Audit Your Payroll CSVWhy Gross-to-Net Discrepancies Happen in Payroll Sheets
Spreadsheet Formula Over-writes
When cells in a spreadsheet are manually edited or copied across rows, automated sum formulas can be accidentally overwritten with hardcoded numbers.
Deduction Sign Inversions
Deductions entered as negative numbers (e.g. -₦10,000) inside a spreadsheet formula configured to subtract values end up inadvertently adding money to net pay.
Rounding & Fraction Discrepancies
Kobo rounding differences across multiple allowance components can accumulate into noticeable variances between calculated take-home pay and bank disbursement instructions.

Audit Your Payroll CSVFrequently Asked Questions
What payroll files can I upload?
Payroll Auditor currently accepts CSV files.
Does Payroll Auditor replace my payroll software?
No. Payroll Auditor works with the payroll you've already prepared. Upload your existing CSV and use it as a verification step before payment.
Is my payroll data uploaded to a server?
No. Payroll processing is performed in your browser rather than sending your payroll file to a backend for analysis.
What does Payroll Auditor check?
It checks supported payroll calculations, data integrity and applicable statutory conditions.
Does zero variance mean my payroll is fully compliant?
No. Zero calculation variance does not necessarily mean every statutory or data-integrity check has passed. Payroll Auditor reports these findings separately.
Is Payroll Auditor a tax filing service?
No. Payroll Auditor is a payroll verification tool. It does not replace tax filing, payroll processing or professional accounting advice.
