Business Situation

An HR team running monthly payroll under Indonesian statutory rules — PPh 21 income tax, BPJS contributions, and UMR minimum-wage floors — with employee data, salary components, and the rules themselves maintained in spreadsheets.

Operational Challenge

Every run meant applying those rules by hand. The calculation took days, and it could not be audited afterwards because the working was formulas rather than records. Any change to a statutory rule or a salary component meant redoing the month, and the close date depended on one or two specific people being available.

Solution

Payroll Agent automates payroll calculation, tax compliance, and salary disbursement. Employee data, salary components, and statutory rules live in one system. A pipeline of four specialized agents validates inputs, computes PPh 21, BPJS, and UMR-compliant salaries, and produces disbursement-ready output.

Business Impact

A full payroll run completes in about 13 seconds instead of days. Every figure has a record behind it, so a question about a payslip is answered by looking it up rather than by rebuilding the calculation. Rule changes are applied once, centrally, instead of being re-entered across a spreadsheet.

Workflow

Features

Architecture

Built on Laravel with Blade views, the system models the full payroll domain — employees, components, deductions, statutory rules — as first-class records rather than spreadsheet formulas. The payroll run is a staged pipeline where each agent owns one concern (input validation, gross-to-net calculation, statutory compliance, disbursement preparation), which keeps the tax logic auditable and each stage independently testable.
