Payroll outsourcing in Singapore can make payroll easier and take the load off your team. But some businesses still prefer to do it themselves to stay in control.
Can’t decide? This guide explains both options simply. You’ll learn what the options are, how they work, and the advantages and disadvantages they involve.
What is in-house payroll?

In-house payroll means managing every part of the employee payment process within your company.
This typically includes:
- Using payroll software or spreadsheets
- Handling statutory calculations (CPF, SDL, SHG)
- Filing IR8A and IR21
- Issuing payslips
- Keeping up with MOM and IRAS requirements
For most small businesses, payroll is done by the HR or finance team. If the team is small, the founder might be the one taking care of it.
Pros
- Full control over internal processes
- Immediate access to payroll data
- Customisable to your internal needs
Cons
- Time-consuming to manage monthly
- Requires dedicated knowledge or staff
- Manual input increases chance of error
- High risk of CPF miscalculations, missed AIS deadlines, or IR21 delays for foreign employees
What is Payroll Process Outsourcing (PPO)?

Payroll process outsourcing (PPO) means letting a third-party, like Sleek, handle your payroll for you. Your provider takes care of everything from calculations and statutory filings to system setup and maintenance.
Outsourced payroll often includes:
- Monthly payroll runs
- Payslip generation
- CPF, SHG, SDL submission
- AIS registration and IR8A filing
- IR21 tax clearance for foreign employees
- Reporting and deadline reminders
Providers like Sleek offer access to cloud-based payroll platforms such as Talenox. They may also send automated email reminders to ensure timely CPF payments and IRAS submissions. The goal is to free up your internal team, minimise errors, and ensure you stay fully compliant.
Pros
- Statutory compliance handled by experts
- Reduced admin workload
- Scalable and cost-efficient
- Timely, accurate filings
- Access to secure, cloud-based platforms like Talenox
Cons
- Less hands-on control (though full visibility is maintained)
- Requires initial onboarding setup
In-house payroll vs payroll outsourcing Singapore

Feature / Factor | In-House Payroll | Payroll Process Outsourcing (PPO) |
Setup & Operations | Managed by internal team using software | Fully managed by a third-party provider |
Time Requirement | High, with monthly processing and filings | Low, as processes are automated and supported |
Compliance Handling | Responsibility stays within the company | Managed by specialists, including CPF, IR8A, IR21 |
Error Risk | Higher due to manual work | Lower due to expert handling and automation |
Scalability | Can be difficult as team size increases | Easily scales with business growth |
Cost | Ongoing staff time and software expenses | Fixed per-employee fee (e.g., Sleek charges $300 per employee annually for end-to-end payroll compliance) |
Doing payroll in-house works if your team’s equipped. But for most growing businesses, outsourcing is quicker, safer, and frees up the team’s essential time.
