How we are funded
You never pay us. Vendors do.
Choosing your HR software with HRStack is free, start to finish — never a cost to you, and never a markup on your price. Deeper advisory is optional and separately paid; the selection process itself always is free.
See exactly how we're fundedWe earn a referral fee
Paid by the vendor you choose, never by you — and never as a markup on your price.
Vendors can't influence your scores
Your evaluation scores come from your requirements. Vendors can't see them.
How we're paid is public
The funding model is written out in full, before you start — no incentive you have to guess at.
Why teams trust it
A methodology buyers can explain to the rest of the business.
HRStack.ai is designed to replace vague market noise with a process that can stand up to stakeholder challenge, procurement scrutiny, and implementation reality.
Structured
Maturity findings, requirements, must-have criteria, and advisory reasoning are made explicit so decisions can be defended internally.
Buyer-side
The process is designed around buying-team realities: alignment, governance, demos, and implementation risk.
Expert Advisory
Two entry points: maturity improvement or requirements readiness.
HR Tech Diagnostics
Understand where you are before committing to change.
Implementation Advisory
Client-side advisory throughout the implementation.
The problem we're solving
Most HR teams start with a “top 10 HRMS” blog, a few vendor demos, and a gut call dressed up in a spreadsheet. The research is scattered, the comparisons aren’t yours, and the decision rests on whoever demoed best.
We built something structured instead.

How to Evaluate HR Software: A Buyer's Guide
HR software evaluation is a process that most organisations approach backwards — starting with demos and ending with a decision that was half-made in the first vendor call. This guide covers how to structure the evaluation so the decision is driven by requirements, not by whoever presented best.
HRMS vs HRIS: Understanding the Difference
HRMS and HRIS are frequently used interchangeably, but they describe different scopes of functionality. Understanding the distinction helps buying teams align terminology with requirements — and avoid selecting a system that covers half of what they need.
HR Maturity: What It Means and Why It Shapes Your System Selection
HR maturity is one of the most consequential — and most ignored — factors in HRMS selection. Understanding where your HR function sits on the maturity spectrum changes which vendors are viable, which features are premature, and which implementation paths are realistic.
How to Build an HRMS Vendor Shortlist
Most HRMS shortlists fail before the first demo. This guide explains how to build a structured, defensible vendor shortlist based on organisational context rather than brand familiarity or seeded review rankings.
