A high-risk merchant account is a merchant account opened for a business that mainstream payment facilitators exclude or restrict: supplements with health claims, continuity offers, CBD and similar categories. You apply to a specialist provider, an underwriter reviews your statements, processing history and product, and you get your own merchant ID once your category is accepted. This site uses PaymentCloud as its worked example of the path. It is one provider among several, and the review describes the account type rather than ranking providers.
Who it fits
It fits a seller who has been closed by a payment facilitator, or expects to be, because the product, the claims or the chargeback pattern fall outside a platform's rules. PaymentCloud's nutraceutical page says many popular payment platforms put certain supplements under their restricted-business policies, especially products with controversial ingredients or aggressive health claims.
What it costs
Pricing is quoted per business. PaymentCloud's educational fee guide uses 3.5% plus $0.30 per transaction for an online supplement store doing $25,000 a month as an example, and providers can add a rolling reserve that holds back part of each payout against chargebacks. Budget for a higher rate than a payment facilitator's published one.
What it does not do
A merchant account approves you to take cards. It does not build pages, host order bumps or split-test a checkout, so you connect it through a gateway such as NMI or Authorize.net to the checkout you run. For the choice against Stripe, read high-risk merchant account vs Stripe.
