Was Ist Drei-Wege-Abgleich
Abstimmung von Bestellung, Wareneingang und Rechnung vor der Bezahlung eines Lieferanten.
Ausführliche Erklärung
Reduziert Betrug und Fehler. Toleranzen handhaben kleinere Abweichungen wie Fracht.
Beispiel
Die Kreditorenbuchhaltung zahlt erst, wenn Bestellposition, Wareneingang und Rechnungsmengen ĂĽbereinstimmen.
Warum Es Wichtig Ist

Wichtige Fakten
- Three-way matching is an AP control that compares three documents before approving an invoice for payment: Purchase Order (PO), Goods Receipt Note (GRN), and Vendor Invoice.
- Goal: prevent payment for goods not ordered, not received, or invoiced at the wrong price.
- Modern AP automation tools achieve 75-90% straight-through processing on three-way-matched invoices — meaning no manual review needed when all three documents agree.
- Tolerance thresholds (typically 1-5% of invoice value) allow minor discrepancies to auto-approve without exception handling.
- Two-way matching (PO + Invoice, no GRN) is used for services and intangibles where 'receipt' isn't a physical event.
Wie es in der Praxis aussieht
An enterprise's AP team receives a $14,800 vendor invoice referencing PO #2026-1024. The system auto-pulls: PO line item $14,800 (500 units × $29.60), GRN confirms 500 units received, invoice charges 500 × $29.60 = $14,800. All three match exactly within 1% tolerance — payment is auto-approved within 4 hours. The same vendor invoiced $15,200 the prior week (500 × $30.40) which exceeded the 2% tolerance threshold; AP sent it to manual review and discovered a price-increase notification the procurement team had missed.
Häufige Fehler
- Setting tolerance thresholds too tight (under 1%) — creates excessive manual review for trivial penny-rounding differences.
- Setting tolerances too loose (over 10%) — defeats the control's fraud-prevention purpose.
- Not requiring GRNs for physical goods deliveries — breaks the three-way match and forces manual verification.
- Treating service invoices like product invoices — services need different match logic (often two-way: contract + invoice).
- Approving invoices that fail the match without documenting why — creates audit findings and invites future fraud.
Häufig gestellte Fragen
What's the difference between two-way and three-way matching?
Two-way matching compares PO + Invoice — used for services, software licenses, and other intangibles where there's no physical 'receipt.' Three-way matching adds the Goods Receipt Note (GRN), used for physical inventory and equipment where actual delivery must be confirmed.
Why do small businesses skip three-way matching?
Volume rarely justifies the process overhead. Below ~50 monthly invoices, the controls add more friction than they save. Implementing three-way match typically becomes worthwhile around 100+ monthly invoices or when you have multiple buyers and receivers.
What tolerance should I set for three-way matching?
Common practice: 1-5% of invoice value or $50-$200 absolute (whichever is smaller). Tighter for high-value vendors, looser for low-value commodity purchases. Adjust based on your error rate.
Can three-way matching be fully automated?
Yes — modern AP automation tools achieve 75-90% straight-through processing when PO and GRN data is clean. The remaining 10-25% are exceptions requiring human review (price discrepancies, partial deliveries, missing PO references).
What about four-way matching?
Four-way matching adds inspection/quality acceptance to the three-way process — common in pharmaceuticals, aerospace, and other industries where goods can pass receipt count but fail quality checks. Most businesses don't need it.
