## Part 1: PO Matching — 2-Way, 3-Way, and 4-Way
### Matching Types
| Match Type | Documents Compared | What Is Verified |
|---|---|---|
| **2-way match** | PO vs. supplier invoice | Price, quantity, terms |
| **3-way match** | PO vs. goods receipt (GRN) vs. supplier invoice | Price, quantity, and physical receipt confirmed |
| **4-way match** | PO vs. GRN vs. inspection record vs. supplier invoice | Price, quantity, receipt, and quality/inspection sign-off |
**Best practice**: 3-way matching is the minimum standard for goods purchases. 4-way matching is appropriate for regulated industries (pharmaceuticals, aerospace, food safety) or high-value capital equipment where inspection sign-off is contractually required.
### Purchase Price Variance (PPV)
PPV arises when the actual invoiced price differs from the standard or PO price:
```
PPV = (Actual Price − Standard/PO Price) × Quantity Received
```
- **Favorable PPV**: actual price < PO price → credit to PPV account.
- **Unfavorable PPV**: actual price > PO price → debit to PPV account.
**Accounting treatment by jurisdiction:**
| Jurisdiction | Standard | PPV Treatment |
|---|---|---|
