Which Payroll Software Is Best for SMEs? Comparing 5 Systems

Some of the leading payroll software solutions for SMEs in Thailand in 2024 include HumanSoft, Wave Payroll, Xero Payroll, Paychex Flex, and Zoho Payroll.

 

According to the source article, HumanSoft is positioned as particularly suitable for Thai SMEs because it supports Thai labor requirements as well as withholding tax and Social Security calculations within a single system.

 

What Is an SME, and Why Should SMEs Use Payroll Software?

SME stands for Small and Medium Enterprises, referring to businesses that are relatively small or medium in size.

 

SME classification is generally based on factors such as:

• Number of employees
• Annual revenue
• Asset value

 

The specific criteria may vary according to the requirements established by government agencies.

SMEs cover many types of businesses, including retail stores, service businesses, small factories, online businesses, startups, and family-owned businesses. They also tend to have less complex organizational structures and fewer employees than large enterprises.

 

One of the most common challenges faced by HR teams in SMEs is calculating payroll using Excel. This can be time-consuming, prone to errors, and difficult to keep aligned with changing labor requirements.

 

Payroll software can help address these challenges by:

• Automatically calculating salaries and OT to reduce errors from manual data entry
• Calculating withholding tax and Social Security contributions
• Automatically generating payslips and 50 Tawi withholding tax certificates
• Managing leave, holidays, and employee benefits in one place

 

Criteria for Choosing Good Payroll Software for SMEs

Good payroll software for SMEs should help reduce HR workload, calculate payroll according to company-specific conditions, and support future business growth.

 

Before making a decision, organizations should consider the following factors:

• Comprehensive payroll calculation: The system should support base salary, OT, bonuses, commissions, earnings, and deductions.
• Support for Thai tax and Social Security: It should help organize payroll-related tax and Social Security information systematically.
• Integration with attendance, leave, and OT data: This reduces the need to retrieve data from multiple files and repeatedly enter the same information.
• Ease of use: Both HR teams and employees should be able to learn and use the system without unnecessarily complicated steps.
• E-Slip and Employee Self-Service: Employees should be able to view payslips, leave information, and their own data.
• Access permissions: The organization should be able to control access to payroll and personal employee information.
• Reports and historical audit capabilities: HR should be able to verify information before and after closing a payroll cycle.
• After-sales service and support: The provider should assist with configuration, troubleshooting, and payroll-related questions.
• Appropriate pricing: Organizations should consider the system fee, implementation costs, additional modules, and potential future expenses.

How Should Thai SMEs Choose a Payroll System?

For Thai SMEs, simply having a system that can “calculate payroll” may not be enough.

Each payroll cycle may involve multiple types of information, including:

 

• Working hours
• Work shifts
• OT
• Leave
• Earnings
• Deductions
• Taxes
• Social Security contributions

 

HumanSoft connects this information from the HR system directly to payroll calculations.

This helps HR teams reduce the need to transfer information between multiple files and allows them to review relevant data in one system before closing each payroll cycle.

Each payroll software solution for SMEs has different strengths, whether in payroll calculation, accounting integration, HR functionality, or payroll support across different markets.

 

Before choosing a system, organizations should consider:

• Required features

• Budget

These factors should be evaluated according to the organization’s actual business model.

For Thai SMEs, it is particularly useful to choose software that reduces manual work and connects data from Time Attendance, leave, and OT through to Payroll. This can help HR teams work more efficiently and systematically.
