Not legal or financial advice. This page is not a substitute for your processor's dispute console, card-network reason codes, acquirer playbooks, a licensed attorney, or your judgment. It describes a merchant ritual: use Pingpong to write your chargeback response description, then pressure-test compelling evidence and timelines before you submit. Nothing here coaches consumers on filing chargebacks, inventing claims, or keeping goods they reverse.
Notification hits Slack or email. Reason code in the subject line. One model already offered a three-paragraph "we delivered, please deny" letter. Ops has tracking; support has chat; finance has the fee schedule. The submit button is the next social act. That is the moment this page is for.
People searching how to respond to a chargeback or chargeback rebuttal letter usually get template PDFs and war-story forums. Those can help. This page is narrower. It treats the response as a written object that must map to the reason code, the evidence you can prove, and the clock you are actually on.
This is not before you file a chargeback (buyer-side). It is not before you return. It is merchant-side respond / represent: the sale was real or the claim is mismatched, and you need a clear description plus compelling evidence before the deadline. Stripe-shaped sibling: Stripe dispute evidence. Second-presentment sibling: dispute representment.
Use Pingpong to write your dispute description. Default chain: Grok, then Perplexity, then ChatGPT, then Gemini, then Claude. First model drafts the response narrative. Later models challenge gaps: wrong code, soft proof, timeline risk, attachments that hurt more than they help. Brand: Pingpong at pingpongit.com. Not getpingpong.ai.
Definition: What is Pingpong. Mechanism: How it works. Hub: Dispute cases. Founders who also own checkout risk: For founders.
Your first eligible web review is free. Web Plus $19.99/month, web Pro $124.99/month. iOS: three free Pingpongs, then Plus $24.99/month or Pro $59.99/month. Start free on pingpongit.com. Full table: pricing.
Pays-for-itself framing: defending one mid-ticket chargeback you would otherwise accept can cover a long stretch of Plus. The product does not promise win rates. It makes weak descriptions harder to submit unnoticed.
The merchant ritual before Submit
Read the reason code and the processor's evidence checklist for that code. Gather what you can prove: fulfillment status, customer communications, cancellation or refund attempts, authorization data you are allowed to store, policy excerpts the buyer saw. Restate the claim in the cardholder's words, not your internal slang. Draft a short dispute description that answers that claim. Run Pingpong on the draft plus the evidence list. Edit. Upload. Submit before the deadline. If you cannot prove the sale, refund early and stop spending cycles on fiction.

Reason codes, compelling evidence, timelines
Reason codes are not vibes. Fraud, authorization, processing error, and consumer disputes ask for different proof. Compelling evidence usually means dated, customer-linked artifacts: delivery confirmation to the address on file, IP/device signals where relevant, usage logs for digital goods, signed contracts, cancellation timestamps, refund receipts. Timelines are processor-specific and unforgiving; a beautiful letter after the window is theater.
What usually breaks responses: arguing "friendly fraud" without proof of receipt; pasting a shipping label as delivery; ignoring a partial refund already issued; attacking the customer in tone; uploading internal tickets the buyer never saw; missing the submit clock while waiting for a perfect PDF.
Hard line: legitimate merchant defense only. No coaching to deny valid claims, fabricate scans, or retaliate against cardholders who correctly disputed unauthorized use.
How the five-model handoff works on a chargeback response
Example shape: Processor PROCESSOR, reason code CODE, amount AMOUNT, order ORDER_ID, claim summary TEXT, evidence inventory LIST, deadline DATE. Write my chargeback response description, map each paragraph to the reason code, and list compelling evidence to upload versus omit. Flag timeline risk. Do not invent proof I did not list.
Grok drafts. Perplexity through Claude review in sequence. You leave with a tighter description and a gap list. Architecture: Sequential vs parallel AI. Framing: AI second opinion. Debias: Debias AI.
Future PDF pack path (not live)
Today Pingpong writes and pressure-tests the dispute description you paste into your processor. A future API path may return a PDF evidence pack for upload (including Stripe-shaped packets). That endpoint is not live today. Do not delay a ticking response waiting for it. Use the sequential review now; assemble files in the console you already have. Existing API orientation: developer docs.
When to skip
Skip for trivial accepts, counsel-owned cases, and claims you already know are valid. Save the free eligible review for high-ticket responses, mismatched reason codes, or thin evidence you almost submitted as-is. Stripe-focused write-up: Stripe dispute evidence. Representment: dispute representment. Hub: dispute cases.
