Building Microservices for Scalable HRMS Payroll Processing

Batch Processing Architecture

Calculating monthly payroll for an enterprise with 10,000 employees involves evaluating hundreds of dynamic parameters: variable overtime rules, tax slab adjustments, provident fund contributions, loan deductions, and performance incentives.

PeopleSpan offloads batch calculations to isolated worker containers orchestrated via distributed message queues. Each department is processed in parallel shards, slashing total runtime from hours down to just minutes.
