What is GRN Matching Audit Trail?
Definition
GRN Matching Audit Trail is a detailed, chronological record of all actions, validations, and decisions taken during the process of matching supplier invoices with Goods Receipt Notes (GRNs) and purchase orders. It provides full traceability within accounts payable, ensuring that every step in invoice processing is documented, verifiable, and compliant with internal and external audit requirements.
This audit trail acts as a transparent record that captures who performed each action, when it occurred, and what changes were made throughout the matching lifecycle.
How GRN Matching Audit Trail Works
The audit trail is automatically generated as invoices progress through matching, validation, and approval stages. Each interaction with the invoice is recorded to ensure accountability and traceability.
Data capture: Logs invoice entry, GRN details, and purchase order references.
Matching actions: Records validation steps and comparison results.
Exception tracking: Documents discrepancies and their resolution.
Approval history: Captures decisions within the invoice approval workflow.
This continuous logging ensures that every transaction can be reviewed and audited with complete visibility.
