HR Tech Stack: The Tools Every Organisation Should Have

There are thousands of HR tools. What should you pick first, and how do enterprise and startup needs differ? A practical stack guide for Thailand in 2026.

HR teams at Thai companies of every size in 2026 are asking the same question: which HR tools should we choose, and where do we start? In a market with hundreds of tools, investing in the wrong direction wastes both budget and time. A good HR Tech Stack is not about having every tool. It is about choosing tools that fit the specific needs of your company's stage and that connect with each other.

The 5 Layers of an HR Tech Stack

Grouping tools into layers helps you see the big picture.

Main Layers

1. Core HRIS that stores employee data, payroll and leave
2. Talent Acquisition: ATS and sourcing tools
3. Performance and Learning: evaluation and development
4. Engagement and Wellbeing: surveys and feedback
5. Analytics and AI that use data across every layer

Investing in this order gives the company a foundation before building advanced capabilities. Companies that skip the lower layers often invest in the upper layers and then cannot use them because there is no data to support them.

Stack for a Startup of 50 to 100 People

Keeping it to the essentials

Tools You Should Have

• An HRIS such as Humanica or Rippling for payroll and core data
• An ATS such as Workable or Greenhouse Lite
• A company-wide collaboration tool such as Slack or Teams
• A survey tool such as Lattice basic or Officevibe
• Structured document storage such as Notion

An investment of 50,000 to 100,000 baht per month gets a stack that covers the basics. Companies of this size do not need to invest more than this.

Stack for a Mid-Size Company of 100 to 500 People

The necessary expansion

Additions to the Startup Stack

• Performance management such as Lattice full or Culture Amp
• A learning platform such as Coursera Business or LinkedIn Learning
• An onboarding tool that structures the first 30/60/90 days
• A recruiting marketing tool such as TeamTailor
• An HR analytics dashboard that combines data from different tools

An investment of 150,000 to 300,000 baht per month gets a stack that scales to support growth.

Stack for an Enterprise of 500+ People

Enterprise-grade investment

Additions to the Mid-Size Stack

• An enterprise HRIS such as Workday or SuccessFactors
• A Total Rewards platform such as Beqom
• People Analytics such as Visier
• Talent intelligence such as Eightfold or Phenom
• An AI assistant such as Microsoft Copilot for HR
• Custom integration between every system

An enterprise stack starts at 500,000 baht per month and up. The ROI must be clear; do not buy just because others have it.

A good HR Tech Stack is not measured by the number of tools but by how smoothly data flows between them.

Choosing a Compliant Vendor

Selection criteria

Questions to Ask Vendors

• PDPA compliance in Thailand
• Which region the data resides in
• Integration with other tools: is there an API?
• Support for the Thai language and Thai context
• A pricing model that scales with headcount
• Implementation timeline and the resources required
• References from companies of the same size in Thailand

Paying 20 to 30 percent more for a vendor with strong compliance is better value than taking on the risk. Read AI Compliance for HR

Integration Matters Most

A tool that is good and cheap but does not integrate has no value.

Integrations You Must Have

• HRIS as the source of truth, with employee data flowing out to other tools
• ATS to HRIS, so new hire data does not need to be re-entered
• Performance to comp, so review results are tied to adjustments
• Learning to skill inventory, to track skills gained
• Engagement to action, triggering workflows when there is an alert

Integration accounts for 30 to 40 percent of the tech stack budget, which many companies underestimate.

Connecting to Strategy

The HR tech stack is a tool for the bigger strategy.
