Dispute Evidence

Definition

Dispute Evidence is the "Legal Brief" a merchant submits to fight a chargeback. It is a collection of data points—invoices, shipping proofs, logs—that must prove the transaction was valid relative to the specific Reason Code filed by the cardholder.

Why it matters

Specificity Wins. Sending a tracking number for a "Fraud" dispute is useful. Sending a tracking number for a "Credit Not Processed" dispute is useless. You must answer the specific accusation made by the cardholder. A "Data Dump" leads to an automatic loss.

Signals to monitor

  • Representment Rate: The % of disputes you choose to fight vs. accept.
  • Win Rate by Code: "We win 40% of Fraud disputes but 0% of Service disputes."
  • Auto-Win Potential: Identifying cases with perfect evidence (AVS Match + 3DS Auth) that should be fought automatically.
  • Cost/Benefit: Tracking whether the cost of fighting a dispute ($15 processing fee) exceeds the transaction value.

Breakdown modes

  • The Data Dump: Uploading 50 pages of unorganized logs. The bank analyst has roughly 60 seconds to review; they will reject unorganized files.
  • Illegible Docs: Using blurry screenshots or tiny text that automated network scanners cannot parse.
  • Wrong Evidence Type: Proving delivery to "Main St" when the cardholder's billing address was "Oak St" (AVS Mismatch).

Where observability fits

Observability automates "Asset Retrieval." By linking a Dispute ID to its original Transaction ID, the system can instantly pull the relevant invoice, shipping proof, and IP logs into a standardized PDF format designed for bank approval.
