With subscription-based pricing and 0% markup on direct-cost interchange, Stax saves businesses up to 40% on payment processing fees — no hidden costs, no percentage markups. The platform includes Stax Pay for in-person, online, and mobile payment acceptance; Stax Bill for automated recurring billing and invoicing; CardX for compliant credit card surcharging; and Stax Connect, an embedded payments solution that enables SaaS companies and ISVs to integrate full-stack payment processing directly into their software. As an end-to-end processor, Stax handles the entire transaction lifecycle in-house — from authorization to settlement — giving businesses and software platforms more control, better economics, and dedicated support. Over 30,000 businesses trust Stax to process more than $30 billion in payments.
