HR and payroll you host yourself
Crow HR is free, MIT-licensed HR and payroll software for Singapore SMEs. It runs on your own server, and your employees' data stays with you.
Singapore payroll
Monthly runs with CPF (OW and AW ceilings, SPR rates), SHG funds, SDL and an FWL estimate; itemised payslips; the CPF EZPay file, a bank file and an IR8A export to upload yourself.
Shown working
Every CPF figure shows its working, the rate table it used and a link to the source. The statutory engine is tested against CPF’s published examples and its online calculator.
