Visa and Mastercard classify certain merchant category codes (MCCs) as high-risk based on chargeback history, regulatory exposure, and account-termination patterns. Mainstream processors (Stripe, Square, PayPal, Helcim) automatically decline or terminate accounts in restricted MCCs. Specialty processors (PaymentCloud, Easy Pay Direct, Instabill, eMerchantBroker) underwrite the risk and charge accordingly.
The cost stack: rates 1%–2% above low-risk equivalents, a rolling reserve of 5%–10% of monthly volume held for 90–180 days, an underwriting/setup fee of $99–$499, and frequently a multi-year contract with ETF. None of this is negotiable upfront, but after 6–12 months of clean payment history with low chargebacks, you can usually negotiate down the reserve and rate.
