Paradigms of Audit Assurance

Why Post-Payment Audits Are Costing You Millions

Traditional contingency auditors look at old PDFs 9 to 18 months after wire clearance. By then, dollars are gone, staff has churned, and recovery is adversarial.

Legacy Post-Payment Recovery

THE LEAKY BUCKET
  • × Delayed Detection: Audits occur 6 to 18 months after invoices have already been paid in full.
  • × 25% Clawback Commissions: Third-party auditing agencies take massive percentages of whatever cash they claw back.
  • × Vendor Relationship Friction: Chasing vendors for refunds a year later sparks disputes, legal threats, and service freezes.
  • × Spot Sampling Only: Only 5% to 10% of invoices are ever manually reviewed; low-dollar creep flies completely under the radar.

Pochyaa Pre-Payment Gate

ZERO LEAKAGE
  • ✓ Zero-Second Lag: Intercepts vendor billing before accounts payable approves the invoice or schedules payment.
  • ✓ 100% Dollar Retention: Keep your money in your bank account. No clawback commissions or uncollectable balances.
  • ✓ Instant Schedule B Citations: Automatically delivers the vendor the exact contract page, clause, and math formula justifying the corrected payment.
  • ✓ 100% Line-Level Coverage: Every single invoice line item, tax calculation, and PO remaining quantity is audited every time.
The Assurance Pipeline

Three Tiers of Deterministic Defense

Every invoice is subjected to a comprehensive collect-all audit. We never fail-fast; your finance team receives an exhaustive dossier of every discrepancy found on every line.

Tier 1 • L1 Rules

Mathematical & Integrity

Validates internal arithmetic, prevents accidental double billing, and enforces operational date boundaries.

BR-101 Duplicate Invoice Critical
BR-102 Line & Tax Rollup High
BR-104 Window Expiration High
Configurable organization tolerance (default $0.00)
Tier 2 • L2 Rules

Purchase Order Binding

Binds invoice lines to authorized PO lines. Halts quantity overdraws, unapproved unit rates, and budget exhaustion.

BR-201 PO Status & Vendor High
BR-202 Quantity Overdraw High
BR-204 Billed-to-Date Limit High
Multi-strategy fuzzy & SKU line matcher engine
Tier 3 • L3 Rules

Contract Escalation Caps

Cites exact Schedule B rate sheets. Computes simple non-compounding annual escalation caps and flags rogue rate hikes.

BR-301 Rate Card Max High
BR-302 Escalation Cap Pct High
BR-303 Emergency Multipliers Warning
Exact page and clause citation audit trail
The Golden Benchmark Case

The Apex HVAC Benchmark

"If this case does not pass, nothing else matters." Here is how Pochyaa handles the industry standard test case in production.

Agreed Contract Terms
Master Service Agreement MSA-APEX-2024
Effective: 2024-01-01
Expiry: 2026-12-31
Base Rate: $450.00/hr
Annual Cap: 3.00% simple
Citation: Page 12, Section 4.2 (Schedule B)
Invoiced Claim Received
Invoice INV-2026-8819 (Apex HVAC)
Invoice Date: 2026-08-15
PO Ref: PO-99120
Billed Units: 10 Hours
Billed Rate: $520.00/hr
Invoiced Subtotal: $5,200.00 + $416.00 Tax = $5,616.00
AUDIT ENGINE STATUS REPORT STATUS: EXCEPTION
// Escalation Math Execution (Simple, Not Compound)
years = floor(days_between(2024-01-01, 2026-08-15) / 365) = 2 years
max_allowed = $450.00 × (1 + (3.00 × 0 / 100)) = $450.00/hr
actual_billed = $520.00/hr
overcharge = ($520.00 - $450.00) × 10 = +$700.00
ISSUE LOGGED: BR-301 (Rate Escalation Breach)

"Rate billed ($520.00/hr) exceeds maximum contract allowed ($450.00/hr). Schedule B stipulates $450.00/hr for Service Code HVAC_MAINT. Citation: MSA-APEX-2024 p.12 Section 4.2."
