O que É Conciliação Tripartite
Alinhar ordem de compra, recebimento e fatura antes de pagar um fornecedor.
Explicação Detalhada
Reduz fraude e erros. Tolerâncias lidam com variações menores como frete.
Exemplo
CP paga somente quando a linha da OC, recebimento e quantidades da fatura correspondem.
Por Que É Importante
Controle padrão para um processo saudável de compra-a-pagamento.
Fatos principais
- 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.
Como aparece na prática
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.
Erros comuns
- 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.
Perguntas frequentes
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.
