Software that manages the employee lifecycle — recruitment, onboarding, attendance, leave, performance and records — so HR teams work from one accurate employee record instead of spreadsheets and separate tools.

How much does HR software development cost in Korea?

Cost depends on the number of employees, the modules included and the payroll and accounting integrations required. We provide a detailed estimate after discovery, and our software development cost calculator gives an initial range.

Can you build an applicant tracking system?

Yes. We build job posting, application intake, candidate pipelines, interview scheduling and feedback in one workflow, connected to onboarding.

Can the system handle Korean working-hour and leave rules?

Yes. Working-hour tracking, overtime, leave accrual and approval chains are configured around Korean practice and your own policies. Final policy and legal decisions remain with your HR and legal teams.

Can it connect to our payroll system?

Yes. We integrate attendance and leave data with your payroll and accounting systems so data is entered once and reconciliation is reduced.

How do you protect applicant and employee data?

Role-based access, encryption in transit and at rest, and audit logs are built in, and data handling is designed around the Personal Information Protection Act. Compliance decisions remain with your legal team.

Can you build a platform for a staffing or recruitment agency?

Yes. We build candidate databases, client job orders, placements and reporting for staffing and recruitment firms.

Can AI help with recruitment?

AI can summarise applications, structure candidate information and support search. It assists recruiters, and hiring decisions stay with people, which also keeps the process fair and explainable.

Do you build an employee mobile app?

Yes. We build iOS and Android self-service apps for leave, attendance and company notices from a single codebase.

Can you migrate data from our spreadsheets or current HR tool?

Yes. We map and migrate employee, leave and attendance data, validate it with your HR team, and run the old and new systems in parallel when needed.

How long does development take?

Typically 10 to 16 weeks for a first production module, longer for a full platform with payroll integration and mobile apps.

Who owns the source code?

You do. The codebase, infrastructure and documentation are yours, not licensed to you.

Overview

HR and Recruitment Overview

Aixo Lab builds HR and recruitment software for growing companies, staffing firms and HR teams in Korea — applicant tracking, onboarding, attendance, leave, payroll integration and workforce analytics in one employee record.

One Employee Record
Candidates become employees without re-entering data, so recruitment, onboarding and HR share a single, accurate record.
Built for Korean Working Practices
Working-hour tracking, leave rules and approval chains are configured around how Korean companies actually operate.
Sensitive Data, Handled Carefully
Applicant and employee data is access-controlled and logged, designed around personal-data protection requirements.

What's Included

Everything under one roof

Everything included in this engagement, from architecture to long-term support — one team, one system.

Job postings, applications and candidate pipelines tracked in one view, visible to hiring managers.

Candidate Sourcing and Talent Pool

A searchable talent database that keeps past applicants and referrals ready for new roles.

Interview Scheduling

Interview coordination with calendars, reminders and structured feedback forms.

Checklists, documents and tasks that bring a new hire from signed offer to first day without chasing.

Employee Directory

Every employee, role and reporting line in one searchable directory and organisation chart.

Attendance and Working Hours

Check-in, shift and overtime tracking that supports working-hour management.

Leave Management

Leave requests, balances and approvals handled in the app instead of an inbox.

Payroll Integration

Attendance and leave data passed to your payroll system, reducing manual reconciliation.

Performance Reviews

Review cycles, goals and feedback collected in a structured, trackable process.

Contracts and e-Signature

Employment contracts and HR documents generated, signed and stored digitally.

Mobile access to leave, attendance, payslip links and company notices.

Why Aixo Lab

Why HR Teams and Staffing Firms Choose Aixo Lab

We Model How Korean Companies Work
Working-hour rules, leave policies and approval chains follow Korean practice and your own policies, instead of a generic overseas template.
We Protect Candidate and Employee Data
Role-based access, encryption and audit logs are built in, designed around the Personal Information Protection Act, because HR data is among the most sensitive a company holds.
We Integrate Before We Replace
Payroll, accounting and existing HR tools stay in place; we connect to them so the payroll cycle is never put at risk.
We Reduce Administration Without Adding Steps
Automation targets the repetitive work — reminders, approvals, document generation — so HR spends time on people rather than process.
