Case Study: Redbus achieves fast B2B e-invoicing compliance with Complyance

How Redbus Enabled Fast B2B E-Invoicing with API First Middleware for Internet Brands

Redbus, a global digital platform for bus ticketing, faced a significant challenge in achieving LHDN e-invoicing compliance for its B2B invoices in Malaysia. Their custom, proprietary billing system made schema alignment and real-time validation complex. They partnered with Complyance to integrate an API-first middleware solution that could meet their strict latency and architectural requirements.

Complyance implemented a REST API-based middleware that converted Redbus’s internal invoice data into LHDN-compliant JSON payloads without requiring changes to their existing billing code. This solution enabled Redbus to achieve full compliance in under three weeks. The scalable architecture now processes over 10 million invoices annually and can be reused as Redbus expands into other Southeast Asian markets.
