The Payroll Problems Generic HR Software Gets Wrong
Payroll is not judged on the average case. It is judged on the exception, because the exception is what makes the phone ring.
Seven exceptions that regularly break otherwise-competent HR systems, and how to test each one before you buy.
1. The deduction that exceeds available pay
Loan installment, advance recovery and penalty all land in the same month. A correct engine caps recovery at available net pay, records what was not recovered, and rolls the shortfall forward. An incorrect one produces a negative net or a silently wrong figure. Test: create the case and look at the payslip.
2. The mid-month joiner’s daily rate
Prorating gross without preserving the daily rate produces a number that looks reasonable and is not. Test: hire someone on the 14th and compute their per-day rate against a full-month employee on the same salary.
3. Salary set to zero, allowances that did not follow
When an employee’s salary is zeroed, percentage-of-basic allowances should recompute to zero. Many systems keep displaying the last computed amount because it was cached from the previous payslip. Test: set a salary to zero and check whether medical allowance goes with it.
4. Penalties taken from the wrong place
A late-arrival penalty may be a fraction of a day or a flat amount, and may need to come out of leave balance before salary, respecting each leave type’s monthly limit. Most systems support one behaviour and force policy to bend around the software.
5. Split local and foreign remittance pay
Where part of compensation arrives as foreign remittance, the common workaround is two payroll runs reconciled by hand. That means two chances to be wrong and no single payslip the employee can read. Test: ask to see one payslip containing both.
6. Statutory contributions beyond the obvious
Income tax and EOBI are widely handled. PESSI, provident-fund variants, gratuity and final settlement with correct tax treatment are handled less often, and the gaps show up exactly when an employee leaves, which is the worst moment to discover a gap.
7. Payroll that never reaches the ledger
Payroll produces numbers; accounting needs journal entries. If the connection is a monthly export, someone owns a reconciliation task forever. Test: ask to watch a payroll run post to the general ledger live. You want to see the balanced journal entry, not a summary report.
Why these specific seven
Because each one of them exists in Zaffre Axon as a deliberately engineered behaviour rather than a lucky default: the net-pay floor on recovery, calendar-day proration, allowance recomputation, dual penalty modes with leave-first ordering, combined remittance payslips, PESSI and gratuity, and automatic double-entry posting from the payroll run.
They are engineered that way because each one broke somewhere first.
Bring your own hardest payroll case to the demo. Not a standard employee, but the one that causes an argument every month. That is the only demo that tells you anything.
