Itemize every line
A single final number invites suspicion and hides genuine errors.
Volume 06, Chapter 9
Payroll Basics
Gross pay is the amount agreed with the employee. Net pay is what actually lands in their account. Every deduction between the two must be shown, not just assumed.
The Golden Rule
A payslip that only shows the final number invites the exact confusion it should prevent.
Payroll's one job: turn each employee's agreed terms into an accurate, on-time payment, every pay period, with every line visible.
Accuracy & timelinessAn underpayment breaks a promise; late pay breaks trust.
Segregation of dutiesWhoever calculates the pay shouldn't be the only one who approves it.
ConfidentialitySalary data follows the access rule strictly.
One person, no checks
Calculating and paying alone removes the safeguard against mistakes and fraud.
Dates aren't flexible
Even brief, repeated delay damages trust disproportionately.
No record, no defense
Without a dated record, disputes and audits become reconstructions from memory.

Definition
Imagine a rumour spreads among a team of tailors that pay is worked out "differently for different people." No one has any actual evidence, only a suspicion, but suspicion is enough to poison morale. The cause almost never turns out to be unfairness. It's usually a payslip that just says one final number, with no breakdown of how it got there. When employees can't see the arithmetic, they assume the worst.
Payroll
is the complete, recurring process of paying employees correctly, on time, with every deduction properly calculated and recorded. It sits exactly on the border between Volume 04's HR records and Volume 07's finance systems, this chapter gives the basics; full financial mechanics (taxes, statutory deductions, budgeting for payroll) belong to Volume 07 and Volume 09: Legal Compliance.
In One Sentence
Payroll has one job: turn each employee's agreed terms (Chapter 8's hiring, documented in an employment contract) into an accurate, on-time payment, every single pay period, with no surprises for the employee and no untraceable cash for the business.

The Payroll Calculation, Step by Step
1. Gross Pay
The agreed salary or wage before any deductions.
2. Add Extras
Overtime, bonus, commission, allowances.
3. Statutory Deductions
Tax, pension, any other legally required withholding.
Vol 094. Other Deductions
Loan repayments to the business, benefit contributions.
5. Net Pay
What actually lands in the employee's account.
| Step | What Happens |
|---|---|
| 1. Start with gross pay | The agreed salary or wage before any deductions |
| 2. Add anything owed on top | Overtime, bonus, commission, allowances |
| 3. Subtract statutory deductions | Tax, pension, and any other legally required withholding (Volume 09) |
| 4. Subtract other agreed deductions | Loan repayments to the business, benefit contributions |
| 5. Result: net pay | What actually lands in the employee's account |
Worked example, a MANIAC MINDZ tailor:
| Amount | |
|---|---|
| Gross monthly salary | ₦120,000 |
| + Overtime (agreed rate) | ₦8,000 |
| − Statutory tax withholding | −₦9,000 |
| − Pension contribution | −₦6,000 |
| = Net pay | ₦113,000 |
Every one of these lines must be visible to the employee, not just a single final number, a payslip that only shows "₦113,000 paid" invites the exact confusion Volume 04, Chapter 5's HR chapter warned against.
Memory Trick
Gross pay is what was agreed. Net pay is what is actually paid. Every deduction between the two must be shown on the payslip, not just assumed or left out.

What a Payroll System Must Get Right
| Requirement | Why |
|---|---|
| Accuracy | An underpayment is a broken promise; an overpayment is money the business may never recover |
| Timeliness | Late pay is one of the fastest ways to damage trust and attendance |
| A record for every payment | Feeds Volume 04's financial records and protects both sides in a dispute |
| Segregation of duties | The person who calculates payroll shouldn't be the only person who approves and pays it, see Volume 11: Internal Controls |
| Confidentiality | Salary data follows Volume 04, Chapter 8's access rule strictly |

Example Story: The Payslip That Ended the Rumour
Here's the full version of the rumour from the start of this chapter.
A quiet rumour spread among MANIAC MINDZ's tailors that pay was calculated "differently for different people," with no evidence beyond suspicion, exactly the kind of trust crack Volume 04, Chapter 8's shared-spreadsheet story warned about, but from the opposite direction: not too much visibility, but too little.
The fix was simple: itemized payslips for everyone, showing gross pay, every addition, every deduction, and net pay, the same five-step breakdown as Section 2, every month, without exception. The rumour didn't survive its first month against real, individual transparency.

Common Mistakes
Common Mistake #1: A Single Final Number With No Breakdown
Invites suspicion and makes genuine errors impossible to catch. Always itemize.
Common Mistake #2: One Person Both Calculating and Paying Alone
Removes the check that catches honest mistakes, and the safeguard against dishonest ones. See Volume 11: Internal Controls.
Common Mistake #3: Treating Payroll Dates as Flexible
Even a few days' delay, done more than once, damages trust disproportionately to the inconvenience it seems to cause.
Common Mistake #4: No Payroll Record Kept
Without a dated, itemized record per employee per period, both a dispute and a tax audit become reconstructions from memory, precisely what Volume 04, Chapter 1 warned against.

Quiz Yourself
Quiz 1
What are the five steps from gross pay to net pay?
Start with gross pay → add extras (overtime, bonus, commission) → subtract statutory deductions → subtract other agreed deductions → arrive at net pay.
Quiz 2
Why should the same person not both calculate and approve/pay payroll alone?
Segregation of duties catches honest errors and prevents a single person from having unchecked control over money leaving the business.
Quiz 3
What actually resolved the payslip rumour at MANIAC MINDZ?
Itemized, transparent payslips for everyone, showing every addition and deduction, not a policy announcement, but visible, individual proof.

Practice Exercise
- Pick one employee's most recent pay. Reconstruct it through the five steps in Section 2, can you account for every naira?
- Confirm whether your current payroll process has segregation of duties, per Section 3.
- Check whether every employee currently receives an itemized payslip, not just a final number.

Quick Summary
Quick Summary
- Payroll turns agreed terms into accurate, on-time pay: gross pay → additions → statutory deductions → other deductions → net pay, every line shown, not just the final number.
- A payroll system must be accurate, timely, recorded, segregated across at least two people, and confidential.
- Itemized payslips prevent the suspicion that grows from a single opaque final number.
- Volume 06 complete. Next, Volume 07: Finance picks up payroll's financial mechanics in full, alongside the rest of the money.
