Try using payroll softwares that can create these payslips automatically. I use
Justlogin and they can create the itemised payslips as required by
MOM. They wrote a piece on how to comply with
MOM's requirements. You can check it out:
Itemized Payslips - What you need to know?
In addition, It's priced reasonably at $5 per mth per user on top of a one-off set up and training fee of $600. Since its priced by the number of employees, it's very scalable and I didn't have to pay as much when my company downsized. Furthermore, I am able to enjoy grants from Spring Singapore and also claim PIC to cover the costs. What I like most about it is how everything is more automated - other than the itemised payslip,
CPF and tax computations can also be automated!
