Abstract
Modern payroll automation systems increasingly rely on distributed, event-driven architectures to support scalability, organizational decoupling, and multi-jurisdictional complexity. While such architectures enable horizontal scaling and operational flexibility, they introduce fundamental challenges in event sequencing and concurrency control. Payroll workflows involve cumulative thresholds, legally binding financial outputs, retroactive adjustments, and cross-entity dependencies that require deterministic ordering and strict isolation. Delivery uncertainty, partition rebalancing, duplicate messages, and concurrent processing can compromise financial integrity if not addressed systematically. This paper examines event sequencing and concurrency control in distributed payroll automation systems from an algorithmic and architectural perspective. It proposes identity-based partitioning, deterministic state transitions, isolation boundaries, replay-safe event handling, and coordinated sequencing for cross-entity operations. By integrating distributed systems theory with payroll-specific financial invariants, the study advances a design framework that preserves correctness under parallel execution and infrastructure variability. The resulting model supports audit-grade traceability, temporal consistency, and high-volume enterprise payroll processing without reliance on global locking or centralized transaction coordination.
