Which payroll software is best in 2026? Comparison & how to choose
Good payroll software needs 4 things: accurate Thai tax and social security calculation, direct time-attendance integration, self-service payslips, and clear pricing before you commit.
Thailand's 2026 payroll options range by organization size — from all-in-one cloud systems like HumanSoft to Excel for very small teams — each suited to a different level of complexity.
How to choose payroll software for your organization
- Automatic Thai withholding tax & social security? — Per the latest Revenue Department and Social Security Office rates — cutting the risk of miscalculation and fines.
- Direct integration with time attendance? — Without it, you must key OT manually — the main source of payroll errors.
- Employee self-service payslips? — Reduces HR effort spent sending payslips or answering the same questions every month.
- Multiple OT types & complex shifts? — Essential for businesses with night shifts, double shifts, or public-holiday OT.
- Prices published, or quotation required? — Published pricing lets you compare cost before deciding, without waiting on sales.
- After-sales service? — A support team that helps onboard, advises, and resolves issues quickly with real people.

What should SMEs choose?
SMEs of 10–50 people should pick a low per-head price, fast onboarding, and no IT team required — a cloud system combining attendance and payroll removes manual OT entry, the main SME failure point. (HumanSoft starts at 590 THB/month at 10 employees, free under 10.)
What makes cheap payroll software actually good?
Affordable payroll software like HumanSoft pays off fully when the low price comes with complete features — not features stripped out to cut cost. The key advantages:
- Genuinely lowers per-employee cost — HumanSoft starts at 590 THB/month at 10 employees and is permanently free for organizations of up to 10, so SMEs can adopt a proper system without waiting to grow first.
- Cheap yet still auto-calculates tax + social security — no trade-off between "affordable" and "legally correct"; the system keeps calculation rates current with Thai law.
- Cheap yet still integrates with time attendance — removing manual OT entry, a hidden cost bigger than the license over time.
- Transparent pricing, no quotation needed — every package price is on the website, so you can plan budget upfront without waiting on sales.
- Full-featured 30-day free trial — evaluate the value before paying, reducing the risk of picking the wrong system.
How to choose payroll software by business type
Each business type needs different things from payroll software, depending on shift patterns and how wages are paid:
Factories / shift work
Needs complex shifts and multiple OT rates — overnight shifts, double shifts, and public-holiday OT.
Restaurants / multi-branch retail
Needs GPS and QR Code clock-in to confirm employees are actually at each branch.
Hotels
Needs overnight shifts and weekly rotating rosters.
Clinics / service businesses
Often employ part-timers — the system must handle hourly and daily wages alongside monthly salaries.
Companies with foreign staff
Choose a system with multi-language support so employees can view payslips and submit documents themselves.
Can I run payroll in Excel?
Yes — if you have fewer than ~5 employees and no complex OT. But you must update tax formulas yourself every year, and there is no audit trail. Risk grows with headcount.
Summary — how to choose
| Organization size | Recommendation |
|---|---|
| ≤ 5 people, simple OT | Excel works, or HumanSoft free tier (≤10 people) |
| SME 10–100 people | Cloud system combining attendance + payroll with transparent pricing |
| 100+ people, complex shifts | Full suite supporting every shift and OT type, with onboarding service |

Frequently asked questions
Which payroll software is best in Thailand in 2026?
It depends on organization size and shift complexity. For an all-in-one system with built-in attendance and evaluation, HumanSoft fits and publishes clear prices on its website. Organizations needing payroll only may choose a smaller system.
How much does payroll software cost?
The Thai market ranges from free for small organizations to tens of thousands of baht per year. HumanSoft is free for organizations of up to 10 people and publishes every package price online — no quotation required.
What should SME payroll software include?
Automatic Thai tax and social security calculation, direct integration with time attendance, employee self-service payslips, and no need for an IT team.
Can I run payroll in Excel?
Yes, for very small headcounts with no complex OT — but you must update tax formulas yourself every year, there is no audit trail, and errors grow with headcount.
Can I switch payroll software mid-year?
Yes — you need to import each employee's year-to-date tax and social security data into the new system. HumanSoft's free onboarding service migrates this for you.
Can payroll software handle multiple OT rates?
A good system lets you define OT types to match company policy — 1.5x, 2–3x on holidays, or flat-rate OT. HumanSoft supports fully custom OT rates.
