What Flux Payments is
Flux Payments combines card, ACH, and stablecoin processing in a payment platform for businesses. One integration accepts Visa, Mastercard, American Express, and Discover. Its Flat Rate plan lists 2.9% + 30¢ per transaction; ACH bank transfers are listed at $5.00 flat, and stablecoin payments are listed as Free (0%). Consumer Pass-Through adds processing fees to customer checkout where local rules allow. Recurring billing includes automatic retries and dunning emails for failed payments. Flux says card payments typically settle in 1–2 business days, ACH in 1–3 business days, and stablecoins instantly to a wallet. Integrations include QuickBooks Sync, a free WooCommerce plugin, Set Forth, and a GoHighLevel integration marked as in the works. QuickBooks Sync sends and categorizes transactions, invoices, fees, and refunds. Developers can use SDKs for Node.js, browser, React Native, iOS, and Python, or a REST API with interactive documentation. Flux says it is SAQ-D, PCI DSS Level 2 certified and captures card details in origin-isolated iframes. Accounts processing under $100,000 a year in card volume may be subject to a $20 monthly account fee.
