel licensing (IATA, local tourism registration), payment gateway merchant category approvals, and supplier API access are your responsibility to secure. If your stage calls for a simple WordPress booking plugin rather than a custom app, we will advise you honestly.

Challenges
The Problem

What Breaks in Travel Software

We have built enough travel platforms to know where booking systems break under real-world conditions.

The Problem

Stale inventory leads to double bookings

Slow API sync between channel managers and your booking frontend causes double bookings and angry customers.

Complex multi-currency checkout fails

Travelers abandon carts when currencies flip unexpectedly or regional payment methods fail at final step.

Offline travelers lose access to itineraries

When network drops abroad, web-based itineraries become inaccessible, leaving travelers without voucher details.

Manual package quoting slows down sales

Boutique operators take 24-48 hours to assemble custom package quotes on spreadsheets, losing leads to faster competitors.

Our Approach

Real-time WebSocket & webhook sync

High-frequency caching with instant webhook invalidation so pricing and availability reflect live supplier status.

Native multi-currency payment routing

Upfront currency locking with localized payment gateways, clear fee breakdowns, and auto-conversion fallback.

Offline-first itinerary caching

Local device caching of all tickets, vouchers, maps, and day plans so travelers can access them anytime without data.

Automated dynamic package builder

Drag-and-drop itinerary builder with live supplier pricing that generates customer-ready proposals in 5 minutes.

“Ziyad and the entire Codex Lancers team have been simply amazing to work with while creating our 11:11 The Divine Mindset mobile app. Communication was outstanding throughout the entire project. They kept us fully informed at every stage, responded quickly, and were always patient, professional and genuinely committed to achieving the best possible result. Their feedback, ideas and suggestions were enormously helpful and significantly improved the finished app. The app they have created is stunningly beautiful in every way, with an elegant, polished design and flawless functionality. They understood our vision perfectly and brought it to life even better than we had imagined. I cannot recommend Ziyad and his team highly enough. Their technical expertise, creativity, attention to detail and dedication are exceptional. We will be using them for all our future app projects and look forward to working with them for many years to come.”

“I’ve been building with Codelancer (Ziyad and the team) for the past plus two years, and I highly recommend them to anyone in need of a reliable development team. They are deeply committed to their clients’ vision, communicate clearly, are impressively responsive, and have consistently turned complex ideas into fully functional products. Codelancer genuinely prioritizes client success. They don’t just write code -they share valuable insights, make thoughtful suggestions, and support you at every stage of the journey. Over time, they’ve become an integral part of our team, and it’s a real pleasure to work with them and have them by our side. I am very grateful to work with them and highly recommend them to all”

“Partnering with CodeX Lancers has been one of the best decisions for our project. From the initial UI/UX flow design to API implementation and complete end-to-end product guidance, their team consistently demonstrated strong product thinking. They don’t just execute tasks they ask the right questions, provide thoughtful suggestions, and help refine the overall direction of the product. Their involvement went far beyond development. They contributed strategic insights, improved workflows, and ensured that both the user experience and backend integrations were properly aligned. That level of ownership truly makes a difference. Timelines were respected, communication was clear and consistent, and every discussion felt productive and solution-focused. Instead of working with an external agency, it genuinely felt like we had added a committed product team to our side. Their attention to detail, UI clarity, structured approach, and proactive mindset gave us confidence throughout the entire journey. Highly recommended for anyone looking for a dependable team that genuinely cares about both execution and long-term product success.”

His Flutter/Dart expertise is solid, and he proactively solved complex challenges including offline sync and GPS tracking without being asked. What impressed me most: clear daily communication, clean code that's easy to maintain, and thoughtful suggestions that improved our original design. When integration issues arose, he fixed them independently rather than just reporting problems. Would definitely hire again and recommend to others needing reliable Flutter development.”

Book a free call

Can you integrate third-party travel APIs like Amadeus, Sabre, or Hotelbeds?

Yes. We have extensive experience integrating GDS platforms (Amadeus, Sabre), hotel channel managers (Hotelbeds, RateGain), flight aggregators, and activity suppliers via REST and SOAP APIs.

How does the offline itinerary feature work for travelers?

When a booking is confirmed, the mobile app downloads and locally stores all itinerary details, hotel vouchers, PDF tickets, offline vector maps, and contact information. Travelers can access everything abroad without requiring data or Wi-Fi.

Can you build a dynamic tour packaging engine?

Yes. We build dynamic packaging engines that allow travelers or travel agents to combine flights, hotels, transfers, and activities into a single customized itinerary with live price calculations and automated markup rules.

How do you handle multi-currency payments and pricing?

We integrate multi-currency payment gateways (Stripe, Razorpay International) with live exchange rate API feeds, allowing users to browse and pay in their local currency while settling to your account in your preferred base currency.

Can you build a B2B travel portal for sub-agents and wholesale bookings?

Yes. We build dedicated B2B portals where sub-agents or corporate bookers can search inventory, book trips using credit limits or deposit wallets, and access custom tier-based commission rates.
