Automated three-way-matching for invoice approval

Purpose

1. Automate the three-way matching process for invoice approvals by cross-verifying purchase orders (POs), delivery receipts (goods received notes or GRNs), and supplier invoices.

2. Ensure only valid, received, and correctly priced deliveries are approved for payment, preventing fraud, duplicate payments, and manual processing errors.

3. Integrate data from procurement, inventory, and accounts payable systems to streamline supplier relationship management and payment cycles.

4. Provide audit trails and compliance documentation for every matched and approved transaction within the construction materials/aggregates industry context.

Trigger Conditions

1. New supplier invoice is received via email, direct upload, or integration with financial ERP.

2. Associated purchase order is marked as completed or updated in procurement system.

3. Delivery is logged via inventory/warehouse management, triggering a goods received note (GRN).

4. Any time a mismatch, discrepancy, or missing document is detected at any step.
