Subject: 60% win-rate on chargebacks vs your current 18%

Hi {first} — most {their category} merchants accept chargebacks because
disputing takes 30 min/case for a 50/50 outcome.

We draft the rebuttal: pull order data, frame the evidence the right way,
estimate win-probability. $99/dispute. Cancel after one if not seeing lift.

Free first dispute. Reply with a recent reason code (fraudulent / 
product_not_received / subscription_canceled).

Documentation

chargeback-drafter

Drafts chargeback dispute responses for Stripe/Square/Adyen merchants. Reads order + claim + support history; outputs a ready-to-paste rebuttal letter, evidence checklist, and an honest win-probability estimate.

Pricing

  • $99/dispute — pay-per-use
  • $499/mo — unlimited disputes for a single merchant
  • $1,499/mo — agency tier; up to 25 merchants
  • 25% rev-share on recovered chargeback funds (alternative)

The cost edge: Claude Sonnet at ~$0.30/dispute. We charge $99. Massive margin even before factoring the 60-90% rep-saved-by-recovery value to the merchant.

Why merchants pay

  • Average chargeback lost = $50-500 in disputed amount + $15-100 fee
    • lost product/service.
  • Win rate on un-disputed: 0%. Win rate on naively-disputed: 15-20%.
  • Win rate with a well-structured letter that hits the issuer's fact-checking checklist: 50-75%.
  • A merchant with 50 chargebacks/mo at $80 average × 50% lift in win rate = $2,000/mo recovered. Pays $499/mo subscription with margin to spare.
