Visa rolled out three subscription-billing-relevant rule changes between April 1 and April 25, 2026: the VAMP “Excessive” dispute threshold dropped from 2.20% to 1.50%, Level 2 commercial-card interchange incentives sunset under CEDP, and the international “Issuer Will Never Approve” reattempt fee was revised. The compound effect for subscription companies: dumb retries cost more, disputes count more, and B2B commercial-card cohorts drift to higher-cost tiers without enriched data. The durable answer is cascading PSP routing across multiple acquirers, decline-code-aware retry logic, and a multi-MID volume strategy — not a denser dunning loop.
