Payroll Cycle — Configurable Pay Cycles

  • Strengths
  • Supports every standard payroll cycle format
  • Supports special installments (Bonus / Backpay / Commission)
  • Add unlimited special installments
  • Calculate OT in a separate installment
  • Calculate working time in a separate installment
  • Split pay into up to 4 installments per month
  • Calculation method: "final installment = full amount − previous installments"
  • Calculation method: "full amount = sum of all installments"
  • Set your own installment start/end dates, or let the system calculate them
  • Use Case
  • A company uses a 26-25 cycle / a restaurant uses 1-31 / a factory uses 21-20 → all can be configured
  • Year-end bonus is paid as a "special installment" separate from salary for clarity
  • A company has weekly commission plus a monthly attendance bonus → set up as unlimited separate installments
  • Payroll must close but OT isn't approved yet → OT can be split into a separate installment paid next cycle
  • Employee deduction installments, such as absence-tardiness-leave, can be separated from the main salary installment
  • The company wants to help employees manage cash flow, e.g. paying on the 15th/30th/7th/22nd of each month
  • The first installment pays 10,000 → the system automatically calculates the remaining amount for the final installment
  • Each installment is independent, e.g. a 20,000 salary installment plus a 2,000 OT installment
  • HR selects "let the system decide," and the cycle automatically shifts the following month

Tax / SSO / PVD — Accurate Tax, Insurance & Fund Calculations

  • Strengths
  • Calculates PND1 tax by estimating annual income
  • Supports section 40(2) income
  • Fixed-amount tax
  • Percentage-of-income tax
  • PND3 tax combined with salary
  • PND3 tax separate from salary
  • Supports all standard tax deductions
  • Social security supports 6 formats
  • PVD supports up to 3 funds
  • Tiered percentage deductions/contributions based on salary range
  • Instantly generate fund filing files
  • Choose which items count toward TAX/SSO/PVD
  • Choose whether to show/hide items on the payslip
  • Use Case
  • For employees with fluctuating income → the system recalculates tax every month, more accurate than a "fixed" method
  • Freelance or special income → the correct tax type is applied instantly
  • Some executives choose a fixed 5,000-baht monthly tax deduction instead of formula-based calculation
  • A 50,000-baht commission payment with 5% tax withheld = 2,500 baht
  • Some companies need to combine other income with salary for a single tax filing
  • Meal/cost-of-living allowances can be billed for tax separately from salary
  • An employee gets married, has children, or holds RMF/SSF → all entered in the system without manual calculation
  • A company has multiple employee types, e.g. Section 33, Section 39, fixed base, actual base
  • A large company with multiple PVD funds, e.g. old and new funds → can be split by eligibility
  • Employees earning <20,000 = 5%
    employees earning >20,000 = 7%
  • HR no longer needs to manually organize Excel files
  • Commission is taxable, but a "fuel allowance" is not
  • Special bonus items are shown / phone allowance is hidden

Automatic Earnings — Conditional Automatic Payments

  • Strengths
  • Single-tier conditional attendance bonus
  • Multi-tier attendance bonus — resets if conditions are broken
  • Conditional daily allowance

  • Use Case
  • No absences, no tardiness, no more than 1 leave → earns 800 baht

  • An employee must fully clock in and out → earns a 50 baht/day allowance
  • A calculated 199.75 baht → rounded to 200 baht
