Travel & Hospitality · Corporate Travel Booking Engine
Tripare
B2B SaaS — Corporate Travel Management Platform with multi-supplier booking engine, policy enforcement, multi-level.
The brief
Build and deliver a production-grade corporate travel and hospitality management platform enabling seamless booking, policy-governed approval workflows, multi-supplier inventory access, and intelligent automation for corporate travel administrators, managers, and employees — targeting enterprise and mid-market B2B buyers managing travel spend at scale.
What we built
Tripare is a full-stack corporate travel management platform built across 29 active weeks by an 18-person Antino team. The system encompasses:
- a multi-supplier flight and hotel booking engine with real-time polling, Redis caching, and PostGIS location data
- a configurable travel policy engine with per-tier rules for flight class, advance booking days, and hotel price caps
- a multi-level (L1/L2) approval workflow with auto-approve thresholds, escalation, and policy violation flagging
- a JWT-based delegation and Executive Assistant management system
- a wallet/ledger budget management system with fund holding, reconciliation, low-balance alerts, and department-level spend tracking
- a CFO-facing analytics dashboard with materialized-view-backed department spend aggregation, policy compliance charts, and savings metrics
- a complete React Native mobile app (iOS + Android) with push notifications, deep linking, OTA updates, and EAS CI/CD
- supplier integrations with Tripjack (inventory), Zoho (invoicing/refunds), and HRMS (employee sync)
- guest booking and CSV bulk invite flows
- Special Service Requests (SSR) and search-to-review change detection; and
- a per-org feature flag and app version management system.
The full web platform is live in production with flight/hotel booking (domestic + international + multi-city), multi-level approval workflows, delegation, budget/wallet management, markup/GST/convenience fee pricing, analytics dashboard, guest booking, SSR, HRMS integration, and Zoho invoicing. The React Native mobile app (iOS + Android) is live on Play Store and App Store with push notifications, deep linking, OTA update channels, and full booking parity with web.
