Quick Start Checklist: Affirm Chargeback Response

Quick Answer: How to Affirm a Chargeback as a Merchant in 2026

To "affirm a chargeback" means merchants contest (or "represent") a customer's dispute through Affirm's internal process, aiming to reverse the reversal and recover funds. Unlike traditional card chargebacks, Affirm handles these internally via its Dispute Resolution Policy (last updated July 2024, with 2026 compliance tweaks per CFPB guidelines).

Actionable 7-Step Checklist (2026 Time Limits):

  1. Receive Notification: Affirm emails you ("Dispute Initiated - Evidence Requested") or alerts via Merchant Portal. Customer disputes after failing to resolve directly with you.
  2. Log In Promptly: Access Merchant Portal or webform link (replies to email no longer supported).
  3. Decide Response: Accept (funds stay reversed, $15 Dispute Fee applies) or contest with evidence.
  4. Gather Docs (7-14 Days Window): Submit within tight deadlines--typically 7-10 days per network standards, adapted to Affirm's 15-day adjudication.
  5. Submit Evidence: Upload via webform/portal; confirmation appears, link expires.
  6. Await Adjudication: Affirm decides in ≤15 calendar days, favoring the best-substantiated claim.
  7. Outcome: Win = funds returned, no fee; lose = fee charged; appeal rare via arbitration.

Act fast--missing the 7-14 day response (per general chargeback data, Affirm-aligned) forfeits your case. Contact [email protected] for issues.

Key Takeaways & Quick Summary

What is an "Affirm Chargeback"? Meaning and Basics Explained

An "Affirm chargeback" (or dispute) occurs when a customer reports purchase issues to Affirm after unsuccessful merchant resolution. Unlike card chargebacks (issuer-driven reversals), Affirm manages these internally as a BNPL lender, pausing payments during review. Customers initiate via webform/portal; merchants get email/portal alerts.

Ideal chargeback ratio: <1% (0% best). Affirm's growth (3% BNPL market share, $9B+ loans processed) amplifies volumes, but disputes remain low if managed well. Reasons: non-delivery, defects, unauthorized--mirroring FCBA protections.
