Recovering 15% Revenue via Idempotent State Machines

Eliminated silent payment failures and recovered 15% of revenue by implementing idempotent state machines for deterministic payment control.

Overview

Payment systems often fail silently due to duplicate transactions during retries and inconsistent payment states, leading to revenue leakage.

Approach

A state-driven payment orchestration system that enforces correctness at every step using a deterministic state flow: DRAFT → SUBMITTED → APPROVED → PROCESSING → PAID → FAILED.

Implemented idempotent processing and idempotency keys to prevent duplicate payments during retries, alongside a role-based approval workflow.
