Invoice reconciliation is the process of comparing invoices with purchase orders, delivery notes, and payment records to ensure accuracy and detect discrepancies.
Businesses typically perform invoice reconciliation monthly or quarterly. The process involves:
For example, a company might notice an invoice for 100 units when only 95 were delivered. This discrepancy would trigger an investigation to determine whether the error was in ordering, receiving, or billing.
| Type | Description | Common Use Case |
|---|---|---|
| Three-way match | Compares purchase order, invoice, and delivery note | Regular vendor payments |
| Two-way match | Compares invoice with delivery note (no purchase order) | Emergency purchases |
| Self-billing | Customer creates supplier's invoice based on their own records | Long-term supplier relationships |
Invoice reconciliation prevents errors and fraud. According to the Association of Certified Fraud Examiners, organizations lose 5% of revenue annually to fraud. Regular reconciliation can reduce this risk.
I once worked with a client who discovered a recurring $500 monthly charge from a discontinued service through regular reconciliation. Over five years, this would have cost them $30,000.
Another misconception is that automated systems eliminate the need for reconciliation. While software can flag discrepancies, human review remains essential for complex cases requiring judgment calls.
The American Institute of CPAs emphasizes that proper reconciliation requires understanding both the numbers and the underlying business processes.
