AI Payroll Auditor:
Automated Anomaly Detection

How Automated Payroll Anomaly Detection Works
Our AI engine runs a comprehensive audit on every payroll cycle, checking hundreds of data points across your entire workforce in seconds.
1. Data Ingestion
The AI ingests all payroll data including hours worked, pay rates, tax elections, benefits deductions, and historical patterns for every employee.
2. Pattern Analysis
Machine learning models compare current payroll data against historical baselines, identifying statistical outliers and unusual patterns.
3. Anomaly Flagging
Suspicious entries are flagged with severity levels — from minor discrepancies to critical compliance violations requiring immediate attention.
4. Resolution & Approval
HR reviews flagged items with AI-suggested corrections. Once resolved, the clean payroll is approved and NACHA-compliant ACH files are generated.

Frequently Asked Questions About AI Payroll Auditing
Everything you need to know about automated payroll anomaly detection and compliance.
Space HR's AI Payroll Auditor uses machine learning algorithms trained on millions of payroll transactions to identify statistical outliers. It compares each employee's current payroll data against historical patterns, flagging anomalies such as sudden salary spikes, duplicate payments, incorrect tax withholdings, overtime miscalculations, and unauthorized deductions — all before the payroll run is finalized.
A NACHA-compliant ACH (Automated Clearing House) file follows the formatting standards set by the National Automated Clearing House Association. These files are used for electronic fund transfers including direct deposit payroll payments. Space HR automatically generates NACHA-compliant ACH files with proper record formatting, routing validation, and batch totals to ensure seamless bank processing.

The AI auditor verifies each step against current tax tables and flags any calculation errors.
The AI detects a wide range of anomalies including: duplicate employee payments, ghost employee entries, overtime calculation errors, incorrect tax bracket applications, missing or invalid Social Security numbers, unauthorized pay rate changes, benefits deduction discrepancies, retroactive pay miscalculations, and FLSA minimum wage violations.
