What Payroll Software Should You Use for Twice-Monthly Pay?

Companies that pay employees twice a month should choose payroll software that supports split payments, configurable calculation periods and pay dates, and checks of both individual payments and monthly totals. This helps HR manage salaries, additional earnings, and deductions in line with company policies.

 

Paying salaries twice a month may seem as simple as dividing a salary in half. However, overtime (OT), commissions, employees starting partway through the month, and deductions can result in different amounts for each payment. Suitable software should therefore help HR identify the data behind each calculation and track how much has already been paid.

 

What Should You Define Before Introducing Twice-Monthly Pay?

Before choosing software, companies should clearly define their payroll process. Even companies with the same pay dates may use different calculation methods.

 

How Does a Calculation Period Differ from a Pay Date?  

A calculation period is the date range of the data used to calculate pay, while a pay date is the day the company transfers money to employees. For example, data from the 1st–15th may be used for a payment on the 20th.

HR should specify the calculation period, data cutoff date, and payment date, and check whether the OT period matches the payroll period. This makes it easier to choose software that can be configured for actual operations.

 

How Is the First Payment Calculated, and What Is the Second Based On?

Companies should clearly define their calculation method, for example:

• Calculate each period separately, then combine the results into a monthly total.

• Calculate the full monthly amount, then subtract the first payment to determine the final payment.

These methods follow different calculation sequences. Ask the provider to demonstrate them using your company's sample data before making a decision.

 

Which Payment Includes Each Earning and Deduction?

Specify which payment should include OT, commissions, allowances, and company deductions. Statutory items must be configured in accordance with the applicable rules.

Copying data from the first period to the second without checking it may cause earnings or deductions to be counted twice.

 

What Features Should Payroll Software for Twice-Monthly Pay Include?

Choose software that manages payment periods and checks monthly totals in one system. Use the following table as a checklist when speaking with providers.

 

1. Support for Connected Split Payments

When a provider says its software supports multiple payment cycles, ask how each payment connects to the monthly total, especially when earnings are changed after the first payment.

Seeing both individual payment amounts and the overall total helps HR check whether the amount already paid plus the amount still to be paid is correct.

 

2. Traceable Pay Calculations

When an employee asks, “Why is my pay different this time?” HR should be able to see whether the difference comes from salary, OT, additional earnings, or deductions.

Software that clearly displays each component of pay makes it easier to check the figures and explain them to employees.

 

3. Support for Real Workplace Scenarios

If your company has employees joining, leaving, or receiving salary adjustments during the month, test these scenarios as well. A demonstration based only on a fixed monthly salary may not cover everyday payroll needs.

 

Example: Checking Two Payroll Payments

Suppose a company calculates net pay for the full month, then subtracts the first payment. The figures are as follows:

 

Second payment = Monthly net pay − First payment already made

 

Therefore, 25,000 − 12,000 = THB 13,000. The two payments must add up to THB 25,000.

This example illustrates how to check payment totals only. The THB 1,000 deduction is hypothetical; it is not an example of tax or contribution calculations, and this formula does not apply to every company.

 

What Scenarios Should You Test Before Choosing Payroll Software?

Prepare anonymized sample data and ask the provider to demonstrate at least these five scenarios:

1. Employee working a full month: Check that both payments add up to monthly net pay.

2. Employee starting mid-month: Check the date range and calculation basis.

3. OT or additional earnings: Check that each item is included in the intended payment.

4. Multiple deduction types: Check the calculation methods and accumulated totals to prevent duplicate or missing amounts.

5. Changes after the first payment: Check how the system shows differences and handles the next payment.

 

In addition to checking calculations, ask about data migration, initial setup, training, and support channels for issues that arise before payday.

 

How Does HumanSoft Support Twice-Monthly Payroll?

HumanSoft payroll software supports up to four payment periods per payroll month, with configurable payment cycles and employee calculation periods. This makes it an option for companies that want to pay employees twice a month.

The system offers two split-payment calculation methods:

• Final payment = Full-month amount − Sum of previous split payments, giving the remaining amount after earlier payments are deducted.

• Full-month amount = Sum of split payments, calculating each payment separately before combining them into a monthly total.

To change the [split-payment calculation method], contact the HumanSoft team to make the change.

 

See the [steps for setting up split payments in HumanSoft] for a step-by-step guide, from setting the number of payment periods and each period's data cutoff date to selecting employees who receive split payments.

 

HR can select an employee to review on the Individual Payroll Calculation page. The system displays tabs for periods containing that employee's data, based on the configuration and available payslips, helping HR check each employee's information before closing payroll.

Before getting started, tell the team how your company defines calculation periods, when payments are made, and which payments include each earning and deduction. This helps determine a configuration that matches your operations.

 

Choose Software That Matches Your Company's Payroll Process

Companies paying employees twice a month should choose payroll software that supports split payments, checks each payment, and connects the figures to the monthly total. Before going live, test mid-month starters, additional earnings, and changes made after the first payment.

If you are considering HumanSoft, you can register for guidance from the team and share your company's payment structure so the team can assess the configuration needed for your payroll process.

 

Frequently Asked Questions About Twice-Monthly Payroll

Q: Must Both Payments Be Equal When Salaries Are Paid Twice a Month?

A: The amounts may differ depending on the calculation method and the items included in each payment. For example, the second payment may include OT or additional earnings. Companies should explain the rules clearly to employees.

 

Q: Which Payment Should Include Social Security Deductions?

A: Under Section 47 of the Social Security Act, employers must deduct contributions from wages each time wages are paid. Companies making two payments should therefore deduct contributions from each payment. The monthly total must be calculated from the full month's wages and must not exceed the statutory ceiling.

 

Q: What Information Is Needed to Switch from Monthly to Twice-Monthly Pay?

A: Prepare the calculation periods, pay dates, employee groups, calculation method for each payment, earnings and deductions, and any amounts already paid in the transition month to prevent missing or duplicate payments. Review the relevant employment terms before changing the policy.

 

Q: How Is Pay Calculated When an Employee Resigns Mid-Period?

A: Calculate pay based on the actual days worked in that period, then compare it with amounts already paid in the same month to avoid overpayment or underpayment.
