Why SMEs switch to AIMM
Flat pricing, not per-employee
Other Singapore payroll software charges per head. At 20 employees, that's S$100+/month. AIMM is S$29 flat.
Built for finance operators
AIMM is designed for founders and finance managers who run payroll themselves — not for HR managers who need a full HRMS.
Full compliance workflow
CPF, SDL, SHG, IR8A, IR21, eZpay, GIRO — all in one monthly cycle with evidence at each step.
Transparent about certification
We tell you exactly where we are with IRAS AIS certification and IMDA PSG pre-approval. No vague claims.

Singapore payroll software questions
Is AIMM IRAS AIS certified?
AIMM is built to IRAS AIS Category A standards with a direct AIS-API 2.0 integration using FAPI 2.0 authentication (PAR, PKCE, DPoP). IR8A, Appendix 8A, and IR21 filing flows are built and tested. The formal certification is in progress — the technical capability is production-ready.
Does AIMM support CPF APEX?
Yes. AIMM has a CPF APEX API direct submission module that submits CPF contributions directly to CPF Board via the APEX platform, replacing manual CSV upload. It includes idempotency, retry/backoff, and a two-person approval gate. Production activation requires CPF APEX API credentials.
Can I import employees from Excel?
Yes. AIMM supports CSV/Excel import with auto-detection for Talenox, Payboy, HReasily, JustLogin, and generic formats. Field mapping is handled automatically based on header aliases, and a preview lets you verify before committing.
What about Xero integration?
AIMM has a full Xero integration with OAuth 2.0, chart of accounts import, GL mapping, and payroll journal sync via Xero's ManualJournal API. QuickBooks Online integration is also available with the same journal sync pattern.
