What is an invoice dispute and what is the standard resolution process?
An invoice dispute occurs when a buyer challenges the accuracy, validity, or appropriateness of a supplier invoice. Common dispute reasons include price discrepancies versus the purchase order, quantity differences, incorrect VAT treatment, missing PO reference, goods not received, and duplicate invoices. Invoice disputes extend DSO for the supplier and delay AP processing for the buyer.
What is the standard invoice dispute resolution process?
Standard dispute resolution process: (1) Buyer identifies discrepancy during invoice validation or three-way match; (2) Buyer logs dispute in AP system with dispute reason code and supporting detail; (3) Dispute notification sent to supplier via portal, email, or EDI; (4) Supplier reviews and responds: either accepts the dispute and issues a credit note/corrected invoice, or provides evidence to support the original invoice; (5) Buyer and supplier agree on resolution; (6) If credit note: apply to original invoice and process adjusted amount for payment; (7) If original invoice upheld: approve original invoice for payment.
Frequently Asked Questions
- How can e-invoicing reduce the invoice dispute rate?
- E-invoicing reduces disputes by: (1) Format validation at source catches missing mandatory fields before delivery; (2) PO number validation against buyer systems is possible via API integration; (3) Structured data enables automated matching on receipt, catching discrepancies immediately; (4) Digital delivery provides unambiguous delivery evidence; (5) Peppol message acknowledgments confirm receipt in the buyer's network. Typical e-invoice dispute rates are 1-3 percent versus 5-15 percent for paper/email PDF invoices.
- What is a dispute reason code and how is it used?
- A dispute reason code is a standardized classification code assigned to an invoice dispute to describe the reason for the challenge. Common reason codes include: PR (price error), QT (quantity error), TD (tax or VAT error), PO (missing or invalid PO reference), NR (goods or services not received), DU (duplicate invoice), and UN (unapproved change from contracted terms). Standardized reason codes enable dispute trend analysis, supplier performance reporting, and root cause remediation.
