The verdict in three sentences
A company of 30 to 80 employees processing payroll by hand loses 3 to 5 days a month and produces 4 to 8 % erroneous payslips, fuelling disputes and social-security reassessments. An HR/payroll SaaS at 40,000-100,000 FCFA/month by headcount automates the essentials; a custom application (build 5,000,000-9,000,000 FCFA) embeds your agreements, bonuses and bulk mobile transfers. The switch pays off as headcount and bonus complexity rise.
HR SaaS or custom app: the comparison
SaaS covers standard payroll well. Once you stack up bonuses, allowances and internal rules, a dedicated app avoids the Excel workarounds that reintroduce errors.
| Criterion | HR/payroll SaaS | Custom application |
|---|---|---|
| Upfront cost | 0 FCFA | 5,000,000 - 9,000,000 FCFA |
| Monthly cost | 40,000 - 100,000 FCFA | 70,000 - 130,000 FCFA (maintenance) |
| 3-year cost | 1,440,000 - 3,600,000 FCFA | 7,520,000 - 13,680,000 FCFA |
| Social-security / tax calc | Standard | Custom-configured |
| Mobile-money salary transfer | Plan-dependent | Native, bulk |
| Time and leave tracking | Generic module | Digital and tailored |
| Payslip error rate | 2 - 4 % | under 1 % |
The payroll numbers
Manual payroll is expensive in time and errors. Here is the typical impact of an HR app for a company in 2026 (order of magnitude).
| Indicator | Manual payroll | With the app |
|---|---|---|
| Payroll processing time | 3 - 5 days | 0.5 - 1 day |
| Payslip error rate | 4 - 8 % | under 1 % |
| Social-security / tax calc | Manual, risky | Automated |
| Salary disbursement | Branch queue | Bulk mobile money |
| Payslip | Paper | Digital by email |
| Cost of an HR officer | 300,000 FCFA/month | time redeployed |
Mini case study
Ms. Naidoo runs a 50-employee SME in Johannesburg. Her HR officer at 300,000 FCFA/month spends 4 days a month on payroll, about 20 % of her time, roughly 60,000 FCFA/month of value. With a 6 % error rate she corrects 3 payslips a month, each fix costing time and credibility. The app at 6,500,000 FCFA divides processing time by 4 and the error rate by 6; factoring in one avoided social-security reassessment, payback lands around 24 to 30 months.

Yes: the app generates a disbursement file and triggers transfers in a batch, with per-employee confirmation. It removes branch queues and number-entry errors.

The 2026 scales are configured in the app; every payslip applies contributions and withholdings automatically, cutting reassessment risk.

Yes: digital time tracking, leave requests and balances are handled in the same app and feed payroll directly.
