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:
- Customer contacts you (expect this first).
- Unresolved? Customer files via Affirm (7-10 days typical initiation).
- Affirm emails merchant (instant withhold).
- Merchant responds (15 days).
- Adjudication (15 days).
- 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.
