Understanding Affirm Disputes: Process, Rights, and Timelines

Affirm disputes arise when customers claim issues (e.g., non-delivery) after failing to resolve directly with you. They submit via Affirm's webform; Affirm notifies you by email, withholds funds, and investigates.

Buyer/Seller Rights: Affirm resolves based on "best evidence." Customers get consumer protections; merchants retain rights under your agreement--no alterations unless stipulated. Disputes don't void contracts.

Full Lifecycle:

  1. Customer contacts you (expect this first).
  2. Unresolved? Customer files via Affirm (7-10 days typical initiation).
  3. Affirm emails merchant (instant withhold).
  4. Merchant responds (15 days).
  5. Adjudication (15 days).
  6. Resolution: Funds to winner; loser pays $15 if merchant.

Unlike card networks (15-45 days response), Affirm handles directly--faster for BNPL under $100 but buyer-favored.

Common Reasons for Affirm Disputes and When They Get Affirmed

Top reasons (40% fraud-related; 15-20% friendly fraud rise):

Affirmed for Merchants When: Strong delivery proof (e.g., signed POD); comms showing resolution attempts; policy adherence. Lost on blurry photos or no timeline--e.g., BabyGold.com lost on "tiny/flimsy" claims without counter-images.

Mini Case: Merchant lost "non-delivery" sans tracking; won appeal with USPS proof.

Step-by-Step Guide: How to Respond to an Affirm Dispute as a Merchant

  1. Receive Notification: Check "Dispute Initiated" email--note reason, amount, link.
  2. Access Portal/Webform: Log in within 15 days (webform expires post-response).
  3. Review Customer Claim: Gather your evidence (see below).
  4. Submit Response: Upload via "Take Action." Include summary.
  5. Await Adjudication: 15 days; track in Disputes Dashboard.
