3-Way Matching Automation

Automatically match invoices to POs and receipts. Resolve discrepancies before they become problems.

3-way matching is essential for AP control, but manual matching is time-consuming and error-prone. Nexus AP automates the matching process, instantly comparing invoices to purchase orders and goods receipts.

The Challenge

Manual 3-way matching requires staff to locate and compare three separate documents for every invoice. This takes time, creates bottlenecks, and often results in exceptions that delay payment.

The Solution

Nexus AP automatically matches invoices to POs and receipts based on configurable tolerances. Clean matches flow straight to payment. Exceptions are flagged with specific discrepancy details for quick resolution.

Frequently Asked Questions

What matching tolerances can I set?

You can configure price tolerance (e.g., ±2%), quantity tolerance, and line-level vs header matching. Tolerances can vary by vendor, commodity type, or amount threshold.

How do you handle invoices without POs?

Non-PO invoices can follow a separate approval workflow based on amount, vendor, or expense category. You control when PO matching is required vs optional.

What happens when there's a discrepancy?

Exceptions are flagged with specific details (e.g., "Invoice quantity 100 exceeds PO quantity 95"). Exceptions route to the appropriate person for resolution with full document access.
