Flute

Flute is a payments and merchant services platform built so growing businesses can run on one system rather than juggle a stack of separate tools. Accept payments in person and online — card-present, card-not-present, ACH, tap to pay, and digital wallets — through plug-and-play hardware, mobile devices, or a virtual terminal that can activate the same day. From the same platform, send digital invoices by text or email, set up recurring billing, store payment details in a secure customer vault, and keep an eye on everything from a redesigned dashboard with near-real-time reporting. Surcharging, dual pricing, and cash discounting help offset card fees, so you keep more of every sale. Money moves on your schedule with next-day funding or instant payouts, and working capital is there when you’re ready to grow. Security runs in the background with PCI DSS Level 1 compliance, network tokenization, encryption, and fraud monitoring, all backed by U.S.-based support for setup and beyond. Flute was built for the businesses powering the everyday economy, including retail, health care, wellness, beauty, automotive, veterinary, and professional services. Enterprise-grade tools without the headaches or the price tag.
