Flute

Flute gives software platforms a faster way to embed payments, without building and maintaining the infrastructure. Embed card, ACH, tap to pay, and digital wallet payments through a single REST API, with a sandbox, real-time webhooks, and clear documentation that make integration straightforward. A brandable hosted checkout, plus customizable invoices and dashboards, keep the experience on your brand, not ours.

Behind the scenes, Flute handles PCI compliance, underwriting, fraud monitoring, and funding, so your team can stay focused on your product. Give your users the tools they actually need: flexible payment options, digital invoicing, recurring and subscription billing, a secure customer vault, advanced reporting, next-day funding, instant payouts, and access to working capital.

Flexible pricing — flat rate or custom interchange-plus, volume-based, or dual pricing — fits a range of business models, with no long-term contracts. Security is held to a high standard with PCI DSS Level 1 compliance, network tokenization, encryption, BIN blocking, and Level 2 and Level 3 data optimization.

With U.S.-based support for integration and ongoing optimization, Flute helps vertical SaaS platforms and ISVs turn payments into a revenue stream while keeping their customers' experience consistent and on-brand.
