Custom HR software development and HRMS integration workflow

HR-Tech Development & Integration

Custom HR Software Development & Integration

Bespoke HR software, HRMS/HRIS, payroll and ATS integration, and audit-ready AI automation — built by a team with eleven years in the domain and HR products of its own.

Most HR teams don't lack software — they're drowning in it. Payroll in one tool, attendance in another, an ATS, and a spreadsheet quietly holding it all together. Gunadhya is a custom HR software development and integration company that makes those systems behave as one. We build bespoke HR tools, integrate HRMS, HRIS, payroll and ATS platforms — including the ones with closed or hostile APIs that most firms avoid — and add AI automation that's built to survive a compliance audit. Eleven years in, with HR products of our own (WorkNXL, TimeTango), we know this domain from the inside, not from a brochure.

What we build & integrate

Custom HR software development

Built around your workflow, not a vendor's template. The HR tool you'd buy if it existed.

HRMS / HRIS integration

Make your core HR systems share one source of truth, so data stops being re-keyed between tools.

Payroll & attendance integration

Connect payroll, biometric devices and legacy attendance tools into one clean pipeline.

ATS / recruitment platform development

Your own hiring platform — job posts, candidate matching, interview workflows — your way.

HR workflow automation

Onboarding, approvals, exits and document generation, automated end to end.

AI HR automation (audit-ready)

Resume screening, onboarding orchestration and Tier-1 employee Q&A — wired into your systems, with decision logging so every action is explainable.

Legacy migration

Off spreadsheets and disconnected point tools, onto something that holds as you grow.

Compliance-aware payroll

India Labour Codes-aware logic and statutory outputs (Form 24Q, Form 16, EPFO/ESIC) produced without manual rework each month.

Who we help

SMEs

Running HR on spreadsheets and a patchwork of point tools that don't talk to each other.

Recruitment & Staffing Firms

That want to own their platform instead of renting someone else's.

Complex Enterprise Setups

With a closed-API system or an odd tool combination that no off-the-shelf HR suite supports.

How we work

Map the breaks.

We sit with your HR and ops people and find exactly where data is re-keyed, lost, or delayed. No project starts until the breakage is named.

Build vs. buy, honestly.

If an off-the-shelf tool fits, we'll say so — even though it means a smaller project for us. We only build what's genuinely worth building.

Integrate, then automate.

Systems share one source of truth first; AI and automation go on top of clean, connected data — never on top of chaos.

Make it auditable.

Decision logging, statutory outputs and a maintainable codebase, so what we ship survives both an inspection and your next hire.

Frequently Asked Questions

Q: Should we build custom HR software or buy an off-the-shelf tool?

Buy if your process is standard and you can live within a tool's limits. Build if your workflow is your edge, or if no single tool fits your odd combination of systems. We'll tell you honestly which applies — even when the answer is "buy."

Q: Can you integrate HR systems that don't have an open API?

Yes — it's one of our core strengths. We've built reliable integrations around closed and hostile APIs that most firms walk away from.

Q: Can you add AI to our existing HR systems?

Yes. AI agents only work when wired into your HRIS, payroll and knowledge base. We do that integration and add an audit-ready AI layer — screening, onboarding orchestration, Tier-1 employee Q&A — on top.

Q: Can you make our payroll compliant with India's new Labour Codes?

We build the custom logic and integrations so your existing systems produce compliant, inspection-ready records and statutory reports (Form 24Q, Form 16, EPFO/ESIC) — without manual rework each month.

Q: We're an SME on spreadsheets. Is this overkill for us?

No — SMEs are exactly who we build for. We start small: connect what you already have, kill the worst manual step, then grow from there. You don't need an enterprise budget to stop re-keying data.

Q: Will we be locked into you afterwards?

No. We hand over clean, documented, maintainable code. The point is to make your HR stack work — not to make you dependent on us.
