The verdict in three sentences
Running payroll on a spreadsheet exposes you to two risks: a calculation error that upsets staff, and an NSSF/PAYE penalty that hits the company hard. Payroll software automates gross-to-net, applies current contribution rates, disburses salaries by MoMo and generates the compliant PDF payslip. In 2026, budget KES 150k-600k (about 500k-2M XOF) for a tool that keeps you compliant and saves hours every month.
Gross to net: 2026 deductions (Kenya)
Going from gross to net stacks several deductions. Here are 2026 orders of magnitude for an employee in Kenya (estimate, confirm against official bands).
| Contribution | Base | Employee share | Employer share |
|---|---|---|---|
| NSSF (tier I + II) | Capped salary | 6% | 6% |
| NHIF / SHIF | Gross bands | Banded amount | — |
| PAYE | Taxable income | Progressive scale | — |
| Housing levy | Gross | 1.5% | 1.5% |
| Total order of magnitude | — | ~15-25% | ~7.5% |
On a gross of KES 80,000, the net paid lands around KES 58,000-64,000 once employee deductions and PAYE apply — a calculation the software redoes without error every month.
What the software actually automates
The value is not just the maths: it is the whole chain, from entry to disbursement.
| Feature | Benefit | Priority |
|---|---|---|
| Automatic gross → net | Zero calculation error | Essential |
| Up-to-date contributions | NSSF/PAYE compliance | Essential |
| Compliant PDF payslip | Ready to hand over | Essential |
| MoMo disbursement | Salaries paid in 1 click | High |
| Statutory returns | Files ready to file | High |
| Leave / absence | Automatic accrual | Medium |
| History per employee | Full traceability | Medium |
MoMo disbursement transforms payroll: instead of handing out envelopes, the company pushes salaries to employees' mobile money accounts, with an operator fee of roughly 1% per transfer.
Mini case study
Wanjiru runs a services SME in Nairobi with 18 employees. Manual payroll took 2 days a month and produced 2-3 errors monthly, plus a KES 55,000 NSSF back-charge last year for a mis-applied rate. Software at KES 400,000 automates gross-to-net and MoMo disbursement. Result: payroll wrapped in 2 hours, zero errors, no more penalty. The time saved alone is worth over KES 120,000/year.
