About Bonhams

Bonhams is one of the world’s largest and most renowned auction houses for fine art, antiques, motorcars, and jewelry. Headquartered in the UK, the company has a global footprint and employs staff across multiple geographies.

To streamline internal travel logistics and expense management, Bonhams sought a modern, mobile-first solution that could serve employees, supervisors, and admin stakeholders—empowering them with a unified system for booking, approvals, and expense claims.

Challenges

Performance or Efficiency Issues

  • Manual, email-driven travel and expense workflows were time-consuming and error-prone.
  • Lack of central tracking caused delays and reduced employee productivity.

Access/Security Gaps

  • No secure, centralized role-based system for managing sensitive travel and financial data.

Scalability or Maintainability Bottlenecks

  • Previous processes couldn’t scale across global teams or accommodate growing travel needs.

Integration or Data Flow Issues

  • Integrating real-time data from third-party providers (flights, hotels, weather) posed reliability
    and performance challenges.

UI/UX or Workflow Limitations

  • Employees lacked an intuitive interface to manage bookings and expense claims on the go.

Solution: Challenge → Solution → Result Mapping

Challenge Solution Result
No centralized, secure platform for travel & expense workflows. Developed a cross-platform mobile (Flutter) and web (ReactJS) solution with a Node.js backend, enabling role-based login, travel planning, approval workflows, and expense tracking. 80% reduction in manual coordination; faster turnaround on travel approvals.
Real-time third-party API data was inconsistent and prone to failures. Implemented robust retry logic, fallback providers, and monitoring for third-party API calls (hotels, flights, weather). Increased reliability and user trust in booking workflows.
Security risks in token and API key management. Secured API keys using environment variables and centralized token handling through a secure API gateway. Improved system integrity and compliance with enterprise IT standards.
No unified admin control or employee oversight. Built an admin dashboard with full visibility over users, approval hierarchies, travel statuses, and reporting. Enhanced governance and transparency for finance and HR teams.
