Travel Commerce Marketplace
Designing a High-Ticket Multi-Vendor Travel Portal with Regional Currency Settlements.
The Challenge
Multi-vendor travel marketplaces process massive transaction amounts while distributing payouts across multiple regional airlines and hotel partners. AeroTravel needed an automated currency settlement ledger and transaction payout system with multi-region tax matching rules.
The Solution
We built the Travel Commerce Marketplace on C# ASP.NET Core 8 and React. We implemented Adyen Split Payouts API to automate ledger balances across vendor accounts, processing commissions dynamically. The microservices communicate via RabbitMQ queues to compile reports asynchronously.
The Process & Implementation
We optimized query structures using Dapper over a PostgreSQL cluster, caching hot inventory categories in Redis. We set up Azure Functions to run daily ledger settlements and tax checks. The platform is monitored continuously using Datadog dashboard metrics.
The Results Delivered
The AeroTravel marketplace launched successfully, automating millions in monthly payments. Regional vendors receive payouts autonomously with zero calculation issues.
Business & System Impact
- Automated Split Payouts: Adyen integration routes vendor payouts and platform commissions instantly.
- Sub-2 Second Search: Distributed caching maps thousands of travel packages with fast responses.
- Multi-Region Settlement: Resolves currency conversions across 12 distinct regional bank APIs.
